E-Thirteen’s all-new TRS+ Cassette offers impressive 511% range, an unbeatable value at and crisp shifting performance on both SRAM and Shimano drivetrains. Using a unique two-piece assembly and our exclusive 9t cog, the TRS+ cassette offers a massive 9-46 tooth range, which means you can clean steeper climbs, and then blast the descents! As common with other drivetrains, a larger rear cassette also means a larger chainring up front…aka, less ground clearance. An advantage of the TRS+ Cassette is that our 9-46t range accomplishes the same gearing, but with a smaller front chainring and MORE ground clearance, something even more important on today’s “long, low, slack” bikes. The largest cogs are precision machined from aluminum and attach to a SRAM XD driver body. The remaining eight steel cogs lock into place with a chain whip. Both parts of the TRS+ cassette are individually replaceable and available individually, which means that replacing worn parts is possible without buying a whole new cassette. More range, more fun, same standard.
