Rotor Track

The SRM Track PowerMeter was designed to be the pinnacle of precise power measurement in the sport of cycling. For over 27 years, the world’s most prestigious exercise physiology laboratories and training centers have relied on the SRM Science for measuring athletes’ performance. The SRM Rotor Track PowerMeter is a true scientific measuring device with absolute transparency for accurate recalibration and data replication. Reinforced to allow for sprinting forces up to 4000 watts and built to measure the most extreme forces, as well as the most subtle changes in a cyclist’s pedal stroke.

The SRM-Rotor Track PowerMeter is offered in the Rotor 3D crankarm with a 24mm steel bottom bracket axle. The Rotor 3D arms use the Trinity Drilling Process to create three holes drilled end to end, length-wise, through a solid piece of aluminum. This allows for an extremely low weight as well as an optimized weight to rigidity ratio. The Rotor 3D model SRM Track PowerMeter allows for direct integration into threaded BSA framesets. The SRM-Rotor Track PowerMeter allows for 1900 hours of battery life and is available in a 144 BCD spider design.
