Posted by Logan Watts

Now you can convert almost any SRAM 11-speed drivetrain to a 511% 12-speed using e*thirteen’s all new TRS Plus 12 Speed Upgrade Kit. The kit includes a 12-speed cassette, chain, and parts to upgrade your SRAM 11-speed shifter and derailleur. Here are the details and photos of each element:

TRS Plus 12 Speed Cassette

The new TRS Plus 9-46T 12-speed cassette offers a 511% range and should save weight over other 12-speed drivetrains by using a shorter chain and a smaller chainring to achieve similar gear ratios. Like the 11-speed TRSr and TRS+ cassettes, e*thirteen’s new 12-speed cassette features two clusters: a one-piece set of 10 steel cogs and an aluminum cluster with the two largest chainrings.

    The new NX Eagle Groupset is $270 excluding the crankset, which you don’t need if you’re upgrading from an 11 speed groupset. That means you can have a complete non-hack solution for less than this. e*thirteen was a few months late getting this to market.

  • Ben Skoning

    What about those with XX/XO stuff they want to upgrade with out dropping in component quality?

  • Dave Guerette

    Yes, except NX is made out of mostly plastics, doesn’t work as well and weighs twice as much as XO1/XX1. NX is great for an entry level bike and works well enough, but nobody is upgrading their xx1 11 speed bike to NX eagle. But a lot of people will do this upgrade, and get MORE gear range, and also save a few grams over the top end eagle set up.
