Campagnolo 4 Bolt


With Campagnolo Record level performance, the amazingly smooth C.U.L.T._ Ceramic bearings, and lightning-fast shifting of the Campy chainrings, SRM has a truly seamless option for Campy fans using the EPS_ electronic or mechanical shifting component groups.

At first glance, the unidirectional carbon fiber crank arms look similar to the Campy Record crankset, but look closer to notice a complete removal of the carbon fiber spider arms normally attaching the chainrings to the crank arm. Using the same carbon layup process and exacting specifications, the SRM-Campagnolo PowerMeter matches any Campagnolo drivetrain. Available with dual BCD 145/112, accommodating both standard and compact chainrings.

On top of that, the PowerMeter offers the freedom to install either 11-speed or 12-speed compatible Campagnolo chainrings, giving you the freedom to choose what you want and upgrade whenever you want.

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