What is SRM

Welcome to the Ultimate Training Tool
The SRM Training System is intended to take your training and racing to the next level by incorporating power based training into your routine. Training with a PowerMeter can allow you to specifically target the actual demands of your goals, pace your effort on race day, organize your workout schedule and track fitness trends with consistent, accurate data. Now you can objectively find your limits and train to push beyond them!

Crank based powermeter
First Patented in 1987, the SRM PowerMeter gave the cycling world one of its greatest innovations for performance based training tools. Training by the metric of power allows for cyclists to have truly objective data based on their performance, rather than rely on heart rate, speed and perceived exertion. Power output is not directly influenced by environmental factors.

Seamless Integration into every drivetrain
Each SRM PowerMeter has been designed for simple installation and intuitive operation, while being compatible with 9, 10, or 11 speed drivetrains. Road, mountain, triathlon, BMX or Track disciplines; if there is a need to improve cycling performance, there is an SRM to fit your bike!

Strain gauge based torque measuring
The SRM PowerMeter functions with a simple, yet exhaustively refined design. Inside each SRM PowerMeter are four measuring bridges connecting the chain rings (drivetrain) to the crank arms (the rider). As force from the rider's leg is applied to the crank arm (Torque), the bridges measure the amount of force being applied. That force is multiplied by the speed of the pedal stroke (known as Angular Velocity). Torque X Angular Velocity = Power!

ANT+ Compatible
While the SRM was designed to be used as a complete system, each SRM PowerMeter can also be paired with 3rd party compatible ANT+ head units allowing for expandability to smartphone app technology.

Measurement data
  • Power/cadence - from 0 – 4200 watts - the SRM measures scientifically-proven accurate power data
  • Heart Rate - EKG accurate heart rate transmitting and recording
  • Altitude - track your current altitude and altitude gained on a ride to reach your climbing goals
  • Energy - measure the mechanical energy expenditure during your ride
  • Speed - real time, average, and maximum speed values in kilometers or mile per hour
