SRAM RED 1 E1 Aero crankset
Couldn't load pickup availability
The SRAM RED 1 E1 Aero crankset is a carbon single-chainring crankset designed for riders seeking lightweight performance and aerodynamics. The crank arms are hollow and, thanks to a new process, are 29 g lighter than the previous generation. The aero-profile direct-mount chainring and X-SYNC technology help keep the chain in place.
Choose the crank arm length based on your height and riding position: it is available in 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.
