Ultra-reliable shifting and a Full Mount derailleur power the Eagle 90 T-Type E-MTB DUB Groupset

What Our Gearhead® Experts Are Saying:

"The Eagle 90 T-Type E-MTB DUB Groupset brings SRAM’s ultra-durable Full Mount derailleur and 10-52T cassette to mechanical e-MTB shifting. Built to handle the extra torque of pedal-assist systems, this groupset provides smooth, precise shifts even under full power. The GX Eagle Flattop Chain is reinforced for longevity, and the single-click shifter prevents excessive wear. If you´re riding hard and need a drivetrain that keeps up, this system is ready for the challenge."

For those of us who push e-MTBs to the limit, the Eagle 90 T-Type E-MTB DUB Groupset delivers the smoothest and strongest mechanical shifting available. Its Full Mount derailleur attaches directly to the frame for rock-solid durability, eliminating the need for a traditional hanger. This means precise, reliable shifting under the increased torque of an e-MTB—no hesitation, no skipping, just crisp gear changes when we need them most.

The XS-1275 T-Type Cassette’s 10-52T range keeps us covered for steep climbs and fast descents, while the GX Eagle Flattop Chain is reinforced to handle high-power output. The single-click Eagle 90 shifter is optimized for e-MTB use, preventing excessive drivetrain wear while delivering responsive shifts. Whether we´re tackling technical trails or cruising at high speeds, this groupset is built to take on the demands of e-MTB riding.
