SES 7.8 Wheelset
Triathletes and road racers sometimes appear to reside in vastly different worlds, but one thing we can all agree on is that saving watts and gaining speed is essential to fast times and epic race stories. Aerodynamic wheels are a huge part of that equation, and you can't get much faster than the SES 7.8 Wheelset from ENVE. It's ENVE's fastest wheel system to date, and these wheels are built for maximum benefit when running 25mm tires, the peloton's new choice.
While moving forward quickly 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. ENVE builds the hoops to a wide stance that optimizes aerodynamics with a 25mm tire while also boosting tire volume, which in turn allows lower tire pressure for a smoother, more efficient ride. We'd also happily run even wider tires for an extra dose of plush, and swapping the tubes for tubeless will take full advantage of the new rim width by reducing pinch flat risk while further reducing pressure and rolling resistance.
These wheels are built using the Smart ENVE System (SES) to create a rim that is as strong and stable as it is aerodynamic. ENVE wheels enjoy the reputation of having one of the highest strength-to-weight ratios in the industry because of a jealously guarded process of molding in spoke holes, nipple seats, and valve stem holes rather than drilling them after the fact. ENVE routes the carbon fibers around each hole to maintain continuous fiber integrity, which results in both increased rim rigidity and lower weight. ENVE is also able to remove the inner bladder once the molding process is complete, which results in a lower overall weight than processes that leave the bladder in place. This is a lengthy and costly extra step, but it results in a wheel that is perfectly tensioned and significantly lighter than it would be were the bladder left inside.
These SES 7.8 rims are laced to the all-new ENVE Alloy hubs, which feature Mavic's venerable ID 360 ratchet engagement system. Using robust NTN stainless steel bearings and a Perfect Preload system, the hubs will stay smoother for longer and require less maintenance, and the geometry of the hub improves lateral and torsional wheel stiffness. As always, no tools are needed for disassembly keeping the time in the repair stand to a minimum.
