Our Alloy Short Cranks are a John Cobb engineered product designed to improve speed and comfort on the bike for all athletes. These hot forged alloy cranks have a GXP style axle (22/24mm) that are easy to install and work well with all road frame bottom bracket standards. They are available in compact, mid-compact and standard options and come in 4 different crank arm lengths 145mm, 155 mm, 160 mm or 165 mm.

IMPORTANT NOTE:

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:

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 540 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.
