The TIME ATAC XC 12 [paid link] pedals are among the most advanced cross-country pedals available today, known for their lightweight carbon body, titanium spindle, and exceptional mud-shedding performance. However, even the most premium pedals require regular bearing service to maintain smooth rotation and longevity. Over time, contaminants such as dust, grit, and water can compromise the pedal’s internal bearings, causing roughness or play in the axle. This guide explains in detail how to replace or service the bearings in your TIME ATAC XC 12 [paid link] pedals to restore optimal performance.

Tools Required

8mm hex wrench
9mm socket wrench
Torque wrench [paid link]
Small flathead screwdriver
Needle-nose pliers
Bearing puller or drift tool
Replacement bearing kit for TIME ATAC XC series
Waterproof grease (medium viscosity)
Clean rags or paper towels

Understanding the Bearing System of the ATAC XC 12

The TIME ATAC XC 12 pedal uses a hybrid bearing system that combines a sealed cartridge bearing on the inboard side and a needle bearing or bushing on the outboard side. This configuration ensures low rotational resistance while maintaining a light overall weight.

The sealed cartridge bearing supports the load near the crank arm, while the bushing or needle bearing stabilizes the pedal body toward the outer edge. Because the outboard bearing experiences more exposure to the elements, it typically requires cleaning or replacement more frequently than the inboard one.

When to Service or Replace the Bearings

Servicing intervals vary based on riding conditions, but general recommendations are:

Every 3,000–5,000 km for regular XC riders
After every wet or muddy season
Whenever you notice:
- Creaking or grinding noise while pedaling
- Excessive side-to-side play in the pedal body
- Uneven or rough rotation when spinning the pedal by hand

Ignoring these signs can lead to spindle wear, which may require full pedal replacement rather than simple bearing service.

Step-by-Step Guide to Replacing or Servicing Bearings

1. Remove the Pedals from the Crank Arms

Insert an 8mm hex wrench into the back of the spindle and rotate counterclockwise to loosen. For carbon cranksets, take care not to strip the crank threads or over-torque during reinstallation.

2. Disassemble the Pedal Body

Once removed, locate the end cap on the outer side of the pedal. Using a small flathead screwdriver, carefully pry it off. Beneath the cap, you’ll find a retaining nut or lock ring that secures the spindle. Use a 9mm socket wrench to remove it.

Slide the pedal body gently off the spindle, taking note of the order of seals, spacers, and washers for correct reassembly.

3. Inspect the Bearings and Spindle

Wipe away any old grease or dirt using a clean rag. Rotate the bearings with your finger; if you feel grinding, looseness, or roughness, replacement is required. Check the spindle for wear or scoring—replace it if it shows deep grooves or discoloration.

4. Remove the Old Bearings

For the inboard bearing, use a bearing puller or drift tool to push it out from the opposite side of the pedal body. Be careful not to damage the carbon housing.

For the outboard bushing or needle bearing, use needle-nose pliers to remove it gently. If it feels tight, apply a small amount of penetrating oil and allow it to sit for a few minutes before attempting removal.

5. Clean and Prepare the Housing

Once the old bearings are removed, clean the bearing seats thoroughly. Remove any residue, corrosion, or old grease. Apply a thin coat of waterproof grease to the seats before installing the new bearings.

6. Install the New Bearings

Press the new sealed cartridge bearing into the inboard side using a press tool or a socket of matching diameter. It should sit flush with the housing.

For the outboard side, insert the needle bearing or bushing and ensure it is fully seated. Apply a light layer of grease over the visible bearing surfaces.

7. Reassemble the Pedal

Reinsert the spindle carefully through the pedal body, ensuring all seals and spacers are returned to their original positions. Reinstall the lock nut using a torque wrench [paid link] set to 6–8 Nm. Finally, press the end cap back into place.

8. Test the Rotation and Play

Spin the pedal by hand. It should rotate freely with no grinding or lateral movement. If resistance feels too tight, loosen the lock nut slightly and retighten within the specified torque range.

Optimizing Bearing Longevity

To keep your TIME ATAC XC 12 bearings running smoothly for years, follow these maintenance habits:

Clean your pedals after muddy or wet rides to prevent grit accumulation.
Avoid using high-pressure water directly on the spindle area, as it can push water into the bearings.
Re-grease the inboard seal every few months to prevent contamination.
Store your bike indoors in a dry environment to avoid corrosion.

Consistent maintenance not only extends bearing life but also ensures the pedal’s engagement mechanism performs at its best under demanding XC conditions.

