The TIME ATAC XC 12 [paid link] pedals are known for their lightweight construction, excellent mud-shedding ability, and precise engagement mechanism, making them a top choice among cross-country and gravel riders. However, as technology evolves, riders often wonder whether they can upgrade their ATAC XC 12 [paid link] pedals to further enhance performance, durability, or feel. This guide explores the available upgrade paths, compatibility considerations, and best practices for achieving optimal performance from your ATAC XC 12 pedals.
Understanding the TIME ATAC XC 12 Pedal Design
The ATAC XC 12 pedals are constructed around a carbon body with titanium axles, which gives them an impressive combination of stiffness and minimal weight (around 248 grams per pair). The design incorporates the ATAC (Auto Tension Adjustment Concept) mechanism—an open engagement system that clears mud and debris efficiently while maintaining reliable cleat retention.
Internally, the pedal relies on sealed cartridge bearings and bushings to minimize friction and resist contamination. The cleat system uses TIME’s proprietary two-bolt interface, offering a range of float and release angle adjustments depending on the cleat orientation.
Because of these design features, any upgrade must maintain compatibility with both the ATAC system and the pedal’s internal tolerances.
Possible Upgrades for TIME ATAC XC 12 Pedals
While the ATAC XC 12 is already at the top of TIME’s XC range, several performance and longevity improvements are still possible through targeted component upgrades and maintenance practices.
1. Bearing and Bushing Replacement
Replacing worn bearings and bushings is the most practical and impactful upgrade for these pedals. Over time, the pedal’s smooth rotation can degrade due to contamination or bearing wear. TIME offers factory service kits containing replacement bearings, bushings, and seals specifically designed for the ATAC XC 12.
Upgrading to high-precision stainless steel or ceramic hybrid bearings can further reduce rotational resistance and extend service life. Ensure that the bearing dimensions match TIME’s specifications to prevent internal binding or premature wear.
2. Cleat System Upgrade
TIME provides several cleat options compatible with the ATAC system, each with distinct float and release characteristics. Riders can choose between:
- ATAC Easy Cleats (10° release angle): Easier engagement and disengagement, ideal for beginners or riders seeking convenience.
- ATAC Standard Cleats (13° or 17° release angle): Greater control for technical riding and racing conditions.
Switching cleats can significantly alter pedal feel and release behavior, effectively functioning as a performance upgrade without altering the pedals themselves.
3. Axle and Spindle Upgrades
The XC 12 already features titanium axles, which are both strong and lightweight. For riders using lower-tier ATAC models (XC 6, 8, or 10), upgrading to the titanium spindles found in the XC 12 is possible, provided spindle dimensions and thread compatibility are identical.
However, for XC 12 owners, replacing the titanium axles is typically unnecessary unless damage or excessive flex develops over time. Always apply a high-quality anti-seize compound during axle installation to prevent galvanic corrosion between titanium and steel components.
4. Customization via Cleat Shims and Shoe Interface
Optimizing the shoe-to-pedal interface can transform the pedaling experience. Cleat shims or spacers can adjust the stack height and engagement consistency across different shoe soles. Proper alignment reduces stress on the knees and ankles while improving power transfer.
TIME’s ATAC system is inherently forgiving, but fine-tuning cleat placement can enhance comfort and minimize hot spots during long rides.
Compatibility Considerations for Upgrading
Before performing any upgrade, it’s essential to verify compatibility with the ATAC engagement system. The following key points ensure that modifications enhance rather than compromise performance:
- Cleat Compatibility: Only TIME ATAC cleats [paid link] fit ATAC XC pedals. Using other two-bolt cleats, such as SPD or Crankbrothers, is not compatible.
- Bearing Dimensions: Replacement bearings must match original dimensions and load ratings to preserve the pedal’s internal clearances.
- Axle Fitment: Spindles from lower-tier ATAC models can fit if the pedal body and bearing interface match precisely.
- Pedal Body Integrity: Avoid replacing the carbon body or machining the engagement mechanism, as this compromises the structural integrity and voids warranty coverage.
Optimization Practices for Enhanced Performance
Even without major hardware upgrades, several optimization techniques can keep ATAC XC 12 pedals performing like new.
Regular Cleaning and Lubrication
Dirt accumulation around the engagement mechanism can cause stiff entry or inconsistent release. Clean the pedals after every few rides using mild soap and water, then apply a small amount of dry-film lubricant around the spring mechanism.
Bearing Service Intervals
TIME recommends servicing bearings every 3,000–5,000 km under normal conditions. In wet or muddy environments, reduce this interval to maintain smooth rotation and prevent corrosion.
Torque and Thread Inspection
Ensure the pedal threads are torqued to 35–40 Nm when installed into the crank arm. Over-tightening can deform the threads, while under-tightening can lead to creaking or movement under load.
Comparing Upgrades: XC 12 vs. XC 10 and XC 8
The ATAC XC 12 stands out due to its titanium spindle and carbon body, while lower-tier models such as the XC 10 use a carbon-filled composite body and steel spindle. Functionally, all ATAC pedals share the same engagement system, meaning performance differences mainly stem from weight and material stiffness.
If upgrading from XC 8 or XC 10 pedals, the XC 12 offers tangible benefits: reduced weight, smoother engagement, and better long-term resistance to flex. However, the reverse—upgrading within the XC 12 platform—yields diminishing returns unless focusing on bearings or cleats.
When Upgrading Is Not Recommended
Certain modifications may seem tempting but should be avoided to maintain performance and reliability:
- Non-OEM Springs or Retention Bars: Altering spring tension beyond factory specifications can compromise cleat engagement and cause premature wear.
- Third-Party Bearings or Bushings Without Matching Tolerances: Small dimensional differences can cause binding or uneven rotation.
- Body Modifications or Aftermarket Carbon Repairs: These can severely weaken the structure and lead to catastrophic failure.
Staying within the manufacturer’s service guidelines ensures both safety and longevity.
Best Practices for Long-Term Pedal Performance
- Inspect cleats regularly for rounding or burr formation; replace as soon as engagement feels inconsistent.
- Reapply grease to the axle threads and pedal bearings during each service cycle.
- Store the bike indoors to prevent condensation and corrosion in the bearing assembly.
- Avoid using high-pressure water directly on the pedal body during cleaning.
Conclusion
Upgrading the TIME ATAC XC 12 pedals is both possible and worthwhile when done strategically. The most effective improvements come from precision bearing replacements, cleat upgrades, and consistent maintenance rather than structural modifications. With careful attention to compatibility and correct servicing intervals, the ATAC XC 12 can continue delivering exceptional performance for thousands of kilometers—remaining one of the most refined and efficient off-road pedal systems available.
