Disc brake technology offers improved braking performance for amateur and professional road cyclists alike. Carbon fiber braking surfaces are a major design constraint that limits weight savings and rim design. By removing the constraints of a braking surface, we can completely rethink the shape of the rim. The SES 5.6 Disc features patented SES rim curvature but has been further optimized for disc brakes. Additionally, the SES 5.6 Disc carbon fiber clinchers and tubulars are very lightweight because the material used for heat management can been eliminated. This allows for a more structurally efficient and impact resistant rim. Finally, the SES 5.6 Disc carbon clincher is road tubeless compatible and can still be run with standard inner tubes and tires. Like the current generation SES carbon clinchers and tubulars, the 5.6 Disc has been aerodynamically optimized around 25mm tires.
