Measuring the shock of off-road ( hard terrain) cycling

Buying a new mountain bike? You need to decide between bikes with front suspension only (a “hardtail”) or full (front and rear) suspension.

We decided to investigate the change in frame loading under different settings of the bike’s damper during drop testing. This would help infer the bike’s behavior as it goes up and down hills or over bumps. We used Mantracourt Fast USB Strain Module and connected it to a custom load pin provided by Aero Sense Technologies. The pin was positioned in place of the bolt at the front end of the shock absorber. The fine detail of the dynamic loads was guaranteed by the high speed measurement of the FSU at 4800 sps and the unprecedented stability across temperature ranges of the Micro-Measurements Advanced Sensors Technology strain gauges with modulus compensation.
