The EC90 TT is the lightest 90-millimeter-deep wheelset on the market. It’s the result of Easton's drive to create the fastest wheel possible for their sponsored road and triathlon racers. Years of engineering experience and repeated sessions at San Diego’s Low Speed Wind Tunnel have helped Easton 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 their 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. Cassette Body Compatibility Chart
