The SRAM RED XPLR AXS Power Meter Crankset E1 is SRAM's top gravel crankset, with hollow carbon arms and a dual-sided power meter in the spider, for gravel racers and adventure riders who want light weight and precise power. It weighs 516 g in 172.5 mm with a 40T ring.
Power is accurate to +/-1.5% and auto-calibrates as you ride. A CR2032 coin cell gives about 200 hours, and the IPX7 rating handles dust, sweat and wash-downs. The DUB Wide spindle and 47.5 mm chainline suit frames with big tyre clearance, on 12 or 13-speed drivetrains. Bottom bracket not included.
