- 32-38-44t Aluminum cogs for TRS 9-44t 11 speed cassette
The HELIX R Cassette is an upgrade to any SRAM™ Eagle™ or Shimano™ drivetrain, with more range than any other cassette on the market. The 9 tooth cog lets you step down one chainring size while keeping the same top end gearing and provides not only better ground clearance, but an overall lighter drivetrain.
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.
TRS Plus 12 Speed Upgrade Kit. Our kit lets you upgrade your existing 11 speed SRAM™ drivetrain to a 12 speed drivetrain without needing new cranks, chainrings, shifters, or derailleurs.
The TRS Plus 12 Speed Cassette offers the same 511% (Eagle™-beating) range, an unbeatable value, and crisp shifting performance on SRAM™ drivetrains.
Why spend MORE money on SRAM’s™ full Eagle™ 12 speed drivetrain, when all you get is LESS range and MORE weight?
So, why buy this over Eagle™?
– You don’t need a whole new drivetrain…just our cassette and shifter.
– Keeping your existing 11 speed SRAM™ drivetrain gives you better ground clearance in both the chainring and derailleur.
– The smaller 11 speed derailleur, chain, chainring, and cassette are SIGNIFICANTLY lighter than Eagle drivetrains.
– The 9-46T cassette has a straighter chainline in comparison to Eagle™, for a longer-lasting drivetrain.
What’s in the box: TRS Plus 12 speed cassette, 12 speed chain, upgrade parts for your shifter and derailleur, and all the necessary tools
Special Note for Hope™ Hub Owners: Please notify us in your Order notes if you will be installing the cassette on a Hope™ XD driver. Hope™ XD drivers do not adhere to the XD specification and require an additional shim which we will include with your order.
