TIME MX 4 Pedal Tension Adjustment: How to Get It Just Right

The TIME MX 4 [paid link] pedals are a durable and versatile option favored by gravel, cyclocross, and mountain bike riders who value stability and easy engagement. These pedals use TIME’s proprietary ATAC (Auto Tension Adjustment Concept) system, which offers self-cleaning engagement and a natural feel underfoot. However, even with their automatic tension management, riders often want to fine-tune the release and engagement feel to match their riding style. This guide explains how to correctly adjust the tension on your TIME MX 4 [paid link] pedals, maintain them for longevity, and troubleshoot issues related to release force and engagement performance.

Tools Required

  • 8 mm hex wrench
  • Small flathead screwdriver (for cleaning the spring housing)
  • Torque wrench [paid link] (optional, for reinstallation)
  • Soft brush or compressed air
  • Light pedal grease

Understanding TIME MX 4 Pedal Tension Mechanism

Unlike most clipless pedals that use a manual spring-tension bolt, the TIME MX 4 pedals feature a composite spring bar integrated into the ATAC mechanism. This system automatically adjusts to provide consistent retention while allowing slight variation in feel depending on the rider’s cleat positioning and wear.

The MX 4’s release tension isn’t directly adjustable via a screw or knob. Instead, riders fine-tune the release feel by using different cleat orientations or ensuring proper lubrication and maintenance of the spring mechanism. This unique design makes setup easier but requires attention to cleat orientation and cleanliness for optimal function.

Cleat Orientation and Its Effect on Tension

TIME ATAC cleats [paid link], supplied with the MX 4 pedals, offer two release angle options: 13° and 17°. The release angle determines how far you must twist your heel before disengagement. Riders looking for quicker exits or a looser feel should opt for the 13° orientation, while those who prefer a firmer hold should use the 17° setting.

To switch between these modes:

  1. Remove your cleats using a 4 mm hex wrench.
  2. Rotate each cleat 180 degrees and reinstall them.
  3. Ensure both cleats are installed symmetrically for even release force on both sides.

This simple adjustment can dramatically change the pedal’s engagement tension and improve comfort for riders who clip in and out frequently.

Step-by-Step Tension Optimization

1. Clean and Inspect the Pedal Body

Dirt and grit often build up around the ATAC mechanism, reducing float and creating a stiffer feel. Use a soft brush or compressed air to remove debris from the retention bar and spring area. For heavily contaminated pedals, use mild soapy water and dry them completely before proceeding.

2. Lubricate the Engagement Springs

Apply a thin layer of light grease to the steel engagement bars. Avoid over-lubrication, as it can attract dirt. TIME’s design relies on free movement of the spring arm, so clean lubrication ensures smoother float and easier entry and release.

3. Check Cleat Condition

Worn cleats can alter the release tension significantly. Inspect for rounding on the engagement tabs. Replace cleats if they appear worn or if release feels inconsistent. TIME recommends replacing ATAC cleats [paid link] approximately every 5,000–8,000 km, depending on riding conditions.

4. Verify Float and Engagement Feel

After cleaning and re-lubing, clip in and out of the pedals several times while stationary. You should feel smooth float (approximately 5 mm lateral movement) and predictable release. If the pedal feels tight, confirm that the cleat bolts are not overtightened or misaligned.

5. Adjust by Cleat Orientation

If engagement still feels too light or heavy, switch cleat orientation as described earlier. This provides the only mechanical method to alter release tension on the MX 4 system.

Common Tension Issues and Their Causes

Pedal Feels Too Tight

  • Cleats are installed in the 17° orientation.
  • Excess dirt or dried mud in the spring mechanism.
  • Cleats are worn or incorrectly aligned.
  • Pedal body lacks lubrication.

Pedal Feels Too Loose

  • Cleats are installed in the 13° orientation.
  • Cleat bolts are slightly loose or misaligned.
  • Excess grease inside the mechanism reducing spring friction.

Uneven Tension Between Left and Right Pedal

This issue often arises from uneven cleat wear or improper alignment. Clean and inspect both pedals, verify symmetrical cleat installation, and confirm equal torque on both cleat bolts.

Maintenance Tips for Consistent Tension

Routine maintenance is essential for preserving the MX 4’s release consistency. Every few rides, especially in wet or muddy conditions:

  • Remove the pedals and clean the retention bars.
  • Reapply a minimal amount of grease.
  • Check cleat tightness and reapply threadlocker if necessary.
  • Inspect the composite pedal body for cracks or wear near the spring interface.

TIME pedals are designed to be self-cleaning, but accumulated debris over time can still affect the spring’s movement. Maintaining a clean interface between the cleat and pedal ensures smooth engagement and consistent tension feel.

Performance Optimization Tips

  • Use the right shoes: Pair your MX 4 pedals with stiff-soled SPD-compatible shoes for efficient power transfer and better release feel.
  • Monitor cleat wear patterns: Uneven wear can make one side of the pedal feel tighter than the other.
  • Re-grease pivot areas periodically: Prevent squeaks and stiffness by applying a small amount of lubricant at the pedal spindle joint.
  • Test engagement in real conditions: Stationary testing can feel different from real-world use. Always fine-tune after a few rides.

Comparing TIME MX 4 Tension Feel to Similar Models

Compared to models like the TIME MX 6 [paid link] or MX 8 [paid link], the MX 4 offers a slightly firmer release feel due to its composite body and steel axle construction. While higher-end models use carbon and titanium components that provide a smoother float, the MX 4’s design favors durability and consistent spring response over lightweight optimization. Riders seeking a more customizable release tension may prefer the MX 6 [paid link], which offers a marginally different engagement arc due to its upgraded materials.

Troubleshooting Persistent Engagement Problems

If your pedals still feel inconsistent after cleaning and cleat adjustment:

  • Remove the pedal and inspect for spring deformation or excessive play at the retention bar.
  • Replace the spring unit if the pedal no longer holds the cleat securely.
  • Verify that both cleats are genuine TIME ATAC cleats, as third-party replacements can alter release force.

Final Check and Safety Reminder

After completing all adjustments, ensure that both pedals engage and release smoothly. Conduct a short test ride, clipping in and out multiple times on both sides. Proper tension adjustment should provide a firm yet controlled release, offering confidence on technical terrain and quick dismounts when needed.

By keeping your TIME MX 4 pedals clean, lubricated, and correctly oriented, you can achieve reliable performance and optimal tension without the need for complex adjustments or tools.
