The TIME ATAC XC 8 [paid link] pedals are a top-tier choice for cross-country and gravel riders who demand a reliable, lightweight, and mud-shedding clip-in system. However, even the most precise component can underperform if not installed or adjusted correctly. Incorrect setup is one of the most common causes of poor engagement, premature wear, and discomfort during rides. This guide will help you identify setup issues specific to the TIME ATAC XC 8 [paid link] model and teach you how to fix them effectively for optimal performance.
Tools Required
- 8mm hex wrench
- Torque wrench [paid link]
- Pedal grease
- Clean rag
- Medium-strength threadlocker (optional)
Understanding the TIME ATAC XC 8 Pedal System
The TIME ATAC XC 8 pedal uses a dual-arch engagement system with self-cleaning properties. This design provides easy entry and release, even in muddy conditions. The ATAC (Auto Tension Adjustment Concept) mechanism allows a natural range of lateral and angular float, reducing strain on knees and improving comfort on long rides.
However, proper installation and cleat orientation are critical to achieving the pedal’s intended feel. A misaligned cleat or overtightened installation can result in uneven engagement, stiffness, or unwanted float play.
Incorrect Installation: The Most Common Setup Problem
Improper installation is the root of many issues with the ATAC XC 8. Since the pedal body is made from a composite material with a hollow steel axle, overtightening can distort the interface or damage threads. Conversely, under-tightening can cause creaking or side-to-side play.
Always install the pedals using an 8mm hex key on the inside of the crank arm. Apply a thin layer of grease on the threads to prevent seizing. Tighten the pedal to 35–40 Nm of torque.
If the pedal threads are dry or cross-threaded, it can lead to binding and cause the pedal to feel rough or resist free rotation. In this case, remove the pedal, inspect the crank arm threads, and reinstall with the proper lubrication.
Cleat Alignment and Float Issues
The ATAC cleats [paid link] supplied with the XC 8 pedals allow 13° or 17° release angles, depending on which shoe is fitted with which cleat. Installing the cleats in the wrong orientation can cause difficulty in disengaging or excessive float.
Ensure that:
- The cleat markings are facing forward and centered relative to the shoe sole.
- Both shoes have symmetrical alignment unless a different release angle is desired.
- The cleats are torqued evenly and checked after the first few rides, as they can loosen slightly due to sole compression.
A cleat that is misaligned or not flush with the shoe can cause uneven engagement. Riders often report one pedal feeling “softer” or “stickier” than the other—this is almost always due to a mismatched cleat angle.
Engagement and Release Tension Problems
Unlike many clip-in systems, the ATAC XC 8 does not use an adjustable tension spring. Instead, tension is determined by the internal spring stiffness and cleat interface condition. If engagement feels excessively tight or loose, inspect the cleat wear and spring tension bars.
Common issues include:
- Worn cleats: Excessive rounding of the cleat edges can cause loose engagement. Replace cleats if they show visible wear or corrosion.
- Mud or debris buildup: The ATAC’s open design resists clogging, but compacted dirt can still limit float movement. Clean both cleats and pedal springs with a soft brush and warm water.
- Deformed springs: If the spring bars appear bent or uneven, they may need replacement. This requires a pedal service kit and precise reassembly to maintain correct tension.
Pedal Body Misalignment
Another reason your ATAC XC 8 pedals might not feel right is pedal body misalignment caused by an uneven spindle interface. If the pedal doesn’t spin freely, check that the inner bushing and outer cartridge bearing are functioning correctly.
A common sign of internal misalignment is a grinding sensation when rotating the spindle by hand. To fix this:
- Remove the pedal from the crank.
- Using a thin 6mm hex key, access the spindle assembly and check for play.
- Re-grease the bearings and reassemble with the correct torque.
If play persists, the bearing cartridge may be worn and should be replaced with an OEM service part.
Common Setup Errors That Affect Performance
- Pedals Installed Backward: Installing left and right pedals on the wrong sides can strip the crank threads. The left pedal has reverse threading—tighten it counterclockwise.
- Cleats Too Far Forward: This shifts pressure to the ball of the foot and reduces stability. Move the cleat slightly rearward to balance weight distribution.
- Inconsistent Torque: Uneven tightening across both pedals can create asymmetric feel. Always verify torque with a wrench.
- No Grease Used on Threads: This leads to corrosion and difficult removal. A light grease coat ensures longevity and smoother pedaling.
Diagnosing Pedal Feel: Stiff vs. Loose
If your ATAC XC 8 pedals feel stiff when clipping in, debris or a dry engagement spring may be the cause. Apply a small amount of dry Teflon lubricant to the engagement bars. For a loose feeling, inspect the cleat retention area for wear.
Sometimes, a “loose” sensation can be mistaken for lateral float, which is actually a feature of the ATAC system. Riders transitioning from SPD systems often perceive this as instability, but it’s intentional for improved knee comfort.
Optimizing Setup for Performance
To achieve the best pedal feel:
- Keep cleats clean and lightly lubricated.
- Check cleat bolt torque every 100 km.
- Service pedal bearings every 3,000–5,000 km.
- Replace cleats every 6–12 months, depending on riding frequency.
Correctly set up ATAC XC 8 pedals deliver smooth engagement, excellent float, and minimal maintenance requirements. By keeping both pedal and cleat interfaces aligned and clean, you ensure reliable performance even in adverse conditions.
Conclusion
When TIME ATAC XC 8 pedals don’t feel right, the cause almost always traces back to improper setup, worn cleats, or incorrect torque. By following the correct installation procedure and ensuring proper alignment, you can eliminate most engagement or float issues. Regular maintenance—cleaning, greasing, and timely cleat replacement—keeps these high-performance pedals operating flawlessly for thousands of kilometers.
A precisely set up pair of TIME ATAC XC 8 pedals transforms your ride, offering dependable engagement, smooth float, and the efficiency expected from a professional-grade component.
