ethirteen TRS Plus 12 Speed 9-46T Cassette Info

TRS Plus 12 Speed 9-46T Cassette is built to thrive under torque-heavy riding, making it a dependable choice for e-MTBs while remaining an excellent option for aggressive analog trail bikes. Designed around close-ratio gearing and a wide usable range, this cassette delivers controlled cadence and consistent shifting in demanding terrain.

The 9–46T spread provides an impressive 511% range, balancing tight steps through the mid-gears with a bailout low gear for steep climbs. The distinctive 9-tooth smallest cog allows riders to run a smaller chainring, improving ground clearance while reducing overall system weight. This makes the TRS Plus cassette especially effective for technical riding where pedal strikes and drivetrain efficiency matter.

Compatibility is straightforward and rider-friendly. The TRS Plus cassette integrates directly with SRAM™ Eagle™ mechanical systems as well as Shimano™ XTR™, XT™, and SLX™ 12-speed shifters and derailleurs. An XD driver is required for installation. For riders using Hope™ hubs with XD drivers, an additional shim is needed to ensure proper fit and is included when specified.

Durability and serviceability are core to the design. The two-part construction combines alloy and steel clusters to manage wear while keeping weight in check. Individual clusters can be replaced as they wear, extending cassette life and lowering long-term maintenance costs.
