The SRAM RED 1 E1 Aero crankset is a carbon single-chainring crankset designed for riders seeking a lightweight, aerodynamic setup. The crank arms are hollow and, thanks to a new process, are 29 g lighter than the previous generation. The direct-mount aero-profile chainring and X-SYNC technology help keep the chain in place.
Choose the crank arm length based on your height and riding position: this version is 160 mm, while the range includes 160, 165, 167.5, 170, 172.5 and 175 mm. The DUB bottom bracket adds durability and makes installation simple, and the crankset can be set up for a power meter.
