The TIME MX 6 [paid link] pedals are known for their lightweight construction, efficient engagement system, and reliable performance across varied conditions. However, some riders eventually notice their pedals feeling loose or unstable after a few months of use. This looseness can stem from wear in the bearings, spindle play, or improper installation. Addressing these issues early helps preserve performance and extends pedal lifespan.
This guide explains the mechanical reasons behind loose-feeling MX 6 [paid link] pedals and outlines precise steps to inspect, tighten, and optimize them for long-term durability.
Understanding the TIME MX 6 Pedal Design
The MX 6 uses TIME’s ATAC (Auto Tension Adjustment Concept) mechanism, which provides easy engagement and self-cleaning capabilities. Its composite body is lightweight yet durable, and the steel axle runs on a combination of needle and cartridge bearings for smooth rotation.
A loose feel typically indicates one of the following issues:
- Axle or bearing wear causing lateral play.
- Improper installation torque on the crank arm.
- Bearing race or internal bushing deterioration.
- Overly dry internal components after prolonged use.
Recognizing these causes is essential before attempting any corrective steps.
Tools Required
- 8 mm hex key
- 6 mm hex key
- Torque wrench [paid link]
- Grease (water-resistant type)
- 13 mm cone wrench [paid link] (if servicing bearings)
- Replacement bearing and seal kit (optional for worn pedals)
Inspecting for Pedal Play
Begin by checking for lateral movement between the pedal body and axle. Hold the pedal and wiggle it side to side. Any noticeable play indicates internal wear or loosened components.
Next, rotate the pedals by hand. A gritty or rough feeling signals bearing contamination or lack of lubrication. Smooth rotation without excessive movement confirms that the bearings and spindle are in proper condition.
Finally, check crank arm torque. A loose pedal installation can mimic internal looseness. Tighten to the manufacturer’s recommended torque specification—35–40 Nm—using an 8 mm hex key.
Servicing the Pedal Bearings
When internal play persists, the issue usually lies in worn or dry bearings. Servicing involves removing the spindle, cleaning the components, and reapplying fresh grease.
- Remove the pedal from the crank arm. Use an 8 mm hex key to loosen it (counterclockwise on the drive side, clockwise on the non-drive side).
- Access the spindle assembly. Insert a 6 mm hex key into the axle end to hold it steady while loosening the end cap with a cone wrench [paid link].
- Disassemble carefully. Note the order of washers, seals, and bearings for correct reassembly.
- Clean thoroughly. Use a degreaser to remove old grease and contaminants.
- Inspect bearings and bushings. Replace any pitted, seized, or excessively worn components.
- Repack with fresh grease. Apply a moderate amount of waterproof grease to all moving parts.
- Reassemble and torque the end cap. Avoid overtightening, which can cause binding.
Once reassembled, the pedal should rotate smoothly with no lateral play.
Tightening the Spindle Assembly
Some TIME MX 6 pedals develop slight end-cap loosening over time, which introduces play even when bearings are intact. To correct this, tighten the spindle end cap until resistance is felt, then back it off one-quarter turn. This ensures correct preload without creating friction.
If the cap cannot hold its position, apply a small drop of medium-strength threadlocker before tightening. This prevents vibration-induced loosening during rides.
Preventing Future Looseness
Proper maintenance prevents premature wear and extends service intervals. Follow these practices regularly:
- Clean the pedals after wet rides to remove grit that accelerates bearing wear.
- Re-grease the spindle every 2,000–3,000 km depending on conditions.
- Check installation torque monthly to ensure the pedals remain secure.
- Avoid pressure washing directly at the pedal interface to prevent seal damage.
- Replace bearing kits annually if riding frequently in muddy or rainy environments.
Consistent maintenance keeps the MX 6 engagement mechanism crisp and stable, reducing the chance of side play or rotational resistance.
Optimizing Pedal Performance
To enhance responsiveness, many riders lightly grease the cleat contact points and adjust cleat tension using the TIME ATAC mechanism. The MX 6 offers natural float, which minimizes knee strain, but if the pedal feels imprecise even after tightening, check cleat wear.
Worn cleats often create a vague or loose sensation during engagement, which is easily mistaken for pedal body looseness. Replacing cleats restores precise engagement and eliminates play at the shoe interface.
Comparison: MX 6 vs. MX 12 Pedals
While both share the ATAC retention design, the MX 12 uses a carbon body and hollow steel axle, offering better stiffness and longer bearing life. However, the MX 6 provides better impact resistance for trail riders. If looseness is a recurring issue, upgrading to the MX 12’s enhanced spindle system offers improved durability with minimal weight gain.
Final Checks After Service
After reinstalling the pedals:
- Rotate the cranks to ensure smooth, resistance-free motion.
- Test ride to confirm that any prior looseness has been eliminated.
- Listen for clicking or knocking noises, which can indicate improper reassembly or insufficient grease.
If looseness persists despite servicing, the internal bearing seat may be worn beyond repair. In that case, a full pedal body replacement is recommended.
Conclusion
A loose feel in TIME MX 6 pedals typically arises from spindle play, worn bearings, or installation errors. With proper inspection, lubrication, and torque adjustment, most issues can be resolved quickly and effectively. Regular servicing prevents future wear and keeps the pedals functioning with the precise engagement and reliability that TIME components are known for.
