Your departure from T1 won't be complete until you add the whoosh of a rear disc wheel to your setup. A few years back, an option like the PRO Disc Rear Wheel in a clincher version wouldn't have stood much of a chance against more reliable tubular models, but with improvements being made to clincher designs, you can now round out an enviable TT bike with the reassurance that your wheel/tire setup will stand up to long bike legs without a flat tire spelling the end of your race.
PRO specs the Clincher Disc Wheel with its parent company Shimano's Ultegra hub, which is compatible with 10- and 11-speed drivetrains. The rim is shaped from carbon fiber in a 2x2, 3K twill weave using a sandwich construction that features lightweight foam at its center. This construction results in an improved strength-to-weight ratio and a shape that's ideal for non-drafting events where every bit of drag reduction becomes crucial. The wheel's alloy brake track maintains better braking, reducing the risk that you'll barrel into slow dismounters as you approach T2.
