Meeting the need for speed.
Upgrade that new aero frame and get the most out of your TT efforts with the ENVE SES 7.8 Carbon Road Clincher Wheelset with ENVE Hubs. Since the 7.8s are billed as ENVE's fastest rims, it's only fitting that they're paired with the low weight and ceramic bearings of the manufacturer's carbon hubs. The rims are also designed with the current trend of wider tires in mind, so they generate maximum aerodynamic benefit when paired with the 25mm tires favored by the pros.
While going forward fast is important, ENVE recognizes that aerodynamics amount to naught if poor braking sends you off the road. To address this, the 7.8 incorporates ENVE's new molded-in, textured brake surface, which was first launched with the climbing-specific SES 2.2 wheelset. When paired with the included ENVE black brake pads, the new brake track nets a claimed 30% improvement over ENVE's previous brake track and pad combinations in conditions ranging from wet to dry. When you're carrying speed into corners and rolling into unexpected weather, it's comforting to know you can trust the braking surface to do what it's supposed to do.
Like the rest of ENVE's SES line, the 7.8 rims aren't subjected to static, arbitrary NACA shapes. Instead, the engineers let each wheel's depth requirements dictate the ideal dimensions in order to reduce lateral forces and increase aerodynamic benefits across a wide range of yaw angles. This approach is apparent in everything from the rim's rounded inner face to the different dimensions of the front and rear wheels.
Of course, we also recognize that aerodynamics and handling are absolutely meaningless if a wheelset crumbles at the first sign of less-than-optimal road conditions, so we expect ENVE's obsessive engineering to carry over into the wheels' materials and layup. ENVE routes the fibers around each hole in a 100% intact design — no cutting, machining, or drilling required. By continuously wrapping the fibers, ENVE adds strength, boosts rigidity, and allows for less material and a lighter rim. The use of a removable bladder also keeps weight down compared to other wheels, so the SES series boasts the highest claimed strength-to-weight ratio on the market.
As mentioned above, these SES 7.8 rims are laced to the all-new ENVE carbon hubs, which feature DT Swiss' venerable star ratchet engagement system. Unlike the standard 240s, though, the carbon hubs are built with CeramicSpeed bearings instead of stainless steel, putting them more on par with DT's 180 hubs. The hubs' weights also compare favorably to the top-end kit, with the carbon hubs weighing 74g (front) and 158g (rear) for a total claimed weight of just 232g — 92g lighter than DT's 240 set.

Big, Loud and FAST!
- Familiarity: I've put it through the wringer
I have now spent much quality time on these guys equipped with the DT/Swiss 240 hubs and have definitely figured a few things out:
They seem *enormous* at first, but that initial shock goes away quickly, certainly once you get them up to speed and realize the difference they make in keeping you at speed! On flat-to-rolling roads, they are amazingly fast and smooth. Climbing-wise, I've been pleasantly surprised much like I was with the outgoing Enve 6.7. The 7.8's are claimed lighter, so that's even better news. The "whoosh" sound that some of us love about deep-section wheels is even more pronounced than with the 6.7's too. In a dead-out sprint, the folks you're about to blow past will definitely know you're coming! The Enve Carbon Hubs, from my experience with my 4.5, are outstanding! This isn't a wheelset where one should be too concerned with weight, but you will save some grams. The low rolling resistance and smooth, reliable (DT internals) performance are definitely worth the upgrade if you can swing it.
Once pointed downhill, watch out! You'll hit your terminal velocity faster than you have before, but the updated brake surface can handle the 50-0 work remarkably well. I learned this on my 4.5's and it holds true on these. Fast, technical descents do require more care at first, until you get a solid feel of how these wheels corner. Long, sweeping or decreasing radius corners are not their absolute forte, but they are brilliant in fast, tight, flat (think: criterium course) corners. The ease of acceleration after said corners is impressive as well.
They are Tubeless-Ready, but I had a less-than-optimal experience with them setup tubeless (Reach out to me directly for details).
I have ridden them with both Vittoria Corsa-G speed and Continental Grand Prix 4000-S II tires, with a variety of pressures. *Always* use the Enve new-style brake pads.

Does the wheels fit on 2015 Cervelo S5?
Can these wheels be set up with tubeless clinchers?
Yes, I believe they actually come tubless ready.
