SRAM Red AXS E1 Aero 50T crankset

SRAM Red AXS E1 Aero DUB 50 teeth 12 speed crankset black/silver

At SRAM , they don't rest on their laurels. When they found ways to make their lightest and stiffest crankset even lighter, they jumped at the opportunity. A new process further reduces the weight of their hollow carbon arms. To stay ahead of current trends, they have added their first carbon crank length option of 160mm. Paired with a 1x aero chainring, this SRAM Red AXS E1 Aero 50-tooth 12-speed crankset is ready to help you break your personal bests.
