More range, less weight, and less money. Need we say more?

Our TRS Plus 12 Speed Upgrade Kit lets you upgrade your existing 11 speed SRAM™ X1™, GX™, & XO1™ drivetrain to 12 speeds without needing new cranks, chainrings, shifters, or derailleurs. The exclusive-to-e*thirteen 9t sprocket allows you to run a smaller chainring for better ground clearance and additional weight savings.

Not compatible with XX1

Special Note for Hope™ Hub Owners: Please notify us if you will be installing the cassette on a Hope™ XD driver, as Hope™ XD drivers do not adhere to licensed XD specification and require an additional shim which we will include with your order.

If you're planning on building up your new bike with a 12 speed drivetrain or your existing setup is running rough, consider saving some money and weight with e*thirteen's TRS Plus 12 Speed Cassettes.
