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.
Uses the Trinity Drilling Process to create a sublimely stiff and industrial looking crankset!
SRM Science Level Accuracy to 99.5%!
Each SRM PowerMeter and PowerControl head-unit are made one at a time, by hand. Our production facilities are located in Julich, Germany and Colorado Springs USA. Every step of production is carried out by highly trained engineers and technicians who have a passion for quality craftsmanship.
A three-year global-warranty protects against defects and backs up your investments. Add on the industry's leading accuracy and data reception rate for a truly unrivaled power measurement device.
SRM uses a 144 point calibration protocol against a known mass measured to the exact gram. With exacting calibration and our auto-offset feature, the resulting power measurement of the SRM has error of less than 1%. The scientific community has been publishing peer reviewed research for over 20 years using the SRM PowerMeter as the bench mark for measuring power in physiological and human performance research studies. We don't claim anything, our accuracy is proven.
