The TIME ATAC XC 2[paid link] is a popular choice among cross-country and gravel riders for its reliable engagement, self-cleaning design, and light composite body. However, even with a proven system like the ATAC mechanism, improper installation or maintenance can cause the pedals to feel “off.” Symptoms such as vague engagement, uneven tension, or premature bearing play often result from set-up inconsistencies rather than design flaws. This guide explains how to correctly install, inspect, and optimize your TIME ATAC XC 2[paid link] pedals for smooth, precise performance.
Understanding the TIME ATAC XC 2 Pedal System
The ATAC (Auto Tension Adjustment Concept) mechanism is a self-cleaning system that uses lateral float and angular freedom to promote natural knee alignment. The XC 2 model features a composite body, steel axle, and a spring-retained engagement bar system. Its tension is fixed, but float characteristics and stack height depend heavily on installation accuracy and cleat condition. When the set-up feels off, the issue often lies in the interface between shoe, cleat, and spindle alignment.

- Grease or anti-seize compound
- Clean rag
- Pedal wrench[paid link] (optional for removal)
- Cleat alignment tool (optional but recommended)
Common Signs of Poor ATAC XC 2 Set-Up
A misaligned or poorly installed pedal set can exhibit several symptoms. Riders may notice excessive side-to-side movement, difficult engagement, or uneven float resistance. A common complaint is that one side clips in smoothly while the other side resists or releases prematurely. Additionally, bearing noise or spindle play under load may suggest improper torque or contamination. These issues can reduce confidence in technical terrain and lead to uneven cleat wear.
Correct Pedal Installation Procedure
Before diagnosing set-up quality, it’s essential to confirm that installation was performed to specification. Begin by cleaning the crank threads thoroughly. Apply a thin film of grease or anti-seize to the pedal threads. Thread the pedals into the crank arms by hand, ensuring they engage cleanly without cross-threading. Tighten each pedal using an 8 mm hex key to 30–35 Nm of torque. Over-tightening can damage crank threads, while under-tightening allows micro-movement that leads to creaks and misalignment.
Cleat Position and Its Impact on Set-Up Quality
The TIME ATAC cleats[paid link] are directional, and their orientation controls float characteristics and release angle. When installed incorrectly, they can make engagement feel inconsistent. Position the cleats symmetrically on both shoes with the arrow pointing forward. Ensure the cleats are centered along the shoe’s longitudinal axis and tightened evenly. If one cleat is rotated slightly more than the other, the rider may experience asymmetrical float or uneven release effort, causing one pedal to “feel off.”
Inspecting Pedal and Cleat Interface
The ATAC system depends on a clean and properly shaped cleat for reliable engagement. Dirt, grit, or wear can make the pedal feel vague or imprecise. Inspect the cleat surface for rounded edges or deep grooves, especially where the spring bar interfaces. If the cleats show significant wear, replace them immediately. Clean the pedal body and spring mechanism with a damp rag. Avoid harsh solvents, which can damage the composite body. Apply a small amount of dry lubricant to the spring bar area to maintain smooth entry and release.
Assessing Bearing Condition and Axle Play
A loose or gritty bearing can make the ATAC XC 2 feel imbalanced, even if engagement is correct. Check for side-to-side play by wiggling the pedal body against the spindle. Any perceptible movement indicates bearing wear or loose end caps. The XC 2 uses a sealed bearing system that is not user-serviceable, but periodic cleaning and lubrication around the spindle interface can extend life. If excessive play persists, replacement of the pedal or bearing unit is necessary to restore proper feel.
Troubleshooting Uneven Engagement
If one side of the pedal engages differently, it often results from debris trapped under the spring or a bent engagement bar. Clean the spring area thoroughly using compressed air or a soft brush. Check for any deformation along the bar; even minor bends can alter tension. Another potential cause is shoe sole interference. Thick tread patterns can prevent full cleat engagement, particularly on gravel or MTB shoes. Trim the tread slightly around the cleat pocket to improve consistency.
Optimizing Shoe Compatibility for Better Feel
TIME ATAC pedals work best with shoes that have a stiff sole and a recessed cleat pocket. Flexible soles can cause a spongy feeling during engagement. To achieve the best set-up, use a shoe that supports the cleat evenly across the interface. If the shoe’s tread sits too high, consider adding shims under the cleats. This adjustment ensures consistent float and reduces premature wear on both pedal and cleat.
Checking Float and Release Consistency
The ATAC system provides 13° or 17° release options depending on cleat orientation. Riders who feel that float or release is inconsistent should confirm that both cleats are mounted in identical orientations. If one cleat is reversed, it will release at a different angle. Also, check that the spring tension feels balanced between the left and right pedals. A noticeable difference could indicate a worn or damaged spring, which may require replacement.
When the Set-Up Feels Too Loose
A loose or unstable feel typically means the cleats have worn beyond tolerance. Since TIME cleats are made of brass, they wear faster than steel alternatives, which helps preserve the pedal body but shortens service life. If the pedals feel sloppy even after cleaning and alignment, replace the cleats. Always recheck the shoe-to-cleat torque after the first few rides, as brass can settle slightly into the shoe sole.
Restoring Factory Smoothness
To restore the original pedal feel, perform a full cleaning and lubrication routine every few weeks. Remove the pedals, clean the spindle interface, and re-grease the threads. Wipe down the engagement mechanism and reapply a light coat of dry lube. These simple steps eliminate the gritty or vague feeling that often develops after wet or dusty rides. Consistent maintenance not only improves feel but also extends the lifespan of the pedals.
Conclusion
When your TIME ATAC XC 2 pedals feel “off,” the problem rarely lies in the design. Instead, it stems from small inconsistencies in installation, cleat alignment, or bearing condition. By following proper torque specifications, ensuring clean engagement interfaces, and maintaining cleat symmetry, you can restore precise engagement and confident float. The ATAC system rewards careful setup with reliable performance, smooth release, and long-term durability across countless miles of off-road riding.