Troubleshooting Common Post-Service Issues

If your pedals do not spin freely after servicing, the following may be the cause:

Overtightened lock nut: Loosen slightly to relieve bearing preload.
Misaligned bearing or seal: Ensure the bearing is seated evenly in the housing.
Contaminated grease: Use only high-quality waterproof grease; avoid thick automotive greases that restrict rotation.
Damaged spindle: Inspect for microscopic cracks or bends if rotation remains inconsistent after replacement.

Regularly checking for these issues prevents premature wear and costly damage to both pedal and crank interfaces.

Comparison: TIME ATAC XC 12 vs. ATAC XC 8 Bearing Design

While the ATAC XC 8 [paid link] shares a similar engagement mechanism, its bearing system differs slightly. The XC 8 uses a chromoly spindle and slightly heavier bearing assembly, whereas the XC 12 employs titanium spindles and higher-grade bearings for reduced weight and improved corrosion resistance. This makes the XC 12’s bearing service process more delicate but rewards riders with smoother rotation and greater durability when properly maintained.

Conclusion

Servicing or replacing the bearings in your TIME ATAC XC 12 pedals is a critical part of maintaining their world-class performance. With proper tools, care, and attention to detail, you can restore factory-smooth operation and extend the lifespan of your pedals for thousands of kilometers. Regular maintenance not only prevents costly wear but ensures that every pedal stroke delivers the efficiency, reliability, and feel that the ATAC XC 12 is designed to provide.

Posted on ,

in No category

The TIME ATAC XC 12 [paid link] pedals are among the most refined clipless mountain and gravel pedals available, designed for riders who value precise engagement, efficient power transfer, and low weight. However, achieving the perfect tension adjustment is essential for optimizing comfort, control, and performance. This guide explains how to correctly set up, adjust, and fine-tune the ATAC XC 12 [paid link] pedal tension for your riding style while maintaining smooth function and long-term durability.

Understanding the TIME ATAC XC 12 Pedal Design

The ATAC XC 12 uses TIME’s Auto Tension Adjustment Concept (ATAC) mechanism, which offers self-cleaning engagement and an adjustable release feel. Unlike many clipless systems, the ATAC mechanism uses a dual-arch retention spring that allows for lateral float and angular freedom. This design reduces knee strain while providing a solid platform for efficient pedaling.

The XC 12 model features:

A carbon body for stiffness and low weight.
Titanium axle for corrosion resistance and strength.
Adjustable release tension with two spring positions.
13° or 17° release angle options depending on cleat orientation.

Understanding these mechanical details is critical before making adjustments, as the ATAC system behaves differently from SPD or Look mechanisms.

Tools Required

4 mm hex key (for spring tension adjustment)
8 mm hex key (for pedal installation or removal)
Clean rag
Torque wrench [paid link] (recommended for reinstalling pedals)

Preparing for Adjustment

Before adjusting pedal tension, ensure that the pedals and cleats are clean. Dirt or debris in the spring mechanism can interfere with proper engagement and lead to inconsistent release force.

Remove the pedals if necessary and wipe them thoroughly.
Check cleat bolts for tightness (5 Nm recommended).
Inspect cleats for excessive wear, as worn cleats can affect release tension accuracy.

If your pedals feel stiff or inconsistent even when clean, inspect the spring pivot area for grime or oxidation and apply a light lubricant.

Locating the Tension Adjustment Mechanism

TIME’s ATAC XC 12 pedals have a two-position spring adjustment system rather than a continuous tension screw. Each pedal’s tension can be changed by rotating the retention spring with a 4 mm hex key.

Position 1: Standard tension (softer release feel, easier entry/exit).
Position 2: High tension (firmer release feel, improved stability).

The spring’s position is marked on the pedal body, and both sides must be adjusted evenly to maintain symmetrical engagement.

Adjusting the Pedal Tension

Follow these steps to set the desired release tension:

Insert the hex key into the small socket located on the pedal’s retention bar.
Turn the key carefully until you feel the spring click into the new position.
- Turning clockwise increases release tension.
- Turning counterclockwise decreases release tension.
Repeat on the opposite pedal to ensure identical release feel on both sides.
Test engagement and release using your cycling shoes. Step in firmly, twist out naturally, and note the effort required.

Make small adjustments as necessary and re-test after a short ride, since cleat orientation and shoe stiffness can affect perceived tension.

Finding the Ideal Tension Setting

The correct tension depends on your riding style and experience level [paid link]:

Beginner or gravel riders: Use the lighter spring position. It allows easier dismounts and reduces the risk of tipping over when stopping suddenly.
XC racers and aggressive riders: Opt for the firmer setting. This ensures secure engagement over rough terrain and during sprints.

TIME’s lateral float (±5°) and angular freedom (±2.5 mm) help protect joints even under high tension settings, so experienced riders can safely use the stiffer mode without knee strain.

