EC90 AERO 56MM CLINCHER
EVERYDAY AERO RACE WHEELSET
This is the ultimate, every-day aero wheel. The EC90 Aero is fast enough to win time trials, stable in windy triathlons and untouchable in long breakaways. This is the first and only zero compromise carbon fiber road clincher to feature wind-cheating aerodynamics. The EC90 Aero Clincher combines the unbeatable braking performance of Easton’s proprietary ThermaTec™ brake track (providing smooth, easily-modulated braking power) with a fiercely-fast 56-millimeter tall rim.
In addition to the tall rim profile, EC90 Aero wheels feature a low spoke count (18-front; 20-rear) and hidden spoke nipples (tubular only) providing a significant, wind cheating advantage. Best of all these wheels offer dependable handling in a variety of conditions. Thanks to their depth and durability, the EC90 Aero has also become a favorite of cyclocross racers as well as classics veterans like George Hincapie (Team BMC Racing). Sealed R4 SL hubs with alloy axles, alloy freehubs and ceramic bearings round-out the package on these top-notch race wheels. Like every Easton wheel, the EC90 Aero is entirely hand built and acoustically tuned in Easton’s own factory.
The EC90 Aero is the only carbon clincher rim to survive tests in our laboratory for impact and fatigue resistance as well as our brake track torture test, handling temperatures up to 500 degrees F. Every EC90 Aero is entirely hand-built and acoustically tuned in Easton’s own factory.

100% HANDBUILT
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.
