WIDE RANGE FOR THE PEOPLE, NOW IN 12 SPEEDS. Introducing e*thirteen's TRS Plus 12 Speed Upgrade Kit. Upgrade your 11 speed SRAM™ drivetrain to 12 speeds without needing new shifters, derailleurs, cranks, or chainrings. Why spend MORE on SRAM™’s full Eagle™ 12 speed drivetrain, when all you get is LESS range and MORE weight?


TRS Plus 12 Speed Cassette:

Our 9-46t, 12 speed cassette gives riders 511% range AND less weight by using a shorter chain and a smaller chainring to achieve similar gear ratios to other 12 speed drivetrains. Finally, a smaller chainring and more compact drivetrain increases ground clearance, while still offering more range than SRAM™ Eagle™. 

  • Replaceable aluminum and steel clusters
  • Shorter chain for weight savings vs SRAM™ Eagle™ 12 speed
  • Smaller chainring and derailleur offer more ground clearance
