The $799 EA90 AX wheelset ups the ante from the existing EA70 AX wheelset. The wheelset adds 1mm extra internal width, with a 25mm-wide rim. It’s 21mm deep, and 29mm externally wide.

It’s also about 140 grams lighter than the EA70 AX, at 1625g list weight. Our actual measurements reveal our pair weighs 1630g with tape and valves.

How does Easton achieve the weight savings? It swaps the EA70 AX’s brass nipples for DT alloy nipples, adds Sapim double butted straight pull spokes and rotates on the company’s top-shelf CenterLock Vault hubs.

Tubeless setup is a snap, literally. We easily mounted a 43mm Panaracer GravelKing SK and a 42mm Soma Fabrications Cazadero tire without tire levers, and a compressor pump snapped both into place. With Panaracer’s new Smart Seal sealant, the Cazadero has been airtight since the initial blast, while the GravelKing took one top-off before remaining airtight.

The 25mm width helps add air volume and support the sidewalls of 40+mm gravel tires. At 35 psi, the 42mm Cazadero measured 43.8mm, while the 43mm GravelKing measured 43.3mm.

Like Easton’s other wheelsets, the EA90 AX wheels are compatible with major axle configurations, including QR, 15mm or 12mm front, and 142x10mm rear through tool-free axle cap swaps (included).
First rides have proven burp-free. We’ll see if they hold up to the rigors of the Lost Sierra. Stay tuned for a full test.
Official product launch info below:
The EA90 AX wheel joins our popular AX Series lineup, giving you the all road advantage on a lightweight EA90 aluminum rim. With a 25mm internal measurement and 3mm of offset, you’re ready to mount your favorite gravel and road plus tires to get the most out of the path less traveled.
EA90 AX wheels are laced with our new Vault hub – designed to exceed your needs from tarmac to singletrack. Larger bearings on a wider bearing stance and improved seals help to push reliability to a new level. A reversed drive ring configuration gives 60 points of engagement at just 6-degrees for instant acceleration.
Included in the box are tool-free swappable end-caps for all major axle standards and 5 extra straight-pull Sapim spokes (shipped with rear wheels) that match the uniform spoke length throughout both wheels. With center lock discs and easy tubeless ready setup, the EA90 AX wheelset is adventure ready.