Fine-Tuning the Release Feel

If the release still feels inconsistent after adjustment:

Clean and re-lubricate the engagement areas. TIME pedals rely on clean contact surfaces to maintain predictable release force.
Inspect cleats for deformation or rounding, especially around the wings. Replace if necessary.
Re-check cleat orientation. Flipping the cleats changes the release angle from 13° to 17°, which can affect tension perception.

Consistent cleaning and inspection ensure your chosen tension setting feels uniform and reliable during long rides.

Troubleshooting Common Tension Issues

Pedal Feels Too Tight Even on Low Setting

If engagement requires excessive force:

Verify that cleats are correctly oriented and free of dirt.
Apply a small amount of dry lube [paid link] to the spring and engagement surfaces.
Ensure the spring isn’t corroded or bent.

Pedal Feels Too Loose or Unstable

If your foot disengages too easily:

Move to the high-tension position.
Confirm that cleats aren’t excessively worn.
Check for play in the pedal body — worn bushings or bearings can create a “loose” feel that mimics low tension.

Uneven Engagement Between Left and Right Pedals

Always verify both pedals are set to the same spring position. Riders often overlook this, leading to inconsistent release force between sides.

Maintaining Proper Tension Over Time

Regular maintenance preserves the smooth function of the TIME ATAC XC 12’s retention system.

Clean after every ride, especially in muddy or sandy conditions.
Inspect spring arms monthly for damage or corrosion.
Lubricate lightly using a PTFE-based dry lube [paid link] to maintain smooth movement without attracting debris.
Check cleat bolts regularly for proper torque, as loose cleats alter engagement behavior.

When cleaned and maintained properly, the ATAC XC 12 pedals retain consistent release feel for thousands of riding hours.

Optimizing Performance Through Setup

Your pedal tension should complement your cleat angle and shoe fit. TIME’s generous float allows subtle movement that benefits joint comfort, but excessive float from worn cleats can feel vague. To optimize performance:

Use new cleats every 5,000–8,000 km or when the release becomes unpredictable.
Align cleats to match your natural foot angle.
Combine proper tension adjustment with consistent shoe placement for efficient power transfer and predictable release.

The result is a connected, confident ride whether you’re racing cross-country or tackling endurance gravel events.

Conclusion

Correct tension adjustment on TIME ATAC XC 12 pedals transforms how they feel underfoot. Setting them up properly enhances stability, improves power transfer, and prevents unwanted releases without sacrificing comfort. By understanding the ATAC mechanism, maintaining clean components, and making precise adjustments, you ensure your pedals perform flawlessly for years to come.

If noise occurs during clipping in or out, inspect your ATAC cleats [paid link] and engagement bars. Worn cleats or dry metal contact surfaces often cause clicking or squealing. Replace excessively worn cleats and lightly lubricate the bars with a dry-film lubricant to prevent contamination.

Internal Bearings or Bushings

A grinding or rattling sound that persists even when unclipped often indicates worn bearings or dry bushings. Over time, the pedal’s internal lubrication breaks down, allowing contaminants to enter. This condition requires a full bearing service or replacement.

Diagnosing Stiff ATAC XC 12 Pedals

Stiffness in pedal rotation or engagement typically results from contamination or internal wear.

Stiff Rotation Around the Spindle

If the pedal body doesn’t spin freely, the internal cartridge bearings or bushings may be dry or corroded. This happens when seals degrade or the pedal has been submerged repeatedly in water or mud. A full bearing overhaul is required to restore smooth motion.

Stiff Cleat Engagement

If clipping in feels unusually tight, debris inside the ATAC spring mechanism is often the cause. The design self-cleans to an extent, but compacted grit or dried mud can block the retention system. Remove the pedals, soak them briefly in warm soapy water, and clean the engagement area thoroughly using a soft brush. Avoid high-pressure washing, as this can push contaminants into the bearings.

Step-by-Step: Fixing Noisy or Stiff ATAC XC 12 Pedals

TIME ATAC XC 12 Pedal Set-Up Quality: Why It Feels Off and How to Fix It

Posted on ,

in No category

The TIME ATAC XC 12 [paid link] pedals are among the most precise and performance-driven options available for cross-country and gravel riders. Built with a carbon body and titanium spindle, they provide an exceptional stiffness-to-weight ratio and are known for their self-cleaning engagement mechanism. However, even a top-tier pedal like the ATAC XC 12 [paid link] can feel “off” if not installed or adjusted correctly. Issues such as uneven engagement, excessive play, or stiff release can all affect ride quality and efficiency. This guide explains why your ATAC XC 12 pedals might feel misaligned and provides detailed steps to correct and optimize their set-up.

