Go big.

When you bought your stock enduro rig a couple of years ago, you had no idea how big cassettes and gear ranges were about to get. If you're looking for an after-market option that'll expand your shifting options without requiring you to buy a new drivetrain, take a look at e*thirteen components' TRS Plus 11-Speed Cassette. With a whopping 9-44 tooth span — yes, that includes a rare 9-tooth cog — this behemoth cassette will give you miracle gears when you ask for them and the chance to accelerate hard into a descent, if your legs can keep up. Plus, it comes set up for an XD Driver body, so it's easy to swap between your quiver of bikes or to a future upgrade.

  • Upgrade your shifting with this expansive new cassette
  • Huge 489% gear range gives you more options for more terrain
  • Durable aluminum and steel cogs can take trail abuse
  • Mounts to XD driver body and Shimano/SRAM 11-speed drivetrains
  • Replacement cogs sold in small groups for inexpensive repairs

Good not great

  • Familiarity: I've put it through the wringer

I bought this last season and have put considerable miles on it. Initial impressions were great—light, easy set-up, well made, and it looks awesome. The riding where I live is steep, so I love the 44t and rarely use the bottom range. However, the 9t on the low end definitely gives the pedal stroke a rough feel—almost like the cog is a hexagon instead of a circle. The only other critique I have is that you really need to stay on top of replacing your shifter cable. After a very minute amount of stretch, the shifting gets a little less reliable. I had an 11spd SRAM cassette prior and that seemed to be a lot more reliable and less sensitive. I don't know if it has something to do with the spacing of the cogs and if e13 didn't get the 1:1 ratio exactly right or what. All in all a solid component, although for the price it seems like sticking with SRAM may be a better way to go.

  • Familiarity: I've used it several times

so far so good with this cassette. Its amazing how different my bike climbs with the extra gearing. Installing this on a sram freehub body, and drivetrain was easy. I have a medium cage derailleur which doesn't have any problems getting around that 44t cog. As long as this holds up it is my solution to climbing but not running out of gears on the DH. I am only a few weeks into using it so feel free to reach out with questions and i will update this if anything changes .
