Overview

What is the SRAM Eagle 90 T-Type Groupset?

The SRAM Eagle 90 T-Type Groupset is the world's first mechanical groupset built on the Full Mount Eagle Transmission architecture. It delivers unprecedented shifting under maximum power, a defining capability of the T-Type platform, with a mechanical shifter that provides a satisfying, positive click on every gear change. The Eagle 90 derailleur uses a Full Mount Hangerless Interface for maximum impact resistance with no hanger to bend or break, and is the most rebuildable Eagle Transmission derailleur ever made, with replaceable B-Knuckle, parallelogram links, skid plates, cage, and cage assembly. Includes a forged aluminum DUB crankset with removable bashguards, XS-1275 T-Type cassette (10-52t), and GX Eagle Transmission Flattop chain. Setup is a simple four-step process: prepare, hang, tighten, tension cable. 32t chainring, 170mm crank arms.

Eagle 90 is for riders who prefer the feel of mechanical shifting but want the Full Mount toughness and zero-guesswork setup of the Transmission platform.

What is the difference between Eagle 90 T-Type and AXS T-Type?

Eagle 90 T-Type uses mechanical cable shifting with a positive click, while AXS T-Type uses wireless electronic shifting. Both use the Full Mount Hangerless Interface, T-Type cassette, and Flattop chain. The mechanical version has no batteries to charge.

Is Eagle 90 T-Type approved for e-MTB use?

Not as sold. This groupset comes with the double-click Eagle 90 shifter, which SRAM says is not compatible with E-MTB. SRAM says a dedicated single-click shifter variant is required for E-MTB use, and it sells a separate Eagle 90 E-MTB groupset.

What frame dropout does Eagle 90 require?

Eagle 90 needs a UDH frame. SRAM lists it for Hangerless Interface (UDH) frames only. The Full Mount attachment centers the derailleur on the rear axle, so there is no hanger to bend or break.
