Think you know fast? You don’t know fast, not until you’ve tried these new SES 7.8 aero wheels. That’s what ENVE says anyway, and while we haven’t hit the road with them yet, we can say that they bring some interesting thinking for road racers and triathletes.
You see, they aren’t the deepest wheels ENVE have ever produced, nor the lightest, but they are designed to offer maximum aero performance and stability. Particularly when paired with a modern aero frame and large 25mm tyres.

Here comes the science
The SES 7.8 features asymmetric rim geometries front to back, with a front rim that’s 71mm deep and 29mm wide, while the rear rim is 80mm deep and 27.5mm wide. What’s more, they also have dissimilar sidewall curvatures, due to their differing depths (see cross section above).
Wait, what? "Wheels only work in a bicycle frame," said SES founder and aerodynamicist Simon Smart. "To test and develop wheels in isolation from the rest of the system does not answer the right question. The question we are answering is: how do you make the entire system more efficient?
The numbers
