E*Thirteen Releases 12-speed Upgrade Kit for SRAM 11 Speed Drivetrains


Introducing e*thirteen’s TRS Plus 12 Speed Upgrade Kit, which allows you to upgrade your 11 speed SRAM drivetrain to 12 speeds without needing new shifters, derailleurs, cranks, or chainrings. The system is both lighter than SRAM’s current Eagle drivetrain, and less expensive. The upgrade kit relies on some new parts, all contained within the kit- including a new cassette, chain, and a shifter upgrade kit.

The components:

TRS Plus 12 Speed Cassette: This 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.

  • Replaceable aluminum and steel clusters
  • Shorter chain for weight savings vs SRAM™ Eagle™ 12 speed
  • Smaller chainring and derailleur offer more ground clearance
  • 336 grams
  • 9-46t cassette (9, 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 46)
