Crank Faster, Climb Lighter, Ride Smarter
The SRAM Red E1 1x DUB Crankset with 50T Aero chainring is engineered for serious cyclists and time trial specialists who demand the ultimate in aerodynamics, weight savings, and drivetrain simplicity. SRAM’s lightest and stiffest road crankset just got even lighter, thanks to a refined manufacturing process and a new hollow carbon crank arm design, dropping 29g from the previous generation.
Built with DUB technology for maximum durability and compatibility, and featuring X-SYNC™ 1x chainring tech for unmatched chain retention, the Red E1 crankset delivers race-ready performance for road, triathlon, and gravel riders looking to set personal bests with confidence.
