Need a shorter than average crankarm length for fit, injury, comfort, or efficiency reasons? JCOB always been your short crankset source, and our Alloy Crankset has been the industry go-to unit. The Carbon One Crankset shares the same JCOB engineering and design, yet it is both lighter at 690 gram and stiffer than its alloy counterpart.
The Carbon One Crankset now uses a Shimano style axle with pinch bolts. It is easy to install and always delivers smooth, efficient performance. It’s available in compact and mid compact chainring configurations.
All options are perfectly compatible with 10 or 11-speed drivetrains. We also offer BB Infinite bottom bracket options to ensure compatibility in any frame.