Tools Required

8mm hex wrench (for installation/removal)
Torque wrench [paid link] with 8mm hex bit
Cleat alignment tool or marker
Thread grease or anti-seize compound
Pedal washer (if recommended for crank arm type)

Understanding TIME ATAC XC 12 Pedal Design

The ATAC (Auto Tension Adjustment Concept) system is unique to TIME pedals. It relies on a self-cleaning engagement design that allows for consistent cleat entry and release even in muddy conditions. Unlike traditional SPD systems, the ATAC mechanism uses an open arch design that provides float and angular freedom, reducing stress on the rider’s knees.

Each pedal offers 13° or 17° release angles, depending on how the cleats are mounted. The pedals have a fixed spring tension that’s factory-calibrated, meaning fine-tuning release force isn’t possible—but correct cleat orientation and installation torque play a critical role in how smooth the engagement feels.

When a set-up feels off, it’s usually due to one of three factors: incorrect cleat positioning, improper torque during installation, or wear on the cleats or pedal engagement bars.

Common Causes of Poor Set-Up Quality

1. Misaligned Cleats

If your cleats are rotated too far inward or outward, you’ll experience inconsistent engagement and uneven float. This can make one pedal feel stiffer than the other or cause your foot to rock during pedaling.

Cleats should align naturally with your foot position when clipped in. Riders with neutral biomechanics should start with cleats pointing straight ahead, then make micro-adjustments after short test rides.

2. Over-Tightened or Under-Tightened Pedals

Over-torquing the pedals into the crank arms can restrict the natural float mechanism of the ATAC design. Conversely, under-tightening can introduce play or creaking at the spindle interface. The correct torque specification is 25–30 Nm. Applying anti-seize compound to the threads before installation helps maintain proper torque and prevents corrosion.

3. Worn Cleats or Engagement Bars

TIME cleats are made of brass, which is softer than the stainless-steel bars on the pedals. Over time, the cleats wear down and can cause a loose or vague engagement feel. Similarly, if the pedal’s engagement bars develop grooves or burrs, entry and release can feel inconsistent. Regular inspection and replacement when wear is visible will restore smooth function.

4. Contaminated or Dry Spindle Bearings

Although the ATAC XC 12 uses sealed cartridge bearings and bushings, grime can build up around the spindle seal. This increases friction and leads to a rough or uneven pedal rotation. Cleaning and regreasing the spindle periodically will ensure a consistent feel.

Correcting an Off-Feeling Pedal Set-Up

Check Cleat Orientation

Remove the cleats from your shoes.
Reinstall them so that the arrow markings face forward and the release angle matches your preference (13° for quicker release, 17° for more stability).
Ensure both cleats are symmetrically aligned. Even a 1–2mm difference can create an uneven feel between pedals.

Re-Torque Pedals Correctly

Clean the crank arm threads thoroughly.
Apply a thin layer of grease or anti-seize compound.
Install the pedals using an 8mm hex wrench and tighten to 25–30 Nm.
Wipe away excess grease and test for play by rocking the pedal body laterally.

Inspect for Wear and Replace Components

If cleats appear rounded or the pedal’s bars are scored, replace the cleats first and re-test engagement. Persistent looseness may indicate internal bearing wear, requiring a rebuild kit or full replacement of the pedal body.

Clean and Lubricate the Spindle

Disassemble the pedal by removing the end cap and pulling the spindle. Clean all internal parts and apply a small amount of waterproof grease to the bearings and bushing. Reassemble carefully, ensuring the end cap is snug but not overtightened.

Fine-Tuning Engagement Feel

Although TIME’s ATAC XC 12 has a fixed spring tension, you can subtly influence engagement smoothness through cleat placement and pedal condition:

Forward-mounted cleats increase release force slightly and provide a more secure feel.
Rearward-mounted cleats make engagement easier, which benefits riders who frequently unclip in technical terrain.
Keep the pedal bodies clean and lightly lubricated with a dry-film lubricant to prevent mud or grit buildup.

Small refinements here can drastically change how natural and predictable your pedal engagement feels.

Performance Optimization Tips

Regularly clean pedals after muddy or wet rides to maintain the ATAC’s self-cleaning mechanism.
Replace cleats every 5,000–8,000 km or sooner if noticeable play develops.
Use a torque wrench [paid link] during every reinstallation to ensure consistent feel across both pedals.
If using carbon crank arms, check manufacturer recommendations regarding pedal washers to avoid damaging the crank interface.

When to Rebuild or Replace

The TIME ATAC XC 12 [paid link] is a high-end mountain and cyclocross pedal system designed for riders who demand lightweight performance, reliable engagement, and long-term durability. However, to unlock its full potential, understanding compatibility is crucial. This includes how the ATAC XC 12 [paid link] integrates with shoes, cleats, cranksets, and even bottom brackets. In this detailed guide, we’ll explore exactly what components work best, what to avoid, and how to ensure an optimal setup for efficiency and longevity.

