- 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.
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.
