Rival E1 XPLR DUB Wide AXS 1x Power Meter Crankset

What Our Gearhead® Experts Are Saying:

"I’ve been hammering this Rival E1 crank on big gravel loops, and the left-side power meter hasn’t missed a beat. Install was super easy, battery lasts forever, and the wide chainline keeps things running quiet even on chunky tracks."

We’ve cut weight without cutting corners. The Rival E1 XPLR DUB Wide AXS 1x Power Meter Crankset brings precise power tracking to a durable and efficient 1x setup—built specifically for the terrain where boundaries blur between road and trail. By tucking the power meter into the DUB spindle, SRAM keeps weight low and protection high, giving us reliable, left-side power readings without compromise.

This crankset uses a wide 47.5mm chainline, ideal for Full Mount rear derailleurs, while the direct mount chainring with X-SYNC tooth profiling delivers confident chain retention through jarring terrain. With a sleek, re-engineered aluminum arm and up to 400 hours of ride time on a single replaceable AAA lithium battery, it’s a no-fuss, all-ride kind of setup.
