Leave it to Easton—the composites experts—to create the first zero compromise carbon fiber road clincher. The EC90 SL offers the very best braking performance in carbon rims. Period. We did it with the help of our exclusive ThermaTec™ brake track treatment, available only on Easton’s composite clincher wheels. ThermaTec brake track treatment provides smooth, easily-modulated braking power and reduces heat build-up under heavy braking. Of course ThermaTec is only one highlight of the EC90 SL. The 38-millimeter deep carbon rim is molded into its final shape in one process, ensuring superior strength and impact resistance. The EC90 SL is the only composite 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 Fahrenheit. Every EC90 SL is entirely hand-built and acoustically tuned in Easton’s own factory.
The tubular version of the EC90 SL takes many of the same great features and brings weight down to 1,250-grams. These wheels are strong enough to handle Spring Classics like Paris-Roubaix yet light enough to win mountain stages of the Grand Tours. The EC90 SL is the one race wheelset to have if you can have just one. Thanks to a 38-milimeter deep rim and a low spoke count, the EC90 SL strikes a perfect balance between a light climbing wheel and a set of aerodynamic TT hoops.

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.
