2x10 MTB SRM PowerMeter

Lightweight, Stiff and Durable

The Trinity Drilling Process creates an ultra-light CNC machined crank set

With many XC and endurance race courses remaining the same from year to year, having a power meter equipped bike allows the racer to record the specific demands needed to race a particular event. This allows the racer to tailor his or her training more specifically at critical time periods throughout the training season leading to goal events from which data was recorded in a previous season. Knowing how many accelerations, length, and duration of climbs, as well as average power for a certain event, can completely reshape the parameters of the typical training program. The SRM-Rotor 2x10 MTB PowerMeter was designed for the racer wanting to take his or her performance to new heights!

The SRM-Rotor 2x 10 PowerMeter is offered in the Rotor REX crankarm. The Rotor REX 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 REX model SRM PowerMeter allows for direct integration into BB30/PF30 as well as threaded BSA framesets. The SRM-Rotor 2x10 MTB PowerMeter allows for 950 hours of battery life and is available in a 120/80 BCD spider design.

Experience

Powered by experience

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.

Dependability

Dependability you can count on

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.

Race proven durability

Accuracy is everything

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.

Scientifically Proven

Race proven durability

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.
