For most of us, riding a bike is all about speed, because we know how much fun it is to fly down the road. The majority of our ability to build speed comes from our own strength, but having some speedy equipment makes all the difference, too. Enve knows the importance of a fast wheel, bringing us the new SES 6. 7 Disc Brake Wheelset. Constructed with carbon rims, the SES 6. 7 focuses on aerodynamics with a 60mm front wheel and a 67mm rear wheel. Creating the wheelset with a different front and rear depth is based on how each wheel is differently affected by the wind, allowing for a wheel combination that is as efficient and aero as possible. The SES 6. 7 is designed for the use of only tubeless tires, allowing you to really feel your wheels underneath you for more control that results in a faster, smoother, and more efficient ride.
