The XPRO 10 pedals from TIME are known for their durability, lightweight design, and exceptional performance. However, like any high-performance component, they may occasionally develop issues such as noise or stiffness, which can negatively affect your ride quality. Diagnosing and fixing these problems promptly can help you restore smooth functionality and avoid further damage. This guide will walk you through the most common causes of noise and stiffness in XPRO 10 pedals and provide clear solutions for fixing them.

Identifying the Source of Noise or Stiffness

Before attempting to fix any issue, it’s important to identify whether the problem is caused by the pedals themselves or other related components like the crankset or bottom bracket. Common noises from XPRO 10 pedals typically include squeaking, clicking, or grinding sounds, while stiffness is usually characterized by difficulty in pedaling or feeling resistance during engagement and disengagement.

Common Causes of Noise in XPRO 10 Pedals

1. Pedal Bearings:
   Worn or dry bearings inside the pedal body are often the primary source of noise. As the bearings degrade, they can create friction, leading to annoying squeaks or grinding noises.
2. Cleat Position and Interface:
   If the cleats are misaligned or have worn-out retention mechanisms, they can cause clicking sounds when you pedal. Misalignment between the pedal and the cleat engagement points may also result in stiffness when you try to clip in or out.
3. Pedal Body Contact with Crank Arm:
   Pedal bodies that make contact with the crank arm due to improper installation can also create squeaky sounds. Ensure that the pedal is tightened correctly to avoid any movement that might cause friction.
4. Dirt and Debris:
   Small particles of dirt or gravel can get lodged in the pedal mechanism, causing friction and noise when pedaling. The build-up of dirt can also create resistance in the pedal, leading to stiffness.

Common Causes of Stiffness in XPRO 10 Pedals

1. Lubrication Issues:
   Insufficient or old lubrication in the pedal’s moving parts can cause increased friction, leading to stiffness during pedal rotation. This issue can occur if the pedals have not been serviced in a while.
2. Engagement Mechanism:
   If the pedal’s engagement mechanism becomes clogged or contaminated with dirt or debris, it can lead to difficulty when clipping in or out. This can also create a feeling of stiffness in the pedal’s movement.
3. Worn-out Springs:
   Over time, the tension springs within the pedal system may lose their elasticity, leading to a stiffer engagement and disengagement feel. This can make it harder to clip in and out of the pedals.

Steps to Diagnose and Fix Noisy or Stiff XPRO 10 Pedals

1. Inspect the Pedal Bearings

• Tools Required:
  • Pedal wrench[paid link]
  • Lubricant (specific to pedal bearings)
  • Rag for cleaning
  • Cleaning brush
• Procedure:
  1. Use a pedal wrench[paid link] to remove the XPRO 10 pedals from the crankset.
  2. Inspect the bearings by gently spinning the pedal axle. If you notice any roughness or hear grinding sounds, the bearings may need replacement or lubrication.
  3. Clean the pedal body thoroughly using a rag and cleaning brush to remove any dirt or grime. Apply a small amount of lubricant to the pedal bearings.
  4. Reinstall the pedals and check for improvement. If noise persists, consider replacing the bearings.

2. Check the Cleat and Pedal Interface

• Tools Required:
  • Allen wrenches[paid link]
  • Grease
• Procedure:
  1. Check the condition of the cleats and ensure they are properly positioned on your cycling shoes.
  2. If the cleats are worn or damaged, replace them with new ones. If the cleats are dirty, clean them with a damp cloth.
  3. Examine the pedal’s engagement mechanism for debris or dirt. Clean the mechanism thoroughly, ensuring the interface between the pedal and cleat is smooth.
  4. Apply a thin layer of grease to the cleat-to-pedal contact points for smoother engagement and disengagement.

3. Inspect Pedal Installation

• Tools Required:
  • Pedal wrench
  • Torque wrench[paid link] (optional)
• Procedure:
  1. Check the tightness of the pedal on the crank arm. Pedals that are improperly installed may create friction or noise during riding.
  2. Ensure the pedals are torqued to the manufacturer’s specifications, typically around 35–40 Nm. Over-tightening or under-tightening can cause unwanted friction or movement.

4. Clean the Pedals and Mechanism

• Tools Required:
  • Degreaser
  • Rag for wiping down
  • Compressed air (optional)
• Procedure:
  1. Clean the pedal bodies and mechanism thoroughly with a degreaser to remove dirt, debris, or old lubrication.
  2. Use compressed air or a brush to clean out hard-to-reach areas, such as around the engagement mechanism and spring.
  3. Apply fresh lubrication to the moving parts, especially to the pedal spindle and spring mechanism.
  4. Wipe away excess lubricant to prevent attracting more dirt.

5. Address Tension Spring Issues

• Tools Required:
  • Allen wrenches[paid link]
  • Lubricant
• Procedure:
  1. Check the tension springs within the pedal mechanism. If the pedal feels too stiff when clipping in or out, the tension spring may need adjustment or replacement.
  2. Adjust the tension using the provided mechanism, if applicable. If the spring has lost its elasticity, it may need to be replaced.
  3. Reinstall the pedals and test the engagement and disengagement to ensure smooth operation.

Conclusion

By following the above steps, you can effectively diagnose and fix any noise or stiffness issues with your XPRO 10 pedals. Regular maintenance, including bearing lubrication, cleat and pedal interface cleaning, and tension adjustments, will help you keep your pedals running smoothly for years. If the problems persist even after following these steps, it may be worth seeking professional help to inspect and replace the components that cannot be serviced on your own.
