As the evidence has become irrefutable that wider tires run at lower pressures offer lower real-world rolling resistance than rock solid skinny tires, its become normal for people to run wider and wider tires even on their racing bikes. The 27mm ENVE SES Tubeless Road Tire for 700c wheels is a prime example of a fantastic option for anyone who wants to get the benefit of a wider tire without having to add too much weight to the equation. The ENVE SES tires have been in development for the better part of a decade and find the tire shape and construction choices can make a huge impact not only on rolling resistance, but also on aerodynamics. Focusing on durability, the designers have turned to Vectran technology which is the most effective high-performance, anti-flat protection available. And since these are designed to be tubeless, the bead has a level of stiffness that will ensure secure sealing between rim and tire. Unless you are racing on the track where there are no potholes or rough sections, the comfort, grip and reduced deflection the 27mm tires provide can transform a ride from drudgery to joy.
