Campagnolo Chorus cranks are not compatible with our powermeters. Installation involves more than just placement of the unit. Crank arms need to be tested for a number of variables to determine if it meets our engineering requirements. Hence we do not install on crank arms not on the approved list.
We are working to expand our list of compatible products and will continue to update the compatibility list on our website as more options are made available. Please review our compatibility list.
