For speed seekers, riders of rollers, and everyone, really.

When speed across most any terrain is priority number one, look no further than the SES 4.5. Originally designed for the cobbles and crosswinds of Paris-Roubaix to provide an aero benefit with high volume tires, the SES 4.5 was the first of its kind and is now re-designed to deliver more speed in a lighter package.
