ENVE
SES 7.8 Clincher Disc Brake Wheel Rim - 700c/Front/24 Hole

The ENVE SES 7.8 Disc rims are ready to be built into ENVE's fastest disc-specific aero wheelset, giving triathletes, time triallists and road racers maximum aerodynamic performance and crosswind stability.

Designed by aerodynamicist Simon Smart and utilising in-frame aero development at the Mercedes-AMG Petronas wind tunnel, the SES 7.8 Disc brings together dissimilar front and rear rim depths, widths and sidewall curvatures. This combination optimises the aero efficiency of the wheels and bike as a whole, giving blistering real-world speed and outstanding crosswind stability.

Like all ENVE SES wheels, the SES 7.8 Disc gets its name from its rim depths to 71mm front and 78mm rear. The wider front rim shape features the best compromise between steering stability and drag reduction when taking into account the relatively clean oncoming flow of air. The rear sees a more turbulent flow and larger frame interaction, negating stability concerns and allowing for a narrower wheel that improves overall airflow attachment for reduced drag.

For the SES 7.8 Disc, ENVE has removed the constraints and weight of a traditional brake track on the rim, opening up a realm of aerodynamic and structural possibilities. This has allowed ENVE to use a completely different rim construction, laminate and curvature for a lighter, more aerodynamic wheel compared to the rim-brake SES 7.8 to without sacrificing stiffness or strength.

The rim's clincher design utilises advances in road tyre and frame technologies to add user-friendly tubeless compatibility optimised for 25mm tyres. This gives real-world gains in rolling resistance, comfort, traction and reduced chances of pinch punctures.

Industry leaders in carbon fibre, every ENVE rim is handmade from raw uni-directional carbon at ENVE's headquarters in Utah, USA. The bespoke construction process utilises rim-specific carbon laminates, moulded spoke holes, removable bladders, and a gorgeous paint-free finish to reduce weight while maintaining strength, stiffness and allowing the beautiful handmade quality to shine through.
