Show Description

This groundbreaking upgrade kit lets you convert your existing 11-speed SRAM™ drivetrain to 12-speed, with a larger gear range than SRAM's vaunted Eagle™ group set. The impressive RS Plus 12 Speed cassette provides a huge 511% gear range that will help you up the steepest climbs. Spending a lot of time in the 46? The cassette can also be separated into three parts, allowing you to switch out worn sections instead of replacing the whole thing.

  • 7075 aluminum and one-piece heat-treated cromoly steel construction.
  • 511% gear range.
  • Compatible with SRAM™ GX™, X1™ and XO1™ 11-speed drivetrains.
  • 9-46T cassette has a straighter chainline than Eagle™, and weighs less.
  • 9-10-12-14-16-18-21-24-28-33-39-46.
  • Kit includes TRS Plus 12 speed cassette, 12 speed chain, upgrade parts for your shifter and derailleur, and all the necessary tools.
