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.
Trek BB90 frames require the use of a BB Infinite BB90 bottom bracket with Cobb Cranks. Any use of another bottom bracket in a Trek BB90 frame with Cobb Cranks will void the warranty. Link to bottom bracket below:
