The EC90 TT is the lightest 90 millimeter deep wheelset on the market. Its 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 Diegos 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 Eastons line 90 millimeters deep and feature our proprietary Variable Nipple Bed technology which places material only where its 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 Eastons own factory.
