Disc brakes are beginning to appear on the most aerodynamic bikes in the world and the SES 7.8 is ready. While most wheel manufacturers simply repurpose their rim brake optimized wheel models into disc brake wheels by covering brake tracks with decals and adding disc hubs and more spokes, this leaves substantial amounts of performance on the table. Removing the constraints of a braking surface on the rim allow us to completely rethink the shape of the rim and more specifically the brake track area itself. The SES 7.8 Disc features patented SES rim curvature that has been optimized for disc brakes. Additionally, the SES 7.8 Disc carbon fiber clinchers and tubulars are much lighter because the material used for heat management has been eliminated. With no braking surface, the rim can be made more aerodynamically efficient and impact resistant. Finally, the SES 7.8 carbon clincher is tubeless compatible and can also be run with standard inner tubes and tires. Like all of the current generation SES carbon clinchers and tubulars, the SES 7.8 Disc has been aerodynamically optimized around fast rolling 25mm tires.