Understanding the TIME ATAC XC 12 Pedal System

The ATAC XC 12 features TIME’s signature Auto Tension Adjustment Concept (ATAC), which provides consistent engagement regardless of riding conditions. With its carbon body, titanium axle, and hollow steel spring, the XC 12 delivers a balance of stiffness and lightweight construction ideal for cross-country and gravel racing.

However, unlike other clip-in systems, the ATAC interface is unique—meaning that not every shoe, cleat, or accessory is compatible. Knowing these differences can prevent poor engagement, uneven wear, or even premature pedal failure.

Shoe Compatibility: Getting the Interface Right

TIME’s ATAC cleats [paid link] are designed for two-bolt SPD-style shoes, but not all shoes offer a perfect fit. The cleat’s stack height and angular float mean that certain sole designs can interfere with entry or release.

Best Shoe Types for ATAC XC 12:

Cross-country (XC) racing shoes with rigid carbon or composite soles.
Gravel shoes with recessed cleat channels for easier walking and less debris interference.
Cyclocross shoes that offer ample clearance around the cleat pocket.

Shoes to Avoid:

Touring or commuting shoes with shallow cleat recesses—these may limit engagement.
Downhill or enduro shoes with aggressive tread patterns that can obstruct pedal entry.

For optimal performance, ensure the cleat pocket is deep enough for full pedal insertion, and that no tread material rubs against the pedal wings during engagement.

Cleat Compatibility: Genuine vs. Third-Party

TIME offers two main cleat models for the ATAC XC 12:

ATAC Easy Cleats – providing a 10° release angle for easier disengagement.
ATAC Standard Cleats – providing a 13° or 17° release angle depending on mounting orientation.

Both cleats are 100% compatible with the XC 12 pedal body. However, riders should avoid third-party cleats designed to mimic TIME’s design. These often use inferior materials, which can wear down the pedal’s retention mechanism and cause inconsistent float or engagement failures.

To maintain proper release tension and minimize wear, replace cleats after approximately 5,000–8,000 km or when engagement becomes noticeably loose.

Crankset and Q-Factor Compatibility

The ATAC XC 12 features a 52 mm Q-factor, which provides a natural pedaling stance for cross-country applications. When selecting cranksets, ensure that the pedal threads (9/16” x 20 TPI) are standard and that the crank arms provide sufficient clearance between the pedal body and the crank face.

Recommended Crank Arm Materials:

Carbon or forged aluminum crank arms with reinforced pedal inserts.
Avoid hollow aluminum designs with thin walls—especially on lightweight race cranksets—as excessive torque can damage the threads during installation.

If you’re using crank boots, confirm they do not interfere with pedal rotation. A small washer may be added between the crank and pedal if clearance is minimal.

Cleat Bolt and Shoe Plate Compatibility

TIME cleats use standard 2-bolt SPD-style screws (M5 x 10 mm), which are compatible with nearly all shoe mounting plates. However, certain high-end shoes (particularly those with custom or minimalist soles) may require longer screws or angled washers for proper torque distribution.

Improper screw length can cause two main issues:

Screws too short → Cleat movement or premature loosening.
Screws too long → Damage to the shoe’s insole or carbon sole layer.

Apply a medium-strength threadlocker such as Loctite 243 to the cleat bolts and torque them to 5–6 Nm for secure installation.

Chainstay and Frame Clearance

Due to its low-profile body and inward-facing spring design, the ATAC XC 12 offers excellent ground clearance. However, on some frames with wider chainstays or thicker crank arms, contact can occur when pedaling under load.

To check clearance:

Mount the pedals and rotate the crank backward.
Observe the pedal’s inward side for contact points.
Add pedal spacers (1–2 mm) if necessary to prevent rubbing.

Maintaining at least 2–3 mm of space between the pedal body and crank ensures smooth operation and prevents bearing wear from lateral stress.

Drivetrain Compatibility Considerations

The ATAC XC 12 pedal is fully compatible with any drivetrain system—Shimano, SRAM, Campagnolo, or others—since the interface is independent of the chainring or cassette. However, drivetrain efficiency indirectly affects pedal performance. A misaligned or contaminated drivetrain can create pedal feedback and vibration during high-torque efforts.

Regularly inspect and clean both the pedal and drivetrain to maintain smooth power transfer and consistent foot stability.

Cleat Positioning and Float Adjustment

TIME’s ATAC system provides 5° of angular float and 6 mm of lateral float, allowing natural knee movement and reducing strain during long rides. Proper cleat placement enhances comfort and efficiency.

