This clever e*thirteen TRS Plus 12 Speed Upgrade Kit is designed to upgrade your SRAM 1×11 drivetrain to 1×12
Five or so years back, 1x drivetrains were fairly new, and making cheaper ones by converting existing cassettes with expander cogs was all the rage for a bit. I steered clear at the time, because it seemed like a slightly messy hack at best.
The conversion part of the e*13 12-Speed Upgrade Kit mostly happens at the shifter end though, with new innards for 11-speed SRAM GX, X1, X01 or XX1 shifters. As well as those, inside the box you’ll find a new cassette, some jockey wheel spacers, and a 12-speed chain.
Unlike with those expander cogs mentioned above, the 9-46t TRS Plus cassette is made entirely by e*thirteen. It has a 511% range, which is 10% more than SRAM’s 10-50t Eagle, and 1% more than Shimano’s new 10-51t XTR.
Thanks to a few very straight, very open downhills near me, the TRS Plus had been tempting me with a siren call something like “niiine tooooth sprooocket“. Sounds fast…

Why do you ask for registration to view some articles?
We get asked this a lot. The simple reason is that content is increasingly expensive to commission, create and publish and where once the cost of this process was mostly covered by advertising revenues, now that’s no longer the case. We increasingly rely on our paying members to keep Singletrack going and we’d love you to become one of our supporters. however, that’s not we are asking right now. You can read the rest of this feature simply by registering an account on our site.
How does being a free, registered user help you?
It’s NOT so we can sell your email details. It’s not so we can show you more ads either – in fact when you register we show you fewer ads. The reason is actually because registered users come back and look at more of our content. They start interacting with us and posting comments of their own and joining in forum discussion. That level of interaction is what eventually feeds our new subscriber numbers and so for us the journey to gaining new subscribers is to start by encouraging you to simply register an account. We hope that the benefits that will bring to you will be the first step in you joining us as a Singletrack Premier supporter.
