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.

  1. Remove the pedals if necessary and wipe them thoroughly.
  2. Check cleat bolts for tightness (5 Nm recommended).
  3. 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:

  1. Insert the hex key into the small socket located on the pedal’s retention bar.
  2. Turn the key carefully until you feel the spring click into the new position.
    • Turning clockwise increases release tension.
    • Turning counterclockwise decreases release tension.
  3. Repeat on the opposite pedal to ensure identical release feel on both sides.
  4. 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.
