Hacked: e*thirteen's 11 to 12-Speed Drivetrain Conversion 9

How to modify your older SRAM drivetrain to work with 12-speeds and gain lots of gear range in the process

 

The problem solvers over at e*thirteen have come up with a way to get more life out of the SRAM GX, X1, X01, or XX1 11-speed drivetrain components that you probably paid good money for not long ago. Thanks to a bit of clever reverse engineering and a few replacement parts, the TRS Plus upgrade kit allows you to convert 11-speed SRAM shifters and derailleurs to 12-speed. Included in the kit is a new 12-speed TRS Plus cassette with a whopping 511% gear range, plus all the necessary tools to complete the job.

It's an involved process, but if you know your way around a bike, take your time, and follow our video tutorial, we're confident you can handle it. We think this is a worthwhile upgrade for those looking to spin a little easier and squeeze the most life out of their gear.
