With Campagnolo Record® level performance, the amazingly smooth C.U.L.T.® Ceramic bearings, and lightning fast shifting of the Campy XPSS® chain rings, SRM now has a truly seamless option for Campy fans using the new EPS® electronic or mechanical shifting component groupos.
At first glance, the unidirectional carbon fiber crank arms look similar to the Campy Record crank set, but look closer to notice a complete removal of the carbon fiber spider arms normally attaching the chain rings to the crank arm. This new crank set is manufactured exclusively for SRM, by Campagnolo in their Vincenza factory. Using the same carbon layup process and exacting specifications, the new SRM-Campagnolo PowerMeter matches to any Campagnolo 11 speed drivetrain. Available with dual BCD 145/112, accommodating both standard and compact chainrings.
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.
The SRM Campagnolo PowerMeter can be fitted with Campagnolo 11s and 12s chainrings.
Hollow Carbon Arms for reduced weight, while maintaining stiffness to weight ratio with Campy’s Ultra-Hollow™ Technology.
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.
