CARBON ONE GXP CRANKS

Need a shorter than average crankarm length for fit, injury, comfort, or efficiency reasons? Cobb has always been your short crankset source, and our Alloy Crankset has been the industry go-to unit. The Carbon One Crankset shares the same Cobb engineering and design, yet it is both lighter at 690 gram and stiffer than its alloy counterpart.

The Carbon One Crankset has a GXP style spindle. 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 drive trains. We also offer BB Infinite bottom bracket options to ensure compatibility in any frame.
