$165 + tax. Upgraded to a power meter crank and put chainrings on that. Now selling the crank arm set with bearings, bolt and bearing retention spring. The H11 model is designed for use with a road bike that has a thru-axle rear hub because those place the cassette a little farther to the right than on a bike with a regular QR skewer. This crank puts the chainrings a little farther to the right as well. I believe it is only a difference of 1 mm though. That is how picky Campagnolo is with their engineering. It is meant to be used whether the remaining parts are Chorus, Record or Super Record. Carbon fiber. Arms are 175 mm in length.
