The TIME MX 8 [paid link] pedals are known for their lightweight composite body, robust engagement system, and self-cleaning ATAC mechanism, making them a reliable option for riders who demand precision and efficiency. However, like any mechanical component, even well-engineered pedals can develop stiffness, noise, or resistance during rotation. This guide provides a complete breakdown of how to diagnose, repair, and maintain your TIME MX 8 [paid link] pedals for smooth, silent, and efficient performance.

Tools Required

  • 8mm hex key
  • Pedal wrench [paid link] (optional for removal)
  • Torque wrench [paid link] (capable of 35–40 Nm)
  • Small flathead screwdriver
  • Needle-nose pliers
  • Bearing puller or extractor tool
  • Grease (high-quality waterproof type)
  • Light lubricant or pedal-specific oil
  • Shop rag or microfiber cloth

Understanding the TIME MX 8 Pedal Design

The TIME MX 8 uses a carbon composite body with a steel axle and a sealed bearing system. Its ATAC (Auto Tension Adjustment Concept) engagement mechanism is designed to clear mud and debris automatically. Unlike some other clipless systems, the MX 8 has a self-centering feature that keeps cleat engagement predictable and consistent.

Knowing these design fundamentals helps identify where stiffness or noise originates. Most common issues come from the bearing assembly, axle seals, or cleat interface.

Common Causes of Noise or Stiffness

Stiffness or noise in TIME MX 8 pedals typically points to one of the following mechanical conditions:

  • Contaminated Bearings: Dirt, moisture, or old grease can cause friction and resistance inside the spindle.
  • Dry or Worn Bushings: When lubrication is depleted, metal-on-metal contact increases drag.
  • Loose Pedal Body: Excess axial play can create clicking or creaking under load.
  • Worn Cleats: Metal cleats with uneven wear affect entry/exit smoothness and engagement noise.
  • Improper Installation: Over-torqued or misaligned spindles can lead to rotational resistance.

Step-by-Step Diagnostic Process

1. Check Pedal Free Rotation

Spin each pedal by hand while the crankset is stationary. A smooth rotation indicates proper lubrication and bearing condition. If resistance or grinding is felt, proceed with bearing inspection.

2. Inspect for Lateral Play

Hold the pedal body and attempt to move it side to side along the axle. Any noticeable movement suggests worn bearings or a loosened end cap.

3. Listen for Creaks and Clicks

While riding, identify whether the noise occurs under load or during rotation. A creak during load transfer (especially uphill) often points to the pedal threads or crank interface, while rotational noise usually comes from the pedal internals.

4. Examine Cleat Interface

Remove and inspect cleats on your shoes. Rounded edges or uneven wear can cause metal-on-metal noise and difficult disengagement. Replace cleats if they are visibly worn or uneven.

Servicing and Fixing Stiff or Noisy Pedals

Disassembly and Cleaning

  1. Remove pedals using an 8mm hex key or pedal wrench [paid link].
  2. Unscrew the end cap using a flathead screwdriver.
  3. Slide the axle assembly out of the pedal body.
  4. Wipe the inside of the pedal body and axle clean with a cloth.
  5. Inspect the bearings and bushings for rust, dirt, or pitting.

Bearing Service or Replacement

  • If bearings feel rough when rotated by hand, remove them using a bearing puller.
  • Press in new sealed bearings of the same specification (consult TIME’s service manual for correct dimensions).
  • Apply a small amount of high-quality waterproof grease inside the housing before reinstalling the axle.

Reassembly and Lubrication

  1. Grease the pedal axle and bearing surfaces evenly.
  2. Slide the axle back into the pedal body.
  3. Tighten the end cap securely but do not overtighten—this can create unnecessary resistance.
  4. Reinstall pedals onto crank arms, torquing to 35–40 Nm.
  5. Apply a light lubricant to the ATAC mechanism to improve spring movement.

Optimizing Engagement Feel

After reassembly, check cleat tension and entry/exit smoothness. TIME MX 8 pedals rely on their ATAC spring mechanism for consistent tension, so no manual tension screw exists. However, engagement can feel either tight or loose depending on cleat wear.

To optimize feel:

  • Use newer cleats for a firm, predictable connection.
  • Clean the engagement mechanism after every few rides, especially in muddy or wet conditions.
  • Apply a drop of lubricant on the spring pivots and wipe away excess oil.

Preventing Future Noise and Stiffness

Regular maintenance can significantly extend the lifespan of your MX 8 pedals. Follow these preventative tips:

  • Clean weekly: Rinse with mild soap and water, avoiding high-pressure sprays that force water into bearings.
  • Re-lubricate monthly: Add a few drops of light oil to the engagement system and regrease the axle every 3–6 months.
  • Check torque regularly: Ensure pedals remain snug on the crank arms. Loose threads can creak under load.
  • Replace cleats every 3,000–5,000 km: Worn cleats are a major source of noise and poor engagement.

Troubleshooting Persistent Issues

If noise or stiffness persists after servicing, consider the following checks:

  • Crank Arm Interface: Clean and grease pedal threads before reinstalling. Dry interfaces often creak under torque.
  • Axle Bend or Damage: A bent axle can create off-center rotation and excessive resistance. Replace the axle if runout is visible.
  • Contaminated Seals: Replace rubber seals if they show cracking or distortion, as this can let debris enter the bearing chamber.

Comparison: TIME MX 8 vs. Shimano XT PD-M8100

While both models serve cross-country and trail riders, the TIME MX 8 offers a lighter composite construction and self-cleaning engagement, while the Shimano XT focuses on tension adjustability and steel durability. Riders who prefer minimal maintenance often favor the TIME MX 8 for its consistent feel, while those seeking adjustable entry resistance may choose the XT model.

Conclusion

Noisy or stiff TIME MX 8 pedals typically stem from bearing contamination, dry bushings, or worn cleats. With regular inspection, cleaning, and lubrication, these pedals can maintain a smooth, quiet rotation and consistent engagement for thousands of kilometers. Proper torque application, routine servicing, and timely bearing replacement will ensure your MX 8 pedals deliver the precise performance that TIME components are known for.
