The TIME ATAC XC 12 [paid link] pedals are among the most advanced cross-country and gravel clipless pedals available today, known for their lightweight carbon body, titanium axle, and self-cleaning engagement mechanism. However, even high-end pedals can start to feel loose over time if installation, tension adjustment, or bearing maintenance is overlooked. This guide explains the exact reasons your TIME ATAC XC 12 [paid link] pedals might feel loose and provides detailed steps to restore their solid, responsive feel.
Understanding the ATAC XC 12 Pedal Design
The ATAC XC 12 uses TIME’s signature Auto Tension Adjustment Concept (ATAC) system, which allows easy entry and reliable release even in muddy conditions. The carbon body houses a titanium axle, making the pedal both light and durable. The engagement system relies on a spring-steel arch that retains the cleat securely.
A pedal that feels loose is usually caused by one of three things:
- Cleat wear or incorrect orientation.
- Bearing play developing over time.
- Excessive float or tension setting not matched to rider preference.
Common Causes of Looseness in the ATAC XC 12
Worn or Incorrectly Mounted Cleats
TIME ATAC cleats [paid link] wear gradually, and as the interface between the cleat and the retention arch degrades, lateral movement increases. If the cleats are installed backward or not fully seated, engagement will feel sloppy even if the spring tension is correct.
Regularly inspect the cleat surface for uneven wear or rounding of the edges. Replace them when engagement begins to feel inconsistent. TIME recommends checking cleats every 3,000–5,000 km for optimal performance.
Axle or Bearing Play
The titanium spindle runs through two internal bearings—one needle bearing and one cartridge bearing. Over time, the factory grease can dry out, leading to play between the axle and the pedal body. A small amount of side-to-side movement is normal in used pedals, but visible rocking or audible clicking means service is required.
Loose End Cap or Improper Preload
The end cap at the outside of the pedal secures the bearing preload. If this loosens, the entire axle assembly gains play. A small turn of the end cap can usually remove the excess slack, but over-tightening can damage the bearing race.
Tools Required
- 8 mm hex wrench (for pedal removal and installation)
- 6 mm hex wrench (for end cap adjustment)
- Torque wrench [paid link]
- Lithium or waterproof bearing grease
- Replacement cleats (if necessary)
How to Fix Loose TIME ATAC XC 12 Pedals
1. Check Cleats and Shoes
Start by inspecting your cleats. If they are rounded or visibly worn, replace them immediately. Make sure to install new cleats with the arrow pointing forward and torque them to 5–6 Nm. The cleats must sit flush against the sole of the shoe with no spacers unless required for clearance.
2. Remove the Pedals
Use an 8 mm hex wrench to remove the pedals. Turn counterclockwise on the drive side and clockwise on the non-drive side. Clean the spindle threads with a degreaser before reinstallation to ensure a solid fit.
3. Inspect for Axle Play
Hold the pedal body and move it side-to-side relative to the spindle. If you feel noticeable movement, the bearing preload is likely loose.
To correct it, use a 6 mm hex key to gently tighten the end cap clockwise. Turn it in small increments (1/8 turn) until the play disappears. The pedal should rotate smoothly without resistance.
4. Service the Bearings (If Needed)
If tightening the end cap doesn’t solve the looseness, you may need to service the bearings. Remove the end cap and carefully slide out the axle. Clean all components thoroughly and apply a fresh layer of waterproof grease before reassembling.
Reinsert the axle, reinstall the end cap, and adjust until rotation is smooth but without play.
5. Reinstall Pedals and Test
Apply a small amount of grease to the pedal threads before reinstalling. Torque each pedal to 35–40 Nm. Once mounted, clip in and out several times to test engagement. Properly adjusted pedals will feel tight, precise, and consistent in float resistance.
Optimizing Pedal Feel and Engagement
The TIME ATAC XC 12 system offers two float options—13° and 17°, depending on cleat orientation. Riders seeking a tighter, more race-oriented feel can rotate the cleats 180° to use the smaller float angle.
Also, TIME’s tension spring automatically adjusts to release force, but if the engagement feels too soft, verify that both sides of the pedal have equal spring pressure. Uneven tension is often caused by dirt or dried mud inside the mechanism. Clean thoroughly with a mild degreaser and re-lubricate the springs using a light silicone spray.
Preventive Maintenance Tips
- Clean the pedals after every ride—especially after muddy or sandy conditions. The ATAC system is self-cleaning, but grit buildup can accelerate wear.
- Re-grease the bearings every 2,000–3,000 km. This maintains a consistent pedal feel and prevents spindle corrosion.
- Inspect end caps and cleats monthly. Loose end caps or cracked cleats are the earliest signs of wear.
- Avoid pressure washing. High-pressure water can force contaminants into the bearings, leading to premature wear.
Comparing the ATAC XC 12 to the ATAC XC 8
While the ATAC XC 8 [paid link] shares the same engagement mechanism, it uses a steel axle instead of titanium and a composite body rather than carbon. As a result, it is slightly heavier but generally develops less play over time due to the more robust materials. However, the XC 12 offers superior weight savings and a more efficient power transfer once properly maintained.
Final Thoughts
A loose-feeling TIME ATAC XC 12 pedal does not mean the pedal is worn out. In most cases, the issue can be resolved by tightening the end cap, servicing the bearings, or replacing worn cleats. When installed and maintained correctly, these pedals deliver exceptional performance, combining lightweight efficiency with reliable mud-clearing engagement. Regular inspection and lubrication will keep your ATAC XC 12 pedals performing like new for thousands of kilometers.