Position the cleats so that:

The ball of the foot aligns directly over the pedal spindle.
The toes point naturally outward or inward based on your riding posture.
Lateral float is balanced between both pedals to prevent uneven wear.

Avoid setting both cleats at maximum float unless necessary for knee comfort. Excessive float can reduce stability and efficiency during sprints.

What to Avoid for Optimal Compatibility

While the ATAC XC 12 is versatile, several pitfalls can compromise its performance:

Mixing different generations of ATAC cleats [paid link] (e.g., older pre-2015 cleats may have fit issues).
Using SPD or Crankbrothers cleats, which are not compatible with TIME’s retention system.
Mounting cleats on worn or uneven shoe soles, which can distort engagement.
Applying grease inside the pedal mechanism—TIME pedals are designed to self-clean with mud clearance, and grease can trap debris.

Summary: Getting the Perfect Setup

The TIME ATAC XC 12 delivers elite-level [paid link] performance when set up correctly. Proper shoe and cleat pairing, crank clearance verification, and consistent maintenance are all essential for maximizing compatibility and lifespan. Riders who take the time to ensure precise alignment and component matching will benefit from the pedal’s lightweight feel, secure engagement, and long-term durability across all trail and race conditions.

Cleat Alignment and Engagement Setup

Proper cleat installation ensures efficient power transfer and prevents knee strain. The ATAC cleats [paid link] offer two release angle options—13° or 17°—depending on which cleat is mounted on which shoe. Position the cleats so that the ball of your foot aligns with the pedal spindle.

When clipping in, you should feel a positive click as the cleat engages the retention bars. If the engagement feels inconsistent or overly stiff, check for dirt buildup inside the mechanism. A quick clean and lubrication typically restore smooth entry and release.

Adjusting Spring Tension

The spring tension in the TIME ATAC XC 12 pedals can be fine-tuned to suit your riding preference. Using a small hex key, locate the adjustment screw on the outer edge of the pedal. Turning it clockwise increases release tension; turning it counterclockwise reduces it.

For riders new to the ATAC system, it’s best to begin with medium tension settings to find a comfortable balance between secure retention and easy release. Overly tight settings can lead to difficult disengagement during technical sections, while too loose a setting may cause unintended releases.

Routine Cleaning and Maintenance

To maintain top performance, clean your pedals after every few rides, especially in muddy or sandy environments. Use a brush and mild degreaser to remove debris from around the engagement mechanism. Avoid soaking the pedals, as water intrusion can reduce bearing life.

Once clean, apply a light coating of waterproof grease to the retention bars and cleat contact points. Wipe off any excess to prevent dirt accumulation.

Every 50–75 hours of riding, or after wet conditions, inspect the bearings for smooth rotation. If you detect grinding or stiffness, remove the end cap with needle-nose pliers, extract the axle, and clean the bearing area thoroughly. Apply fresh grease and reassemble carefully.

Servicing the Bearings

The TIME ATAC XC 12 pedals use sealed cartridge bearings and bushings that require occasional lubrication but rarely need full replacement. If play develops between the axle and body, it’s a sign the bushings are wearing out.

Disassemble the pedal by removing the end cap and sliding the axle out. Clean all parts and inspect for wear. Apply high-quality bearing grease before reinstalling. Torque the end cap to specification and ensure there’s no side-to-side movement.

This simple routine extends the service life of your pedal bearings significantly.

The TIME ATAC XC 12 [paid link] pedals are high-end cross-country and gravel clipless pedals designed for maximum efficiency, low weight, and superior mud-shedding performance. Built with carbon body construction and titanium axles, they deliver exceptional stiffness-to-weight ratio and long-term durability. However, incorrect installation or poor setup can significantly affect their performance, engagement reliability, and lifespan. This guide explains the most common installation mistakes riders make with the ATAC XC 12 [paid link], how to avoid them, and the proper method to ensure optimal pedal function from day one.

Tools Required

8 mm hex wrench
Torque wrench [paid link] (capable of measuring 20–40 Nm)
Grease (suitable for titanium or carbon interfaces)
Threadlocker (medium strength, optional)
Clean rag

Understanding the ATAC XC 12 Design

The TIME ATAC XC 12 features a self-cleaning retention system, allowing easy entry even in muddy or gritty conditions. Its ATAC (Auto Tension Adjustment Concept) mechanism provides consistent engagement and release tension, minimizing the need for frequent adjustments. The pedals use a titanium axle, requiring careful torque management to avoid thread damage, and a carbon composite body that must be handled gently during installation to prevent cracking.

Because of these premium materials, correct installation torque, alignment, and lubrication are crucial for ensuring long-term reliability and consistent power transfer.

