SRM Powermeter Shimano 11-Speed Launched

With this in mind Shimano developed new Dura-Ace 9000 chain rings which are 20% stiffer than previous rings. This not only benefits the shift, but also in power transfer from the crank arm through the spider and into the drivetrain. If you ride Shimano DuraAce 9000 mechanical or Di2 electronic, you will benefit from increased power transmission!

Available models: SRM-Shimano 11-Speed: 110mm BCD (53/39), (50/34), (52/36)

Designed around the exacting standards of the Shimano 9000 crankset.

Train 600 hours a year over the next five years.

The SRM was designed to keep you focused on your training, not on your next battery replacement.

Built one at a time.

Backed by a Three-Year Warranty.

Each SRM PowerMeter and PowerControl head-unit is made one at a time, by hand. Our production facilities are located in Jülich, 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.

1900-3000 hours of battery life, give each SRM year after year of uninterrupted use. A three-year global warranty against defects backs up your investment. The industry’s leading accuracy and data transmission yield unrivaled power measurement performance.

SRM uses a 144 point calibration protocol against a known mass measured to the exact gram. With precise 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 PowerMeter as the bench mark for measuring power in physiological and human performance research studies. We don’t claim anything, our accuracy is proven.

PowerMeters are designed to take whatever you can throw at them. Each SRM is sealed against water, snow, mud, sand, and cleaning solvents. SRM PowerMeters are designed to work. We back that up with a three-year global warranty. If you can break it, we’ll fix it.
