The SES (Smart ENVE System) 4.5 is a road racer’s dream wheelset. The SES 4.5 is lightweight and like all ENVE products is durable enough to be used on a daily basis. The SES 4.5 is an evolution of our patented SES rim shape that reduces drag while at the same time reducing depth. The SES 4.5, like all wheels in the SES line-up, features dissimilar rim geometries front to rear because the front of the bike and the back of the bike interact with the airflow in very different manners. The front wheel is wider and shallower to maximize cross-wind stability and handling. The rear wheel is slightly narrower and deeper to maximize drag reduction off the back end of the bicycle. The SES 4.5 offers more aerodynamic performance than the SES 3.4 at a more manageable depth and weight than the now discontinued SES 6.7. In addition to the gains in aerodynamic efficiencies made with the shape of the SES 4.5, it is also the stiffest wheel in the SES line of wheels. The increase in stiffness as well as aerodynamic performance make the SES 4.5 the perfect wheelset for road and criterium racing where acceleration, and cornering are the name of the game. To further enhance performance out on the road, the SES 4.5 features ENVE’s patented molded spoke hole technology, removable bladders, and molded in brake track textures. Each SES rim features a textured brake track that is molded into the full carbon fiber braking surface. This texture provides for superior modulation, heat management, and wet weather performance. The SES 4.5 is proudly manufactured in the USA.
