The SRM Origin PowerMeter, named for having all components designed by SRM - the original PowerMeter, is a modular-concept PowerMeter offering limitless compatibility with exchangeable spindles designed to accommodate a variety of frames including road, mountain, and track.
SRM offers the Origin in several versions and the modular foundation brings a "build your own" experience to customers. Start with a crank arm, 120 grams of the highest calibre carbon with LOOK's Trilobe Technology allowing one crank arm to function in three lengths; 170mm, 172.5mm, 175mm. Then choose your chainrings for 104BCD.
SRM Spider PowerMeters are the Origin of mobile power measurement. Since 1986 we have continuously refined our PowerMeters to meet ever-higher standards in technology, accuracy and reliability. For that reason, our PowerMeters are widely seen as the Gold-Standard for training with power.
Our 9th generation Spider PowerMeter takes our proven formula and updates it with modern features. The result is a PowerMeter that is easier to use, even more accurate, longer-lasting, and has improved connectivity.
Thanks to a combination of angle and torque measurement, the PM9 is now able to measure with higher accuracy in very low cadence situations and oval chain-rings do no longer have an impact on the recorded data. The integrated temperature sensor allows for maximum accuracy in changing conditions. Users are now able to show L&R balance, as well as combined Pedal smoothness.
PowerMeter 9 comes with many usability improvements. First is the Magnet-less cadence mode, which allows you to use the PowerMeter without any cadence magnet.
PowerMeter 9 can be used with ANT+ and Bluetooth LE. It connects to pretty much any head unit and comes with a mobile App. The App gives you access to live torque data, battery status information, firmware updates, and much more.
Co-developed with a leading producer of carbon components. The carbon crank arm offers superior stiffness to weight ratio. The LOOK Trilobe pedal insert allows for adjustable crank length; 170, 172.5, and 175mm.
Currently offered with 30mm spindle(149mm and 155mm) for ability to space your SRM Origin MTB to both Standard and Boost chainlines accordingly.
Focus on training - not battery life - with a rechargeable PowerMeter battery. Up to 100 hours of riding per charge.
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.
