Like all ENVE SES wheels, the Enve SES 7.8 Tubular Rim  gets its name from its rim depths – 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 rim brake rider looking for uncompromised braking performance, there's nothing better than ENVE's full carbon moulded brake track. This textured surface with high temperature resistance achieves exceptional stopping power and equal performance in wet and dry conditions. Braking force at the levers is also decreased by 30% compared to the previous generation brake track, allowing you to brake late with confidence through sweeping bends.   The clincher version of the SES 7.8 also 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.