Mistake 1: Installing Without Proper Grease on the Threads

One of the most common errors is installing the ATAC XC 12 pedals without applying sufficient grease to the spindle threads. Titanium and aluminum (often used in crank arms) are prone to galling, a form of cold welding that can permanently seize the threads.

Always apply a thin, even layer of anti-seize compound or high-quality grease to the pedal threads before installation. This prevents corrosion and ensures the pedals can be removed smoothly for maintenance. Avoid using dry threads, as they can creak under load and cause premature wear on the crank interface.

Mistake 2: Over-Tightening the Pedal Spindles

Over-tightening is another critical mistake that can cause damage. The recommended installation torque for TIME ATAC XC 12 pedals is typically between 30–35 Nm. Exceeding this range can strip crank arm threads, especially if made from lightweight materials such as carbon or forged aluminum.

Using a torque wrench [paid link] ensures consistent installation pressure. Tighten until you reach the specified torque and confirm the pedal is seated flush with the crank arm face. Over-torqueing can also distort the spindle bearings, leading to premature roughness or binding.

Mistake 3: Cross-Threading During Installation

Because of the fine threading on titanium spindles, cross-threading is a risk if the pedal is not aligned correctly with the crank arm. Always start threading by hand, ensuring smooth engagement before applying the torque wrench. If resistance is felt within the first few turns, stop immediately and realign the threads.

Cross-threading can irreparably damage both the crank arm and the pedal spindle, often requiring crank replacement. Proper initial alignment ensures a secure and precise fit.

Mistake 4: Installing Pedals on the Wrong Side

Although it may seem basic, installing the pedals on the wrong side—left pedal on the right crank or vice versa—is a surprisingly common mistake. The left pedal uses reverse threading (tightens counterclockwise), while the right pedal tightens clockwise. This design prevents the pedals from loosening during pedaling motion.

Always check for the small “L” or “R” markings near the spindle base before installation. Installing on the incorrect side can damage the threads within a few pedal strokes and may void warranty coverage.

Mistake 5: Neglecting Cleat Alignment During Installation

The ATAC XC 12 relies on precise cleat alignment for optimal engagement. Misaligned cleats can cause premature release, difficulty clipping in, or inconsistent float behavior. TIME cleats offer 13° or 17° release angles, depending on orientation during mounting.

Ensure that the cleats are installed according to your preferred release angle, centered under the ball of the foot, and parallel to the shoe’s longitudinal axis. Poor alignment increases knee strain and can lead to uneven wear on the engagement surfaces.

Mistake 6: Skipping the Threadlocker Step (When Recommended)

TIME generally recommends using a medium-strength threadlocker on the pedal threads for riders who frequently ride in wet or muddy environments. This prevents the pedals from loosening under vibration and torque stress. However, threadlocker should never replace grease; it should only be applied sparingly over the lubricated surface.

Neglecting this step can lead to minor rotational movement between the spindle and crank arm, resulting in creaking noises and gradual wear.

Mistake 7: Ignoring Bearing Preload or Play

After installation, check for bearing play or stiffness by rotating each pedal spindle by hand. A properly installed ATAC XC 12 pedal should spin freely but not feel loose. If the pedal binds or grinds, it may indicate internal bearing compression from over-tightening. Conversely, noticeable side-to-side play could mean the pedal isn’t fully seated.

TIME’s sealed cartridge bearings require minimal user adjustment, but excessive play should be addressed immediately to prevent premature bearing failure.

Mistake 8: Using Incompatible Cleats

Only use genuine TIME ATAC cleats [paid link] with the XC 12 pedals. Third-party cleats or worn-out cleats can affect engagement depth and release force. TIME cleats are made of brass for smooth engagement and designed to wear before the pedal mechanism, protecting the pedal body.

Mixing incompatible cleats often results in a “sloppy” connection or difficulty clipping in under power, which can compromise safety during aggressive riding.

Mistake 9: Neglecting Post-Installation Recheck

After your first few rides, it’s essential to recheck pedal tightness and cleat alignment. Pedal threads can settle slightly under load, particularly after the first 50 km of riding. Re-torque the pedals to specification and inspect for any unusual noises or changes in engagement feel. This step ensures the assembly remains stable and secure over time.

Conclusion

The TIME ATAC XC 12 pedals are precision-engineered components that reward careful installation and maintenance with exceptional performance and durability. By avoiding these common mistakes—such as neglecting lubrication, over-torqueing, cross-threading, or misaligning cleats—you’ll preserve the pedal’s engagement quality, reduce wear, and prevent costly damage. When properly installed, the ATAC XC 12 delivers flawless engagement, superior mud clearance, and one of the most efficient power transfers in the cross-country pedal market.

