Take a close look at the EA90 Aero (alloy) and you’ll notice two different rim depths—a 28-millimter deep front rim and a 32-millimter rear. These rim profiles were designed for high performance riding and racing on flat to rolling roads and strike a great balance of aerodynamics and dependable handling. You’ll go fast on the EA90 Aero, but you’ll still be able to stop on a dime thanks to the Gen 4 aluminum rims’ machined brake track. And there’s more to these wheels than a fast set of hoops: the EA90 Aero features high-quality Sapim double-butted, straight-pull spokes (with alloy nipples) as well as R4 hubs that run trouble-free sealed bearings. Like all Easton wheels, the EA90 Aero is hand-built and acoustically tuned in Easton’s own factory.
