Be the first to review this product

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 thecrank 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.

The Campagnolo SRM PowerMeter uses 8 strain gauges providing industry leading accuracy of ±1.0%.
