The TIME MX 8 [paid link] pedal is a lightweight, durable clipless pedal designed for riders who demand both performance and reliability on mixed terrain. Known for its ATAC (Auto Tension Adjustment Concept) system, the MX 8 [paid link] offers excellent mud-shedding capabilities and consistent engagement. However, achieving optimal performance depends heavily on compatibility—both with cleats and drivetrain components. Understanding what works, what doesn’t, and what to avoid ensures the pedal functions flawlessly and delivers the precise feel TIME is known for.
Understanding TIME MX 8 Pedal Design
The MX 8 is built around a composite body with a hollow steel axle, offering a balanced weight-to-strength ratio ideal for road, gravel, and cross-country applications. The ATAC system allows for easy engagement and self-cleaning, making it less prone to clogging compared to SPD-style systems.
The cleat interface is central to the pedal’s performance. TIME’s proprietary ATAC cleats [paid link] use a lateral and angular float system that minimizes knee strain and allows for a more natural pedaling motion. Unlike SPD pedals, which use a more rigid float, the MX 8’s engagement is dynamic, meaning the pedal automatically adjusts to rider input and terrain feedback.
Cleat Compatibility and Best Pairing Options
TIME MX 8 pedals are only compatible with TIME ATAC cleats [paid link]. This includes both the ATAC Easy cleats and the ATAC standard release cleats.
- ATAC Easy Cleats are designed for riders who prioritize quick entry and exit. They release with less force and a broader angle, making them ideal for beginners or gravel riders frequently unclipping in technical terrain.
- Standard ATAC Cleats, on the other hand, provide firmer retention with a more defined release point, better suited for performance-focused riders seeking a consistent engagement feel.
Both cleat types offer ±5° angular float and 6 mm lateral float, promoting joint comfort over long rides. However, it’s important to note that TIME’s road-specific Xpresso or Xpro cleats are not compatible with the MX 8 system. Attempting to use them can result in incomplete engagement, premature wear, or even pedal body damage.
Shoe Compatibility and Mounting Considerations
The TIME MX 8 pedal requires shoes with a 2-bolt SPD-style cleat mount. Most mountain, gravel, and adventure road shoes are compatible, while standard road shoes typically are not. The cleat platform fits into a slightly recessed sole cavity, providing walking comfort while keeping the engagement clean.
When choosing a shoe, ensure the sole design doesn’t interfere with the cleat wings or retention bars of the MX 8. Shoes with overly deep tread patterns can limit cleat movement and prevent full engagement. Using a spacer plate can resolve minor interference issues, but excessive clearance problems indicate an incompatible sole design.
The MX 8’s body shape also supports broad-soled shoes well, offering better lateral stability during high-torque efforts. However, minimalist XC shoes with narrow soles may feel less supported, especially under heavy pedaling loads.
Drivetrain and Crank Arm Compatibility
The TIME MX 8 uses a standard 9/16″ pedal thread, compatible with virtually all modern cranksets from Shimano, SRAM, FSA, and Rotor. Installation torque should be maintained at 35–40 Nm, using a 15 mm pedal wrench [paid link] or a hex key from the inside of the crank arm if the model allows.
Crank arm shape can influence pedal clearance. TIME MX 8 pedals have a moderate Q-factor, providing adequate heel clearance for most riders. However, on cranks with inward-bent arms, like certain carbon cranksets, the pedal may sit closer to the frame, slightly altering the stance width. Riders sensitive to stance changes may need to use pedal washers for optimal alignment.
Additionally, the MX 8 pedal’s tension spring and engagement mechanism perform best when paired with drivetrains that maintain smooth power delivery. Harsh chainline angles from misaligned front derailleurs or incorrect bottom bracket spacing can contribute to uneven pedal feel, even though the issue originates elsewhere in the drivetrain.
What Fails: Common Incompatibility Issues
Several compatibility mistakes can compromise MX 8 performance or longevity. The most common issues include:
- Using SPD or Look-style cleats: These cleats are dimensionally different and will not engage properly. Forcing them into the ATAC mechanism can permanently deform the engagement wings.
- Installing cleats on worn shoe soles: If the shoe sole is uneven or degraded, the cleat sits at an angle, causing inconsistent engagement and premature release.
- Mixing cleat types: Using one Easy cleat and one Standard cleat leads to unbalanced float and inconsistent tension. Always use a matched pair.
- Improper shoe-pedal interface spacing: Shoes with thick tread or insufficient recess depth can limit full cleat engagement.
- Lack of lubrication or contamination: Grit or corrosion on the pedal’s engagement bars can reduce the self-cleaning function and hinder cleat release.
Each of these issues can create the perception that the pedal is malfunctioning, but in reality, they stem from improper compatibility or maintenance practices.
What Works: Ideal Set-Up Combinations
The optimal TIME MX 8 setup involves the following compatibility parameters:
- Pedal System: TIME MX 8 with standard ATAC or Easy cleats.
- Shoes: 2-bolt SPD-style gravel or XC shoes with moderate tread depth (e.g., Shimano XC7, Giro Privateer, or Specialized Recon).
- Crankset: Any 9/16″ threaded arm with adequate clearance, such as Shimano GRX, SRAM Rival, or Rotor Aldhu.
- Rider Position: Cleat placement aligned to the ball of the foot, with neutral float angles to prevent knee stress.
This setup offers reliable engagement, predictable float, and balanced power transfer suitable for long rides and mixed-terrain conditions.
What to Avoid with the TIME MX 8
Avoid pairing the MX 8 with any of the following:
- 3-bolt road shoes: The cleat interface will not align with the pedal, risking severe engagement failure.
- Non-TIME cleats: Even minor dimensional variations disrupt the ATAC retention system.
- High-tread hiking shoes: Their sole lugs interfere with the cleat wings and may prevent proper clipping in.
- Aggressive cleaning agents or degreasers: They can strip the pedal’s internal seals and affect spring performance.
- Cross-brand replacement cleats: While some third-party options claim compatibility, their release profiles differ, compromising safety and engagement consistency.
Conclusion
The TIME MX 8 pedal delivers exceptional performance when paired with the correct components and cleats. Its ATAC system offers unmatched self-cleaning and smooth engagement, but these benefits rely entirely on maintaining strict compatibility standards. Using the proper TIME ATAC cleats, ensuring suitable shoe selection, and verifying crank clearance will keep your MX 8 pedals performing flawlessly. Avoid cross-brand cleat use and improper installation practices to preserve the pedal’s smooth operation, reliable float, and long-term durability.
