The SRM Origin PowerMeter, named for having all components designed by SRM - the original PowerMeter, is our first modular-concept PowerMeter offering limitless compatibility. Interchangeable spindles, adjustable crank arm length, flexible chainring combinations, rechargeable battery option... all crafted around cutting-edge carbon crank arms offering superior stiffness to weight ratio for unparalleled performance!
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; Shimano 9100, Shimano 9000, or 110/110BCD chainrings from BOR or Miche, for example. The Origin PowerMeter lid, with a rechargeable port option, is interchangeable to match your chainring model. Then select your spindle type and length, BB30 and 24mm options.
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, even 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.
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.
The 110/110 asymmetrical BCD allows a variety of chainring size options from 50/34 to 55/42 as well as single ring setup. Select Shimano, SRM, BOR or other compatible designs. (Right: SRM rings)
Origin Aluminium is available with a crank lenth from 160-175 mm.
Origin Look Carbon comes with adjustable crank arms.
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 175 mm.
Origin THM Carbon are the lightest and stiffest cranks. The Carbon qualiti "Made in Germany" by THM is simply unrivaled. Available in 165-175 mm.
SRM produces the spindle in BB30 and 24mm so one PowerMeter can fit many frames. Road, mountain, track, cross and more can all be powered by one SRM now!
