Easton EC90 TT Carbon Tubular Wheelset
Easton’s proprietary narrow-flange R4TT front hub reduces frontal spoke area by 50% for improved aerodynamics. Combined with a new wind tunnel-tuned 90mm rim, and the new EC90TT displays lower drag than the Zipp 808 at 0, 5, 10, 15 and 20 degree yaw angles. It even rivals the much deeper (and heavier) Zipp 1080 at 5 and 15 degrees.
At 1424 a set, the EC90 TT is a full 30 grams lighter than the Zipp 808, and still 9mm deeper in rim profile, thanks to Easton’s Variable Nipple Bed (VNB) Technology. This process of internally tapering the rim bed eliminates excess carbon between spoke holes and allows for a sharper inner edge. Less weight, improved aerodynamics with no loss in strength.
There are two ways to make a wheel fast in the wind. One is to design the leading (forward) edge to help smooth the path of the air around the tire. Zipp’s bulged rim profile attempts to do this. The other way to design a fast wheel is to focus on sharpening the rim profile on the trailing edge to manage the air as it exits the rear edge of the wheel. You can’t have it both ways. At Easton they feel you can design a faster wheel with a sharper, narrower profile like the EC90. And Easton's wind tunnel data confirms this.
