The TIME ATAC XC 2[paid link] pedals are well-regarded for their reliability, mud-clearing design, and consistent engagement performance. However, to truly benefit from their potential, the tension adjustment must be correctly set. Proper adjustment ensures efficient power transfer, predictable float movement, and easy engagement and release. This guide explains how to adjust the spring tension on the ATAC XC 2[paid link] pedals, troubleshoot common tension issues, and fine-tune them for optimal performance on various terrains.
Understanding the ATAC XC 2 Tension System
The ATAC (Auto Tension Adjustment Concept) mechanism is one of TIME’s key innovations. Unlike many SPD-style systems that require manual spring tension adjustment, the ATAC system provides self-cleaning, automatic engagement with a preset spring tension designed for cross-country and gravel performance. Although the XC 2 pedals do not feature an external tension adjustment screw like higher-end models, their float and release angle can be optimized through cleat orientation and maintenance.
The pedal’s steel retention bars flex to allow engagement and disengagement, and the cleat’s orientation determines both the release angle and effective tension feel. There are two cleat mount positions available, offering either a 13° or 17° release angle, depending on rider preference.
Tools Required
- 8 mm hex key
- Torque wrench[paid link] (optional but recommended)
- Grease or assembly compound
- Clean rag
- TIME ATAC cleats[paid link] (for cleat adjustment)
Step 1: Inspect the Pedals and Cleats
Before making any adjustments, inspect both the pedal body and cleats for wear. Excessive play or worn bars can mimic low tension and make engagement feel inconsistent. Likewise, worn cleats can lead to a “loose” connection even if the system itself is in good condition.
Clean the pedals thoroughly using a rag and a mild degreaser if necessary. Ensure the retention bars move freely without debris or corrosion.
Step 2: Set Cleat Orientation to Adjust Release Angle and Tension Feel
The cleat orientation on the ATAC XC 2 directly affects both release characteristics and perceived tension:
- Standard orientation (13° release): Easier to disengage, suitable for beginners or riders who prefer quick exits.
- Reversed orientation (17° release): Harder to disengage, providing a more secure fit for aggressive riders or technical terrain.
To change this:
- Remove the cleat bolts from the shoe sole using a 4 mm hex key.
- Flip the cleat to the opposite shoe or rotate 180°, depending on your desired release setting.
- Reinstall and torque the bolts evenly (typically 5–6 Nm).
- Verify that the cleats are symmetrical on both shoes.
This small adjustment effectively alters the retention feel of the pedal, simulating higher or lower tension without physically modifying the spring system.
Step 3: Check Engagement and Float
Clip in and out of the pedals while stationary to feel the engagement pressure. The ATAC system naturally provides angular and lateral float—approximately 5 mm of lateral movement and 10° of angular float. This movement allows your knees to align naturally during pedaling.
If the float feels too free or inconsistent, inspect the cleat wear or contamination around the pedal spring area. Dirt accumulation can reduce spring movement, making the tension feel artificially high. A quick cleaning and re-greasing of the retention bars usually restores smooth function.
Step 4: Re-Grease Pedal Axle and Retention Bars
Smooth operation also depends on clean, lubricated internals. To maintain consistent tension:
- Remove the pedal from the crank arm using an 8 mm hex key.
- Apply a light coat of grease to the threads and reinstall.
- Use a small brush or cotton swab to apply a thin layer of waterproof grease to the spring and retention bar area.
- Avoid over-lubricating—excess grease can attract dirt and increase friction over time.
This process ensures that the pedal’s internal return spring operates freely, maintaining the correct self-adjusting tension profile.
Step 5: Test Ride and Fine-Tune
After reinstallation, take a short test ride. Focus on:
- Engagement consistency
- Release smoothness
- Float freedom
If you experience inconsistent engagement or unexpected release, double-check cleat bolt torque and orientation. Sometimes, shoes with uneven soles or flexible midsoles can slightly misalign the cleat angle, causing perceived tension variations.
For best performance, inspect the pedals and cleats every 20–30 hours of riding, especially after muddy or dusty conditions. The ATAC system relies heavily on mechanical precision and cleanliness for accurate tension feel.
Common Tension-Related Issues and Fixes
1. Pedals feel too tight:
Clean and lightly grease the spring area. Check for mud or rust buildup. Confirm that cleats are installed in the 13° release configuration.
2. Pedals feel too loose:
Inspect cleats for wear. Reposition to the 17° release configuration for increased retention. Ensure no excessive play exists between the cleat and pedal interface.
3. Inconsistent release between left and right pedals:
Compare cleat wear between shoes. Uneven wear often causes one side to release more easily. Replace cleats in pairs for consistent feel.
4. Creaking or stiffness when engaging:
Remove pedals, clean axle threads, and re-grease. Apply a small amount of lubricant to the retention bars to reduce noise.
Maintenance Recommendations
To keep your TIME ATAC XC 2 pedals performing at their best:
- Clean pedals after every ride, especially in muddy conditions.
- Inspect cleats monthly for rounding or distortion.
- Replace cleats every 3,000–5,000 km, depending on terrain and weather exposure.
- Apply fresh grease to the spring mechanism quarterly to prevent corrosion and maintain proper spring tension.
Consistent maintenance not only preserves the pedal’s self-cleaning function but also ensures that the automatic tension adjustment continues to perform as designed.
Conclusion
Although the TIME ATAC XC 2 pedals lack a manual tension adjustment screw, they deliver a finely tuned balance of security and ease through their cleat orientation and self-regulating spring system. By maintaining clean interfaces, properly oriented cleats, and well-greased mechanisms, riders can achieve ideal tension that suits both technical and endurance riding styles. Regular inspection and servicing will ensure that every clip-in feels consistent and every release is predictable—exactly as the ATAC design intends.
