Installing clipless pedals like the TIME ATAC XC 2 [paid link] can appear straightforward, but the difference between a quick DIY setup and a professional-grade installation can significantly impact performance, reliability, and long-term pedal life. The ATAC XC 2 [paid link], designed for gravel and cross-country riders, is renowned for its self-cleaning design, robust composite body, and easy engagement system. However, proper installation is essential to prevent creaking, premature wear, or poor cleat alignment. This guide covers everything you need to know about setting up your ATAC XC 2 pedals, when it makes sense to do it yourself, and when to trust a mechanic.
Tools Required
- 8 mm hex wrench (for pedal installation)
- Torque wrench [paid link] (for precise tightening)
- Pedal grease (anti-seize compound recommended)
- Clean rag or shop towel
- Cleat mounting bolts and a 4 mm hex key
Understanding the TIME ATAC XC 2 Pedal System
The TIME ATAC XC 2 uses a spring steel engagement arch with a dual-rail retention mechanism. This design provides consistent entry and release, even in muddy or sandy conditions. The self-cleaning mechanism ensures mud and debris don’t interfere with engagement—a signature feature of TIME’s ATAC line.
The pedals are compatible with TIME ATAC cleats [paid link], available in two float options:
- 13° / 17° depending on cleat orientation
- 10° for the optional “Easy” cleat set
Because the float and release tension are mechanically fixed, proper cleat positioning on the shoe is critical for rider comfort and joint alignment.
DIY Installation: Step-by-Step Guide
Installing the TIME ATAC XC 2 pedals yourself is entirely possible if you have basic mechanical skills and the right tools. Follow these steps carefully for optimal results.
Preparing the Crank Arms
Before threading in the pedals, clean the crank arm threads with a rag. Apply a thin, even layer of anti-seize compound or pedal grease. This prevents galvanic corrosion and makes future removal easier.
Identifying Left and Right Pedals
Each pedal spindle is marked with an “L” (left) or “R” (right). The left pedal has a reverse (left-hand) thread, meaning it tightens counterclockwise. The right pedal uses a standard (right-hand) thread, tightening clockwise.
Installing the Pedals
- Insert the 8 mm hex key into the back of the pedal spindle.
- Begin threading each pedal by hand to avoid cross-threading.
- Once snug, use the torque wrench [paid link] to tighten each pedal to 35–40 Nm.
Avoid overtightening; excessive torque can damage the crank threads.
Mounting the Cleats
The ATAC XC 2 includes two cleats and mounting hardware. Position the cleats under the shoe ball, aligning them symmetrically. Use a 4 mm hex key to secure the bolts evenly. Adjust cleat rotation slightly to match your natural foot angle, then tighten each bolt to 5 Nm.
After mounting, test clip-in and release action several times to confirm smooth operation.
When DIY Installation Goes Wrong
A common DIY error is cross-threading the pedal spindle, which can permanently damage the crank arm. Another frequent issue is insufficient lubrication, leading to creaking noises or seized threads. Incorrect cleat placement can also cause knee discomfort or inconsistent release.
If you notice one side of the pedal not engaging smoothly, inspect for debris or check that the cleats are not worn unevenly. These are usually easy fixes, but incorrect diagnosis can mask deeper issues like bearing play or bent pedal axles.
Professional Installation: What Mechanics Do Differently
A professional bike mechanic will go beyond simple installation. They will check:
- Thread integrity and crank condition before installation.
- Torque accuracy using calibrated tools.
- Cleat alignment relative to your shoe’s natural stance and pedal stroke.
- Bearing play and lubrication inside the pedal body.
Professionals also inspect the pedal spindle seals and verify engagement smoothness under load. For new riders or anyone using clipless pedals for the first time, this expert setup ensures optimal comfort and safety.
A trained technician can also balance float and release angles across both sides of the pedal—something difficult to fine-tune manually.
Comparing DIY and Professional Installation
| Aspect | DIY Installation | Professional Installation |
|---|---|---|
| Cost | Free (assuming tools are available) | Typically $25–$50 |
| Precision | Depends on user skill | High, verified by torque and alignment tools |
| Cleat Fit | User-calibrated | Biomechanically aligned |
| Risk of Cross-Threading | Moderate | Very low |
| Bearing and Seal Check | Usually skipped | Always included |
| Best For | Experienced riders with mechanical confidence | Riders seeking precision, longevity, or first-time setup |
In most cases, confident home mechanics can safely install the TIME ATAC XC 2. However, professional fitting ensures peak efficiency and long-term pedal performance.
Maintenance Tips After Installation
Regardless of who installs the pedals, ongoing maintenance keeps the ATAC XC 2 working smoothly. Every few rides, check for:
- Pedal spindle tightness
- Cleat wear and bolt torque
- Bearing play or noise under load
Every 1,000 km, remove the pedals, clean the threads, reapply grease, and reinstall to maintain smooth operation.
Avoid using high-pressure water directly on the pedal body—TIME’s composite construction is durable, but the internal seals can be compromised under forceful washing.
Choosing the Right Option
If you frequently service your own bike and understand proper torque application, DIY installation is entirely appropriate for the TIME ATAC XC 2. However, if you’re new to clipless systems, ride competitively, or want perfect cleat ergonomics, professional installation is the superior choice.
Ultimately, the best installation is one that ensures correct alignment, smooth engagement, and consistent performance under real-world conditions. Whether installed in your garage or by a trusted mechanic, the ATAC XC 2 rewards precision with reliability.
