What is the SRAM RED 1x XPLR AXS Power Meter Wide Crankset E1?

The SRAM RED 1x XPLR AXS Power Meter Wide Crankset E1 is SRAM's flagship gravel crankset with integrated power measurement. A spider-based power meter delivers dual-sided power data accurate to within +/-1.5%, unaffected by climate during a ride, with a user-replaceable CR2032 battery rated for 200 hours. Thread-on chainrings allow easy ring swaps without replacing the crankset. The Wide chainline suits gravel and adventure builds with wider tires, and the 42t chainring pairs perfectly with XPLR cassettes. At 172.5mm crank length, it's aimed at the performance end of the gravel spectrum. 12/13-speed compatible.

RED XPLR Power Meter is the definitive crankset for data-driven gravel racing and training at the RED tier. The lightest, most accurate power crankset SRAM makes for gravel. Requires a DUB bottom bracket matched to your frame shell (sold separately).
