SRAM Eagle 90 DUB Groupset

No, the crankset included in this groupset is specifically engineered for Bosch drive units. It will not fit other motor platforms.

The single-click shifter is designed to limit the chain to one gear change per lever press. This prevents shifting under heavy load, which significantly reduces wear and tear on your chain and cassette caused by the high torque of an e-bike motor.

Yes, this groupset requires a frame with a Universal Derailleur Hanger (UDH) interface. The Full Mount rear derailleur attaches directly to the frame, bypassing the traditional hanger for increased strength and precision.

You should use the included Flattop chain. It is specifically reinforced to handle the higher torque loads and wear associated with e-mountain biking, ensuring better longevity than a standard drivetrain chain.

While it shares the 12-speed Eagle ecosystem, the specific components—particularly the derailleur and shifter—are optimized for the unique demands of this e-bike setup. Mixing and matching is possible for some parts, but for the best performance and durability, we recommend using the groupset as a complete system.

The 10-52T range provides a massive 520% gear range. This gives you a very low climbing gear for steep, technical ascents while still offering a hard enough gear for pedaling at higher speeds on flat sections.
