Constructed from aluminum, the EA70 XCT 29er Tubeless Wheels ride on years of alloy know-how from the specialists at Easton. In fact, the signature EA70 alloy rim combines the durability of aluminum with a weight that rivals some competitors' carbon alternatives.

Adding to the strength side of things, the wheels benefit from EA90 technology at the rim. If you take a good look over the rim's surface, you'll notice Easton's hallmark welding process at the seam. Also, like the EA90, the XCT uses 24 straight-pull, double-butted spokes on the front and rear, along with standard sealed cartridge bearings within the Easton X4 hubs.

Creating a UST-approved rim is tricky, but Easton found a way to get around the task of eliminating the spoke penetrations in the outer-wall of the rim. The straight-pull spokes are placed in the hub in a three-cross pattern, as per usual, but the nipple pulls double duty. In other words, it's both internally and externally threaded.

When the spokes are drawn into the nipple, they're simultaneously threaded into the inner-wall of the rim. This way, they're able to be trued exactly like a wheel with standard nipples, and only the included valve stems pierce the entire cross-section of the rim. Meanwhile, the hubs for the EA70 XCT 29-inch wheels are machined from aluminum and house standard cartridge bearings for easy serviceability. Please note that these wheels are sold as a set and are compatible with Easton's XD Driver body, which allows you to run SRAM XX1 and X01 cassettes.

initial impressions

  • Familiarity:I've used it several times

I have only had these on my new build for a couple months and less than 10 long rides but so far so good. Handling is ok, I know the enve's I rode did spin up faster and I could feel a difference but they are also 2.5k. These are a great economical way to get your bike built.

I see the comments here are regarding a rear wheel setup. Can anyone advise whether the 15x100 front wheel can be converted to a QR/100 front wheel and what parts are required?

How do the rear hubs come set up? There's only one option for 10*135/12*142 yet as i understand it, these are separate hub standards. Does it come with conversion instructions for one or the other?

Do these wheels have the X4 or X2 hubs? The tech-spec claims that they are X4 and the description says that they are X2.
