The Smart ENVE System 2.2 is the ultimate climbing wheel with aerodynamic properties that refine stability in the most extreme wind and weather conditions. As such, lightweight trumps drag reduction with the SES 2.2. The SES 2.2 underwent in-frame development in the Mercedes GP-Petronas wind tunnel in order to define the final shape of the rim. Unlike the other SES wheel sets, the SES 2.2 features the same rim geometry front to rear whereas its SES counterparts have dissimilar rim width and depth front to rear in order to maximize aerodynamic efficiency. In terms of tire fitment, the SES 2.2 is developed to be used with 25mm tires and the clincher version of the rims is tubeless compatible. Because the SES 2.2 is designed to be ridden through the mountains, it was important up the performance levels of our molded brake track texture technology. As such, the SES 2.2 is the first SES rim to feature our new molded in brake track texture. This new brake track texture improves braking performance by as much as 30% over the previous brake track and performs as well in wet conditions as it does in dry. Each SES 2.2 wheel set includes 2 pair of our new black brake pads which have been specially formulated to improve braking power, modulation, and wet weather performance. The combination of the new brake track and black brake pad compound deliver the ultimate in rim brake technology. The SES 2.2 debuted in the pro peloton at the 2015 Tour de France under Team Dimension Data (formerly Team MTN-Qhubeka).
