Sram Crankset Red 1 E1 Aero Black

We’re not ones to rest on our laurels. So when we found ways to make our lightest and stiffest crank even lighter we went for it. A new process drops further grams from our hollow carbon arms and to stay on top of current fit trends we’ve added our first carbon 160mm crankarm length option. Paired with an aerodynamic 1x chainring this crank is ready to help you smash prs. - single-ring drivetrain simplifies functionality and reduces weight - direct mount aero chainrings for better aerodynamics - x-sync wide-tooth narrow-tooth chainring technology provides maximum chain control - ultra-light hollow carbon fiber crankarms are 29 g lighter than previous generation - dub bottom bracket adds durability and simplicity - can be upgraded to a power meter - available in 160 165 167.5 170 172.5 and 175 mm lengths
