The exclusive-to-e*thirteen 9t sprocket allows you to run a smaller chainring for better ground clearance and additional weight savings.

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.

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.

* Note for Eagle™ AXS users: TRS+ cassettes were developed before Eagle AXS was available in the market, so TRS+ Cassettes may present setup problems in some cases. For best results we recommend Helix 12s Cassettes for use with Eagle AXS drivetrain!
