Easton EC90 TT 90mm Road Rear Wheel

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 (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.

Easton EC90 TT 90mm Road Rear Wheel Technology:

100% Handbuilt

We didn’t always make wheels, but once we started, we knew there were a few things that every Easton wheel would have to do: be durable, fill a specific purpose (like work great for the demands of trail riding), meet our stringent testing standards and stay true under conditions that reduce most wheels to something like a puddle.

In order to guarantee durability and incredible trueness, every wheel that you’ll see from Easton is 100% hand built and trued using our proprietary acoustic method. That’s right, our trained builders don’t judge a wheel as straight and round simply by watching it glide through a truing stand. No, they listen to the tone that each spoke makes when plucked. Even tones make for a wheel that’ll stay straight and round much longer than other methods.
