The SRAM Red E1 groupset is SRAM’s lightest electronic disc brake groupset ever. With revisions to the shifters and brakes, it may also be the most ergonomic, and quickest braking electronic groupset ever. This SRAM Red E1 Power Crankset improves upon the previous D1 crankset by reducing weight and increasing durability, and features SRAM’s Spider-based power meter for supremely accurate power readings.
