Description

An upgrade for riding up grades.

The geniuses at e*thirteen Components have done it again, it's created a plug-and-play upgrade kit that takes your existing GX through XX1 1x11 SRAM mountain group and boosts its range with the TRS Plus 12 Speed Upgrade Kit. What's so unique and amazing about this group is it allows you to make the move to 12-speed while utilizing your existing crank, chainring, shifter, and derailleur. For much less than the price of just an X01 Eagle 12-speed cassette, you'll be 12-speed ready and it comes in at a lighter weight to boot.

Everything you need to complete the modification comes with the kit which includes the TRS Plus 9-46 tooth 12-speed cassette, 12-speed chain, replacement parts for your shifter and derailleur, and all the necessary tools. The TRS Plus 12 Speed Cassette offers an incredible 511%, versus Eagle's 500%, range, while also allowing for a straighter chainline that provides better performance and less wear. It takes around 30 minutes to install and once out on the trail, the shifting feels just as crisp as a full SRAM 12-speed group.

  • Upgrade your 11-speed 1x11 drivetrain to 12-speeds
  • Uses existing shifter and derailleur with a new cassette and chain
  • All small parts and tools are included
  • Cassette has an impressive 511% range
  • The setup additionally offers a better chainline, is lighter, and is less expensive than SRAM's offerings

Barely works.

  • Familiarity: I've used it once or twice and have initial impressions

Shifting is terrible especially the smallest 2 gears. Marginal shifting onto the largest gear. The rest of the gears work ok.


SRAM GX I installed on my wife's bike works flawlessly.

Pretty legit so far

    Picked this up last week and upgraded my 11 spd. XX1. Everything has been pretty solid so far! Stay tuned for more updates. (the cassette is seriously light.)

    Update! A couple of weeks in now, and I'm still very happy. The shift feel is a little more Shimano-esq, maybe? I've been impressed with how smooth the drivetrain runs, and I'm ready to bump up a chainring size with the introduction of the 46 tooth cog! I can wholeheartedly recommend this kit, for now.
