SRAM GX Eagle FAT5 DUB Crankset

The SRAM GX Eagle FAT5 DUB crankset is a single-chainring 12-speed crankset designed for fat bikes, for frequent riders who want a robust, precise drivetrain. The cranks are made of forged aluminium, and the 30-tooth chainring uses the X-SYNC 2 profile, designed to retain the chain and deliver smooth shifting. The DUB interface provides consistent fitting, improved sealing and compatibility with multiple bottom brackets.

It is available in black only, so the choice comes down to crank length, available in 165, 170 and 175 mm. Before buying, check your current crankset length and bottom bracket type. It is compatible with DUB, BSA73, PF89.5, PF92, PF30 MTB73, BB30 MTB73 and BSA MTB68SP.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
