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.
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.

The new Type 5 is a redesign of the classic JOF Fifty-Five. Designed for the serious rider that has committed to a forward geometry bike. Designed to be ridden out on the nose of the saddle, the rider just perching on the front to open his thigh angle and build big power. The Type 5 will purposely feel a little hard when you first ride it, give it a few rides and it will disappear under you. It has industry leading 105mm long seat rails to give a broad range of adjustment, the nose is 55mm wide so there is no need to use “zip ties” or other adaptions to find the all day comfort on this saddle. If you like to ride an aggressive bar drop to cheat the wind, the short nose design is the best, the narrow nose section that gradually tapers to the rear will keep your upper thighs from getting chaffed. Designed for both Men and Women, there are so many subtle features that add to the great experience when using this saddle. We included our rear Hydration mounts to easily add my bottle to your bike, the unique curved back shape will also cradle you for better hill climbs. This is a hugely popular saddle for IM racing or for short Sprints, it opens up your upper body so you can breathe better and have the best races of your life.
