The SRM Science PowerMeter was designed to be benchmark of 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 Science 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, the SRM Science is built to measure the most extreme forces, as well as the most subtle changes in a cyclist’s pedal stroke.
The SRM Science PowerMeter version is available for both the square-tapered and Octa-link bottom brackets. The SRM Science PowerMeter arms can be exchanged to fit either format. Available only in 130mm BCD (53/39).
With optional adjustable length crank arms from 150-190mm.
Precisely measure power to within 0.5% of error!
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.
SRM's are designed to take whatever you can throw at them. From freezing temperatures, to boiling heat, SRM's are designed to handle temperature compensation while maintaining accuracy with our "Auto" offset feature. Each SRM is designed to be sealed against water, snow, mud, sand, and cleaning solvents. SRM's are designed to work. Period.
