The SRAM GX Eagle Transmission DUB crankset balances performance and value for the T-Type Eagle platform — two crank arms built for stiffness and efficiency, with DUB spindle compatibility across the full range of SRAM bottom bracket standards. No-nonsense construction that delivers what a 12-speed Eagle drivetrain needs without paying for materials beyond what the job requires.

Highlights

• GX Eagle Transmission (T-Type) crankset for 12-speed Eagle T-Type drivetrains
• DUB spindle — compatible with SRAM's full range of DUB bottom bracket standards
• Stiff, efficient crank arm construction at GX groupset level
• Designed for SRAM Eagle T-Type direct mount chainrings
• Available in multiple arm lengths and chainring sizes

DUB spindle compatibility

The DUB spindle's 28.99mm diameter is stiffer than traditional 24mm designs and works across SRAM's entire DUB bottom bracket range — BSA, PF30, BB30, T47, and more. This gives the GX Eagle crankset broad frame compatibility, fitting the vast majority of MTB frames without needing a different crank for different BB standards.

Fit and compatibility
