Mountain bike racing has reached a new level of training technology with bikes now being equipped with power measurement devices. Once a course has been completed, the entire segment can be analyzed for power, cadence, heart rate and speed. This data collection has been shown to improve a rider’s training in preparation for specific events, as well as impacting decisions for tire-tread selection, tire air pressure and suspension set up!
The Shimano XTR, XT and SLX cranks are with the most used cranks out there. With the SRM Shimano MTB PowerMeter, we have one solution for all Shimano MTB cranks. Proven in MTB Marathon World Championships, it will face any terrain and condition without any problem.
The SRM Shimano MTB PowerMeter can be fitted to the whole line-up of Shimano MTB cranks: XTR, XT and SLX
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.
