Better known for their chain guides, cockpit, and overall gravity-focus, e*thirteen is now setting its sights on slightly less-rugged affairs. Called XCX, the new line uses their decade of World Cup downhill experience to enhance your gravel or XC mountain bike. It features a host of cranks, chainrings, and cassettes with wide-range gearing to keep your bike light and shifting smooth.

e*thirteen XCX gravel and XC mountain bike components

e*thirteen is no stranger to getting dirty, though their focus has always been on big hits and heading (way) downhill. They’ve also pushed the envelope in terms of gearing, with affordable 12-speed upgrades, and the advent of the 9-tooth small cog.

While e*thirteen is far from abandoning gravity, they’re widening their product range to include XC and gravel, with the new XCX line. This includes 1x cranks and chainrings, along with all-new sizes of their popular wide range cassettes.

e*thirteen is coming out swinging, claiming that their new XCX Race crank sets are the lightest production cranks you can buy. They come as 1x only, use a 30mm spindle, and feature a self-extracting bolt. Just how light are they? Check the specs below for full details and comparison weights.

Building on their existing line of wide-range cassettes that begin with a 9-tooth small cog, the new XCX Plus line adds additional sizes: 9-34, 9-39, and 9-42. All are 11-speed, with no mention yet of 12-speed compatibility.

Each new cassette uses a mix of ten steel cogs with one large aluminum cog, for a balance of wear resistance and light weight.

In the chainring department, the new XCX Ultralight line comes in several sizes: 32, 34, 36, 38, 40, and 42 teeth. They’re made with a 5mm offset for compatibility for 1x gravel or Boost MTB drivetrains.

9-34 and 9-39 cassettes are available now, with the 9-42 hitting shelves in June 2019. Both the XCX Race cranks and Ultralight chainrings are expected to be ready in July 2019. Check out more about these and more e*thirteen hotness at the link below.

  1. Well, without a chainring, THM M3 MTB is still lighter by a couple of grams, but e13 is half the price, so very impressive. Now I know what to get when my Next SL bites the dust.

    • That was my thought after seeing the weights. When there’s no reason to develop different mounting patterns(1x, no shifting, limited sizes), I’m annoyed that we haven’t arrived at just one or two patterns. A big spline that fits over 30mm, with a common tool for lock ring.

    • Looks like Wolf Tooth and OneUp make spiders to mount their multi-bolt chainrings, but no one-piece rings compatible with e.thirteen.

  2. i wouldn’t call the XCX a “new” platform per se, e13 offerred XCX cranks (and chainguide) back when they first merged with the Hive, and i think the cranks were offered up until maybe 2012 or ’13? i have a set of the original XCX cranks, and while nowhere near this light, are amazingly stiff. glad to see this product line back.

  3. It’s been interesting to see mountain bike companies enter the Gravel market with some success (Kona, Santa Cruz, Ibis …) so it’s natural that the component companies would follow. I’ve always had really good performance from my e13 kit, so I am interested to check this out on the bike I’m about to order (Mason Bokeh, since you asked).

  4. Does the “SRAM Compatible” bit on the chainring mean that they use the same direct mount interface? Awesome stuff. I think I might be looking at a new drivetrain for the Crusher in the Tushar, now.

    • I’m guessing it just refers to the chain. SRAM has said that their 12 speed Eagle chains only work with their chainrings, but other companies have been claiming compatibility. SRAM’s direct mount interface uses 3 small screws, while e.thirteen uses a lockring.

    • I’m guessing they’re referring to the chain. SRAM has said their 12 speed Eagle chains only work with their chainrings, but plenty of other companies have claimed compatibility. The chainring-to-crank interface is 3 small screws for SRAM, lockring for e.thirteen.

    • I don’t see the Tune cranks on their site anymore, and are the other two considered to be in actual production? Just curious.

  5. Come out with a 12-speed AXS compatible 9-34 cassette and I’m sold. Could revolutionize the eTap gravel market with that shit.

  6. More 9t cogs to wear out in 10 miles. E.13 cassette design is still bad. That largest chainring looks like it’s ready to be folded over, I’m sure the smaller MTB ones are fine.

    E.13 support is great when you have problems they will help you out.
