Clavicula M³ is our modular, full-carbon crank for mountain bikes. An interchangeable carbon spider is key to its versatility — by changing the spider, you can fit double ring pairs (120/80 BCD or 104/64 BCD), classic triple rings (104/64 BCD), or XX1 single (76 BCD).
We also offer a 120/80 BCD spider for the SRM power meter, making Clavicula M³ the world’s lightest offroad SRM crankset at only 770 g, less than many other cranks without power measurement.
Weight of bare crankset is 340 g, and stiffness is second only to Clavicula SE. All common bottom-bracket types are supported including BSA, BB30, PF30, Shimano Pressfit (with adaptor), and BBright™.
Available also with the SRM PowerMeter. For orders and more info check the website SRM.
