![]() The SES line was guided by its holistic approach to performance, its so-called RealWorld Fast design philosophy. Features and technology across the SES line include: This approach evaluates the interaction of the wheels, bike frame, and rider in both the wind tunnel and on the open road. Rim shape and depths take into account the differences in airflow at the front of the bike versus the rear as well as crosswinds. Front wheels are shallower than rear wheels, and feature a more rounded profile to maximize crosswind stability and control.Īs such, all wheels in the SES lineup have a unique shape based on their location on the bike and the airflow. ![]() The rear wheels have a deeper, sharper profile, and were streamlined to maximize power transmission and drag reduction.Īll new SES wheels were aerodynamically optimized around Enve’s 27mm SES hookless tires.Įnve claims that most wind tunnel testing is performed at 48 kph/30 mph. However, only few riders consistently spend much time at or above that speed. The SES™ wheels are therefore designed and tested at both 48 kph/30 mph, and 32 kph/20 mph.Ĭalling it the “pinnacle of modern road wheel and tire system performance,” Enve has been a believer in the road tubeless system since 2016, when it first launched the SES 4.5 AR with a mountain bike inspired hookless bead design. The new SES lineup is tubeless-only and features Enve’s patent-pending Wide Hookless Bead. This technology is Enve’s solution to eliminating pinch-flats, strong enough for road pressures of up to 90 PSI, and compliant with the current ETRTO (European Tire and Rim Technical Organization) tubeless rim with straight-sidewall dimensional standard.Įnve argues that a tubeless setup was never meant to have a hooked bead and rim, stating that the hooked bead was designed purely in order to keep lightweight folding tires from coming off the rim. Enve believes that a hooked bead actually compromises tubeless performance as it makes achieving the critical dimension of the bead seat diameter less precise. Since consumers want tire choices beyond the Enve offerings, Enve has worked with manufacturers across the industry to build a database of tires that are compatible (opens in new tab) with their hookless system as well as recommended tire pressures. “We understand that for the Enve customers it’s a point of much education and discussion,” Pantone said. “But while reading recommendations might be new in cycling it’s certainly not in other industries like cars.”Įnve says that while a customer can still buy the SES rim on its own, it will no longer offer rim builds with any hub other than their own Enve Premium Road Hub. The Enve hub features full premium-grade NTN stainless-steel bearings, a refined lightweight design, flange geometry and a 40t ratchet drive system. Introduced in 2018, ENVE hubs also feature Perfect Preload™, a technology that eliminates the need for bearing preload adjustments over time and ensures longer bearing life with greater efficiency.Įach of the models in the SES collection was designed with a specific rider and application in mind. ![]() From climbing to triathlon to mixed terrain, each model features a scaled per intended application Wide Hookless Bead and inner rim width. So while the ultra-light SES 2.3 features a narrower Wide Hookless Bead with an inner rim width of 21mm, the mixed-surface capable SES 4.5 features a 25mm inner rim width and a substantially larger Wide Hookless Bead. The new 6.7 was Enve’s R&E project and considers it a flagship wheel. It’s made for triathletes as well as aero-loving roadies alike and was optimized to the point of diminishing returns. “There is a point of diminishing returns when it comes to aerodynamics and the weight penalty.
