Gravel power data, no compromises — Rival AXS XPLR with built-in power meter.
The SRAM Rival AXS E1 XPLR Crankset brings power measurement to the mid-range of SRAM's wireless road ecosystem. Built specifically for 1x gravel drivetrains, it pairs a DUB Wide spindle with an integrated power meter so you get accurate watt data on every ride — without adding pedal-based hardware or a separate unit. The 42T Direct Mount chainring is included, tuned for XPLR's long-range gearing philosophy. Bottom bracket not included.
DUB Wide — not the same as standard DUB. This crankset uses the DUB Wide spindle interface, which requires a DUB Wide bottom bracket. It is not interchangeable with standard DUB BBs. Verify your frame's shell compatibility before ordering.
What makes this worth it
Spindle-Based Power Meter
Power measurement is built directly into the DUB Wide spindle — no pod, no pedal swap, no additional hardware. Watts come from the crankset itself.
42T Direct Mount Chainring
Included 42T Direct Mount ring delivers clean chainline, reduced weight, and fast chainring changes. Optimised for XPLR's wide-range cassette pairings.
XPLR Gravel Geometry
Crank geometry and Q-factor are engineered for the demands of long-distance gravel riding — wider stance for stability, designed around mixed-terrain cadence patterns.
Full AXS Integration
Pairs natively with Rival AXS derailleurs via the AXS app. Monitor power, calibrate, and update firmware wirelessly from your phone or head unit.
DUB Wide Interface
The wider tread DUB spindle delivers improved lateral stiffness under load — especially noticeable on steep climbs and technical terrain where power transfer matters most.
Five Crank Lengths
Available in 160, 165, 170, 172.5 and 175mm arm lengths. Choose based on your inseam and riding position — shorter lengths suit riders with hip flexibility issues or those transitioning from road.
