When the pace goes from hard to ridiculous, you'll be glad you have Easton's EC90 Aero 55 wheels mounted to your steed. These carbon wonders boast 55mm-deep rims with Easton's Phantom profile to provide an extreme aerodynamic advantage no matter which way the wind blows. They're light too, so you can throw down with authority on the climbs. Plus, they feature smooth Echo hubs that provide a virtually frictionless ride. And, the EC90s are hand built with bladed Sapim spokes for that extra touch of fast that's perfect for when the pace ratchets up to ridiculous.
