NOS Sram Omnium crankset w/ GXP bottom bracket


Items that are in stock can be added to cart.

Maybe you know this, or maybe you're new to the game and don't, but the Omnium was the very first external bearing track crank in the world.

Designed for world-class professional track racing, but also at home on the street as the ultimate "fixie cred" crankset, the Omnium features strong, super stiff 7050-T6 arms and a 5mm thick 48t 7075-T6 aluminum chainring.

Includes an English-threaded Sram GXP bottom bracket, which you should never, ever, EVER use spacers on to fix clearance problems.
