SRAM RED 1 E1 Aero crankset

The SRAM RED 1 E1 Aero crankset is a carbon single-chainring crankset designed for riders seeking low weight and aerodynamics. The crank arms are hollow and, thanks to a new process, are 29 g lighter than the previous generation. The direct-mount chainring with an aero profile and X-SYNC technology help keep the chain in place.

Choose the crank arm length according to your height and riding position: it is available in 160, 165, 167,5, 170, 172,5 and 175 mm. The DUB bottom bracket adds strength and ease of installation, and the crankset can be prepared for a power meter.

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.
