Restore the drive of your e-MTB with a genuine SRAM X0 Eagle E-MTB crank arm assembly, purpose-built for the high torque of pedal-assist motors. This 170 mm length suits taller riders or those who prefer more pedalling leverage, and keeps the proven strength and clean integration of the X0 Eagle Transmission system.
Why riders choose it
- Forged aluminium arm engineered to handle e-MTB motor torque
- ISIS Drive spindle interface for a secure, serviceable fit on supported e-bike drive units
- T-Type direct-mount (8-bolt) chainring interface for crisp Eagle Transmission shifting
- Self-extracting crank bolt makes installation and removal tool-simple
- 170 mm length for more leverage, suited to taller riders
Built for the e-MTB environment
The X0 Eagle E-MTB crank is part of SRAM's Eagle Transmission (T-Type) 12-speed drivetrain. Its all-aluminium construction is tuned for a balanced stiffness-to-weight ratio so power transfers cleanly under the sustained load of a mid-drive motor.
ISIS spindle and direct-mount chainring
The arm uses an ISIS Drive splined spindle interface and a T-Type direct-mount (8-bolt) chainring mount, so it pairs with SRAM Eagle Transmission direct-mount chainrings for the system's renowned under-load shifting. A self-extracting crank bolt is fitted to ease fitting and service.
Compatibility and fit
This is a replacement crank arm assembly for pedal-assist e-MTBs running SRAM Eagle Transmission. It is designed for ISIS-interface e-bike drive units, including Bosch (BDU31/SX, BDU37/CX Gen4, BDU38/CX Gen5) and Brose-based systems. The crank cap, chainring and bottom bracket are not included, so reuse your existing parts or order them separately to match your motor and chainline. If unsure of compatibility with your specific motor and frame, contact us before purchasing.
