Racing-Focused Rear Belt for Cero M Chassis

The 3Racing SAK-CM104A 225mm rear belt is specified for the Cero M chassis to provide predictable tooth engagement and repeatable power transfer under race conditions. It is intended as a performance-minded replacement part for drivers focused on setup consistency.

Optimised for Tuning and Setup

This belt supports fine tuning of tension and pulley alignment, enabling precise drivetrain adjustments that affect traction and throttle response. Use standard setup checks to validate tension and eliminate lateral slack.

Practical Race Prep Notes

Install the belt following the Cero M routing and measure belt tension against your preferred reference. Recheck after a short run-in sequence and look for uniform tooth contact across the pulley width to ensure reliable behaviour during competition.
