The Campagnolo Bora Ultra WTO 60 DB road bike wheels for disc brakes are the fastest wheels in the Campagnolo range. The Campagnolo Bora Ultra WTO 60 DB wheels feature a 60mm high aerodynamic rim of 26 mm externally and 19 mm internally. This makes the Campagnolo Bora Ultra WTO 60 wheels best suited to 25 mm tyres for the best performance. But it is also possible to go wider with 28 mm tyres for more comfort and a slightly lower tyre pressure of 5-6 bar (70-90 psi), depending on rider weight. The 60mm high rim depth also makes these wheels ideal for use in triathlons or time trials. The Bora Ultra WTO wheels have received a substantial bearing upgrade over the Campagnolo Bora WTO wheels. The bearings feature CULT technology, which means they are ceramic cup-and-cone bearings. This makes the bearings run extremely smoothly and wear less quickly. Thanks to the 2-way fit system, you can ride tubeless as well as with folding tyres and inner tubes.
