e*thirteen TRS Plus 12 Speed 9-46T Cassette

Perfectly suited for high-power e-MTBs, the TRS+ 12sp 9-46T Cassette is a tough, lightweight, and affordable solution that excels in demanding conditions. Close-ratio gearing and an exceptional 511% range ensures smooth shifting under torque, making it perfect for electric and analog mountain bikes.

The TRS+ Cassette plugs directly into SRAM™ Eagle™ Mechanical and Shimano™ XTR™, XT™, and SLX™ 12sp shifter and detrailler combinations. Its exclusive 9T sprocket allows you to run a smaller chainring, enhancing ground clearance and reducing weight.

A two-part construction further reduces weight and allows for the individual replacement of alloy or steel clusters, saving money and reducing waste.
