SRAM Force AXS E1 DUB Wide Left Crank Arm w/Power Meter - 160mm
Accurate power data. Your choice of fit — Standard road or Wide gravel.
The SRAM Force AXS E1 DUB Left Crank Arm with Power Meter puts Quarq power measurement directly into your drivetrain without adding a spider or a second chainring interface. Spindle-based measurement means fewer moving parts, consistent accuracy across the pedal stroke, and seamless integration with SRAM Force AXS electronics. Available in Standard (road 2x) and Wide (gravel/adventure 1x) formats so you can match the crank to your actual build — not just whichever version happened to be available.
Standard vs Wide: what to choose. Standard uses a 73mm Q-factor, designed for SRAM Force AXS 2x road drivetrains. Wide uses a 91mm Q-factor, optimised for 1x gravel and adventure setups where chainline geometry demands more stance width. Both use the same DUB spindle and bottom bracket interface. Choose based on your drivetrain configuration.
What makes this worth it
Quarq Spindle Technology
Power measurement lives in the DUB spindle itself, giving you clean integration with any Force AXS chainring configuration without adding a separate spider unit or external sensor.
Standard and Wide Variants
Standard suits road 2x builds at 73mm Q-factor. Wide suits gravel and 1x setups at 91mm. One listing, two geometry options — same DUB bottom bracket either way.
Native AXS Integration
Designed to work within the SRAM AXS ecosystem from the ground up. Power data feeds natively into the AXS app for firmware updates, calibration, and ride history — no third-party bridges.
Dual Wireless — Every Head Unit
Broadcasts ANT+ and Bluetooth Smart simultaneously. Pairs with Garmin, Wahoo, Hammerhead, Polar, and any other compatible head unit with no dongles or adapters required.
700+ Hour Battery Life
Runs on a standard CR2032 coin cell rated for 700+ hours. That covers roughly 18 months of weekly long rides on a single battery — easy to source anywhere in the world.
Left-Side Power Measurement
Measures left-leg output and doubles it for a total power figure. Reliable for training load tracking, FTP testing, and interval pacing where watt trends matter more than absolute left/right symmetry.
