Easton EC90TT 56mm front+90mm rear Carbon Wheels

Our work with all kinds of athletes (including some of the best triathlete and time trial riders in the world) told us pretty clearly that many favored an aero wheel with a slightly lower profile for windy conditions or highly technical courses. After several rounds in the wind tunnel, we developed the EC90 TT 56 tubular front wheel. It features the same fast hub configuration and bladed spokes as our EC90 TT, but attached to a lighter, easier to handle, 56-millimeter-deep front rim.

The EC90 TT is the lightest 90-millimeter-deep wheelset on the market. It’s the result of our drive to create the fastest wheel possible for our sponsored road and triathlon racers. Years of engineering experience and repeated sessions at San Diego’s Low Speed Wind Tunnel have helped us create a wheelset that weighs just 1,440-grams and is unmatched in a wide range of wind conditions. The EC90 TT wheelset utilizes the deepest rims in Easton’s line (90-millimeters deep) and feature our proprietary Variable Nipple Bed technology which places material only where it’s needed to support spoke tension. The R4 TT front hub reduces frontal exposure to the wind by as much as 50-percent. Additionally the low spoke count (12-front; 16-rear) and hidden nipples enhance aerodynamic efficiency. Like every Easton wheel, the EC90 Aero is entirely hand built and acoustically tuned in Easton’s own factory.
