Sram Rival XPLR Crank Arm 170mm Wide - Black

Think again—your eyes aren’t playing tricks. This is SRAM’s most advanced aluminum gravel crankset, engineered to punch way above its weight. The sculpted arms put material only where it matters for an exceptional stiffness-to-weight ratio, while the X-SYNC® narrow-wide chainring locks the chain in place for rock-solid retention on washboard, singletrack, and everything in between. A Wide chainline keeps things quiet and straight—and plays perfectly with Full Mount rear derailleurs. Thanks to the DUB Wide spindle, it bridges road and MTB standards for easy cross-compatibility across frames and bottom bracket shells. Ready for 135 mm, 142 mm, and Boost rear spacing and fully compatible with Eagle, Flattop D1, Flattop E1, and T-Type chains. Bottom bracket not included.