The Shimano XTR M9100, in contrast, uses an aluminum body with a chromoly spindle, weighing slightly more at about 310 grams per pair.

While the ATAC prioritizes weight savings and float range, Shimano’s design leans toward robustness and consistent engagement in all conditions. Riders seeking a minimalist yet responsive pedal will appreciate TIME’s carbon-titanium construction, whereas those valuing durability and mechanical precision might prefer the heavier, metal-based XTR body.

Engagement Mechanism and Cleat Interface

The most noticeable difference between the two pedals lies in their engagement systems. TIME’s Auto Tension Adjustment Concept (ATAC) provides self-cleaning capabilities that shed mud and debris as the cleat engages. This design makes the ATAC XC 12 particularly effective in muddy or dusty race environments. The spring mechanism requires minimal effort to clip in and offers 13° or 17° of float, depending on cleat orientation.

Shimano’s SPD mechanism delivers a firmer, more mechanical engagement. Riders often describe it as more secure but slightly less forgiving under lateral foot movement. The XTR M9100 provides adjustable tension, allowing riders to fine-tune the release feel, but it requires more frequent cleaning to maintain consistent performance in muddy conditions.

For riders who prefer natural float and easy engagement, TIME has the advantage. For those prioritizing positive retention and precision release, Shimano’s SPD remains the benchmark.

Bearing System and Maintenance

Both pedals utilize sealed cartridge bearings, but TIME’s internal design offers a maintenance edge. The ATAC XC 12 uses needle and cartridge bearings that are factory-sealed, reducing contamination risk and extending service intervals. Shimano’s bearings, while durable, benefit from periodic regreasing due to their more open design.

TIME’s sealed configuration ensures a longer lifespan with less intervention, ideal for racers who prefer a set-and-forget component. Shimano’s system allows for easier user serviceability, which appeals to riders who enjoy performing regular maintenance.

Float and Biomechanical Efficiency

TIME is known for its generous float, which plays a significant role in rider comfort and joint health. The ATAC XC 12 offers 5mm of lateral float and a rotational float of up to 17°, depending on cleat setup. This allows a more natural foot motion throughout the pedal stroke and can reduce knee strain during long rides.

Shimano’s SPD system provides less float—typically 4° to 6° rotational—which enhances power transfer but may feel restrictive for riders with sensitive knees. Racers who value maximum biomechanical freedom will find TIME’s float geometry advantageous, while those focused on power efficiency and sprinting response might lean toward the XTR’s fixed feel.

Pedal Platform and Shoe Interface

The ATAC XC 12 has a smaller contact area than the Shimano XTR, relying on its dual-arch engagement bars to stabilize the shoe. However, the carbon body still distributes pressure evenly when used with stiff-soled cross-country shoes.

Shimano’s XTR M9100 incorporates a broader platform that increases shoe-to-pedal contact. This design translates to better energy transfer, particularly noticeable on out-of-saddle climbs and accelerations. Riders who prioritize stiffness and support may appreciate the XTR’s larger contact surface, while those who favor a lighter, more flexible ride feel may prefer the ATAC XC 12.

Durability and Long-Term Reliability

In terms of durability, both pedals perform exceptionally well, but their longevity depends on riding environment and care. The ATAC XC 12’s titanium axle is resistant to corrosion and wear, but the carbon body can show cosmetic damage from rock strikes. Shimano’s all-metal construction withstands abuse better in rocky or technical terrain.

That said, the ATAC’s self-cleaning mechanism offers a clear advantage for riders in muddy or wet conditions. Shimano’s SPD design can pack with debris, occasionally requiring manual cleaning. For endurance riders who frequently face variable terrain, the ATAC XC 12 provides a more consistent engagement experience.

Customization and Adjustability

TIME’s approach to customization is minimal but effective. The cleat orientation determines both the float angle and release direction, giving riders a simple way to tailor engagement to their preference. Shimano, on the other hand, provides tension adjustment screws that allow fine-tuning of entry and release forces—useful for riders who switch between racing and training setups.

If you prefer set-and-ride simplicity, the ATAC system excels. If you want precise control over release tension, Shimano’s SPD is superior.

Compatibility with Shoes and Cleats

The ATAC XC 12 uses TIME’s proprietary ATAC cleats [paid link], which are compatible with most two-bolt MTB shoes. However, they are not cross-compatible with SPD cleats or pedals. The Shimano XTR M9100 uses SPD cleats, which are widely available and compatible with numerous third-party pedal systems.

Riders who prioritize availability and interchangeability may find Shimano’s SPD ecosystem more convenient. Those committed to TIME’s unique float and engagement characteristics will find the ATAC cleats [paid link] a worthwhile trade-off.
