XCX Plus 11 Speed Cassette

It seems like mountain bikers often get to have all the fun when it comes to new tech, but we'd argue that gravel riders experience some of the more grueling climbs, and jarring descents of the cycling world. To get the most out of both sides of the ride, E*Thirteen crafts the XCX Plus 11 Speed Cassette with a tiny 9-tooth cog for powering down steep pitches, and a few different big-ring options ranging from 34-to-42-tooth, enabling you to tune your ride for the terrain you tackle the most. The cassettes feature ten steel cogs to boost durability, plus one alloy cog that keeps the weight down.

  • A cassette built to take 11-speed to gravel and XC rigs
  • 9-tooth small cog provides major power on descents
  • A variety of cassette ranges lets you tune to your riding needs
  • Steel construction on 10 cogs elevates durability
  • Single aluminum cog minimizes weight where you need it
  • Two-piece construction enables part replacement as needed

Versatile gear spread for gravel bike

I've put it through the wringer
Size Bought

I think this is a great product that fits a niche for riders like me. I ride a 1x gravel bike in Florida with, at best, terrain that would be considered rolling hills. I needed an XD compatible replacement for the SRAM 10-42 XG-1150 and wanted something without the big spread of gears that I found I didn’t need. Installation is fairly easy, but different compared to normal HG or XD cassettes, torque wrench recommended. It’s lighter compared to the SRAM XG-1150 and considerably less money than a XG-1190. I’m using a KMC chain and the shifting hasn’t changed. The 9-34 XCX has been pretty much perfect for what I wanted. I wish I’d discovered this cassette sooner.


Does the 9x39 work just with 1x11’s or can it be used in a standard cyclocross 2x11? Currently running a 11x32 cassette but since moving to Colorado I want a much bigger range.
