We found in repeated tests that slow-speed brake with high weight ratio leads to higher brake temperatures and damage to rims. The slow speed side brake causes temperature to rise, even during slight braking.  

Our bikes are equipped with high-speed brakes that reduce speed over very short duration. In the braking interval, the temperature dropped quickly.  High-speed break preserves the viability of bike rim and breaks.  

In road endurance test, we used a 10km downhill test track to repeated test rim brake temperature stability. We used the highest intensity slow speed rear wheel brake at a speed of 30km/h, so that rim side brake is always in a state of temperature rise.  After reaching the maximum temperature, the braking force of the brake can be maintained and does not appear to increase brake edge deformation.
