TRS Plus 12-Speed Cassette

Getting the most out of your drivetrain may mean simplifying some things — like switching to a one-by crank setup, but that shouldn't come with a loss of the ever important granny gear for punchy climbs that challenge our sanity. The birth of 12-speed cassettes help mitigate that issue, and e*thirteen components push that a little bit further with the TRS Plus 12-Speed Cassette. e*thirteen has a reputation for shedding grams while packing in value, and the TRS Plus 12-speed cassette is no different. It features two 7075-precicion-machined-aluminum outer cogs, paired up with a whopping 10 ultra durable chromoly steel inner cogs, keeping weight down to a minuscule 336g for the 9-to-46-tooth version, while keeping the price palatable. The cassette features new architecture from the previous TRS Plus, opting to use a simple 3-millimeter hex wrench for assembly, and skipping the proprietary tools so it's easier to maintain. Updated shift features improve shifting, and reduce long-term wear for extended lifetime. The two-piece design of the alloy and steel cogs enable you to replace individual parts as they wear, so you don't have to toss out the whole cassette if some rough shifts take a toll on a couple of rings. The 12-speed cassettes are compatible out of the box with SRAM's Eagle drivetrains, and XD freehubs.

  • Familiarity: I've put it through the wringer

The future is here! Do you ever find yourself clicking that shifter searching for that extra high gear when charging DH lines? Thinking about getting a DH bike so you can have that smaller cog tooth, do yourself a favor and run this cassette on your trail/enduro bike. You won't find yourself searching for a higher gear again! Smooth-shifting and pairs well with Sram Eagle drivetrains. I went with the 9x50 tooth and the ratio on the gears really makes a huge difference in getting the speed you need to hit that big jump or beat that PR time you've been searching for on Strava!
