Sram Red E1 Dub Crank Arms

As soon as Sram found a way to make our lightest and stiffest crank arms even lighter, it got to work. A new process allows us to shave more grams off our hollow carbon arms and, to keep up with current bike fit trends, we have added our first carbon crankset option in a 160 mm length.

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.
