Clavicula M³ Road is our modular, full-carbon crank for road bikes. An interchangeable carbon spider is key to its versatility — by changing the spider, you can fit standard (130 BCD) or compact (110 BCD) ring pairs.
We also offer a spider for the SRM power meter, making Clavicula M³ the world’s lightest SRM crankset at only 740 g, less than many other cranks without power measurement. Weight with 110 BCD spider is 368 g, and stiffness is second only to Clavicula SE.
All common bottom-bracket types are supported including BSA, BB30, PF30, BB386 Evo, Shimano Pressfit (with adaptor), BBright™, and ITA.
Available also the version with the SRM PowerMeter. For orders and more info check SRM.
