The spindle is where crank stiffness either holds or folds. SRAM's Force AXS E1 DUB Wide Crank Arm Assembly uses their hollow forged aluminum construction with the DUB spindle system, giving you the interface compatibility and torsional rigidity that matters when you're putting power down. This is the crank arm set only—no chainrings, no spider—so you're getting the foundation for a 2x wide chainring setup without paying for rings you might already have or want to spec differently.

The wide designation refers to chainring spacing, not Q-factor. These arms position the chainrings for proper chainline with SRAM's 2x road drivetrains, working with Force or Red AXS wide direct mount chainrings. The DUB bottom bracket interface threads into whatever shell standard your frame uses—BSA, T47, PF30, BB30, PF86—you just need the matching DUB bottom bracket for your frame.

Hollow forging keeps weight competitive without sacrificing the beam strength that prevents flex under hard efforts. The self-extracting crank bolt simplifies installation and removal, eliminating the need for a separate puller tool. Arm lengths run from 165mm through 175mm in 2.5mm increments, covering the full range of fit preferences and riding styles.... Read More
