The TIME MX 8[paid link] pedals are known for their durable carbon body, excellent mud-shedding design, and precise ATAC engagement system. However, even high-end pedals can begin to feel loose or unstable after extended use. A loose feeling can compromise pedaling efficiency, affect power transfer, and even risk long-term damage to the pedal body or axle. This guide explains why your TIME MX 8[paid link] pedals might feel loose and provides detailed steps to diagnose and fix the issue for optimal performance.
Understanding the TIME MX 8 Pedal Construction
The MX 8 pedals use TIME’s ATAC (Auto Tension Adjustment Concept) system, which relies on self-cleaning engagement bars and a hollow steel axle supported by cartridge bearings and bushings. The pedal body is made from carbon composite material, which balances weight and stiffness. Over time, wear in the bearing assembly or engagement mechanism can lead to side-to-side play or uneven feel during pedaling.
The pedal’s internal structure includes:
- A sealed cartridge bearing near the crank end.
- A bushing at the outer edge of the axle.
- A lock nut or retaining cap that secures the axle assembly.
If any of these parts experience wear or loss of preload, the pedal may start to feel loose or unstable.
Common Reasons for Loose TIME MX 8 Pedals
Several mechanical and setup-related issues can cause a loose pedal feel. Identifying the root cause is the key to applying the correct fix.
1. Axle or Bearing Wear
The most common cause of a loose feel in MX 8 pedals is bearing or bushing wear. As these components degrade, the axle can move laterally inside the pedal body. This play becomes noticeable when rocking the pedal from side to side.
2. Loose Retaining Nut or Axle End Cap
Inside the pedal body, a lock nut secures the axle. Over time or due to improper servicing, this nut can loosen, leading to unwanted movement. A small amount of internal play can feel significant at the pedal surface.
3. Cleat Wear or Incorrect Tension Setting
Although the TIME ATAC system automatically adjusts tension, worn or damaged cleats can create the impression of a loose pedal. If your shoe moves excessively when clipped in, the issue might not be the pedal itself but the interface between cleat and engagement bars.
4. Pedal Thread or Crank Arm Fitment Issue
If the pedal isn’t properly torqued into the crank arm or if there’s contamination between threads, it can loosen over time. This can create a wobble or clicking sensation under load.
5. Axle Damage from Over-Torqueing or Impacts
Hard strikes against rocks or curbs can bend or slightly misalign the axle. Even a minor bend can cause the bearings to seat improperly, producing a loose, uneven rotation.
Tools Required
- 8 mm Allen key
- 10 mm socket or thin wrench (for end cap)
- Torque wrench[paid link]
- Waterproof grease
- TIME bearing and bushing service kit (if replacement is needed)
Diagnosing a Loose Pedal
To determine the source of looseness:
- Check for Axle Play: Hold the pedal body and wiggle it side-to-side. Any noticeable lateral movement likely indicates bearing or bushing wear.
- Spin the Pedal by Hand: If the pedal doesn’t spin smoothly or makes grinding noises, the bearings are likely compromised.
- Inspect Cleat Fit: Clip your shoe into the pedal and test for side movement. Excessive float or slipping indicates worn cleats.
- Check Crank Arm Fit: Ensure the pedal is properly torqued into the crank arm (tightened to approximately 35–40 Nm).
How to Fix Loose TIME MX 8 Pedals
If you’ve identified internal play or bearing wear, follow these steps to restore a precise, solid feel.
Step 1: Remove the Pedal Axle
Using an 8 mm Allen key, remove the pedal from the crank arm. Then, unscrew the end cap at the outer edge of the pedal using a 10 mm socket. Slide the axle out carefully, noting the order of the bearing and bushing.
Step 2: Inspect Bearings and Bushing
Examine both the inner cartridge bearing and the outer bushing. If you notice corrosion, flat spots, or looseness, they should be replaced. The MX 8 service kit includes both components for each pedal.
Step 3: Clean and Re-Grease
Before reassembly, clean the inside of the pedal body thoroughly with a degreaser. Apply a thin layer of high-quality waterproof grease to the new bearing and bushing. Grease the axle shaft lightly before inserting it back.
Step 4: Reassemble and Secure the Axle
Slide the axle into the pedal body and reinstall the retaining nut or end cap. Tighten it securely but avoid overtightening, as excessive preload can cause premature wear. Check for smooth rotation.
Step 5: Reinstall Pedal and Torque Properly
Reinstall the pedal onto the crank arm. Use a torque wrench[paid link] to ensure proper tension (35–40 Nm). Spin the pedal to confirm that it rotates smoothly without any side play.
Preventing Future Looseness
Regular maintenance is the best way to extend the lifespan of your TIME MX 8 pedals. Apply the following practices:
- Inspect bearings every 3–6 months, depending on riding conditions.
- Avoid power washing directly at the pedal, as it forces water into the bearing assembly.
- Re-grease the axle and bearings annually or after heavy rain riding.
- Check pedal torque periodically to ensure it remains properly tightened.
- Replace cleats when they show rounding or uneven engagement surfaces.
By following these maintenance steps, you can preserve the crisp, positive engagement that TIME pedals are known for.
Troubleshooting Persistent Looseness
If you’ve serviced the bearings and the pedal still feels loose, the issue may be internal wear in the carbon composite pedal body itself. Over thousands of engagement cycles, the internal bore can elongate slightly, reducing the fit between the axle and housing. In such cases, replacement of the pedal body is the only long-term solution, as the structural integrity cannot be restored through adjustment alone.
Additionally, always confirm that your crank arms are free from thread damage. Cross-threading or worn crank threads can cause repeated pedal loosening, even after proper torqueing.
Final Thoughts
A loose feeling in your TIME MX 8 pedals can undermine the precision and confidence you expect from a high-performance clipless system. Fortunately, with careful inspection and routine servicing, you can restore the pedal’s solid feel and maintain its renowned ATAC engagement quality. Regular bearing service, cleat inspection, and torque checks will keep your MX 8 pedals performing flawlessly for many seasons of riding.
