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 160 mm or 165 mm.
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.
