Overview

What is the SRAM Eagle 90 T-Type Groupset 165mm?

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 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, and is the most rebuildable Eagle Transmission derailleur ever made, with replaceable 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. 32t chainring.

This is the 165mm crank arm version. SRAM's own advice on crank length is simple: shorter arms help minimize pedal strikes on a bike with a low-slung bottom bracket.

What is the advantage of the 165mm crank length?

The 165mm version is identical in all other specifications. SRAM's guidance is that shorter crank arms help minimize pedal strikes on a bike with a low-slung bottom bracket, while longer arms suit riders who like the feel of spinning big circles.

Is this groupset E-MTB approved?

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 compatibility is required for the Full Mount derailleur?

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