Overview

SRAM Eagle 90 Transmission is the mechanical, cable-shifted 12-speed T-Type groupset with hangerless Full Mount derailleur and shifting under E-MTB power.

Eagle Transmission is SRAM's T-Type 12-speed 1x system: Full Mount derailleurs bolt directly around the rear axle with no hanger, and cassette mapping plus X-Sync tooth profiles give, per SRAM, the best shift under load – even with the added power of E-MTB. All T-Type components can be mixed and matched.

Eagle 90 Transmission is, per SRAM, the world's first mechanical groupset with Full Mount toughness: a rebuildable derailleur with Trailside Reset, a forged aluminium crankset in 155–175 mm arm lengths and a parallel-to-the-bar mechanical shifter that pairs with stealth SRAM brakes.

  • Mechanical shifting with Full Mount, no derailleur hanger
  • 44 shifting points on T-Type cassettes for shifting under E-MTB power
  • Rebuildable derailleur with Trailside Reset
  • Forged aluminium crank, 155–175 mm in 5 mm steps
  • "Prepare, hang, tighten" setup
