Campagnolo Bora WTO 60 Set di ruote 28" 100/130mm HG 9-11 velocità Dark Label Clincher TL

With the new Bora WTO 60, Campagnolo has focused on producing the most efficient wheels possible in terms of decreasing rolling resistance as the cyclist moves and maximising aerodynamic efficiency. The acronym WTO - WIND TUNNEL OPTIMIZED – calls to mind the environment that the team of Campy Tech Lab engineers worked in to meet these challenging project objectives. The new Bora WTO 60 wheels feature exclusive design characteristics that establish new standards in aerodynamic efficiency. Directly from the wind tunnel to the market, the pair of Bora WTO 60 wheels is destined to become the necessary choice every time a cyclist faces a route that requires average speeds of more than 40 km/h.

The most aerodynamic
The rim design enables the maximum amount of aerodynamic penetration when the wind angle is between 12° and 19°, making it a thrust for triathlon athletes. The streamlined design of the central part of the hub decreases the frontal area of the component whilst the special design of the flanges favours airflow detachment. The 18-spoke elliptical cross section in the front and 21-spoke rear cross section in the rear result in a far superior rolling resistance of the cross sections compared to competitor wheels.

The smoothest
The well-known USB cup-and-cone bearing system guarantees smoothness in the ceramic bearings. The 2-Way Fit profile allows you to mount either a clincher tyre or a tyre which offers the least rolling resistance possible: the tubeless tyre. The C19 class allows you to mount tyres from 23, 25 to 28 mm, with perfect pairing of the rim-tyre system.

Choose aero... but make it Campagnolo
Campagnolo's rideability remains high despite the focus on aerodynamics. The wheel structure enables reducing energy dissipation, transferring all the energy produced by the cyclist to the asphalt. A 60 mm profile and a weight of 1,547 g for the pair makes this wheel ideal for riding on routes that enable going more than 40 km/h.

USB Ultra Smooth Bearings
Perfectly smooth surfaces and lower friction to reduce loss of power are the most interesting features. Add on the reduced weight and resistance to corrosion and you will understand why we can give you the best thanks to USB. All your power will be transferred onto the road. Campagnolo has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability.
In fact, all the projects are entirely developed in our R&D department Campy Tech Lab and we have put obsessive care into taking care of every detail. The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings. Now improving your performance during the race or simply going for a ride with your friends will be easier. USB - Ultra Smooth Bearings - technology is used for Record cranksets and for the new Shamal Ultra wheels.

G3 Geometry
Campagnolo’s unique G3 spoke pattern comprises groups of three parallel straight-pull spokes, arranged in a 2:1 ratio. Having twice as many spokes on one side allows wheels with G3 to counteract the asymmetric drivetrain and braking forces acting on them, creating more symmetric performance and equalising the load. Energy transfer and lateral rigidity are improved, and spoke tension is optimised, reducing stress and increasing lifespan. All Campagnolo disc brake wheels utilise the G3 pattern, the front wheel has more spokes on the disc brake side, and the rear is biased to the drivetrain side.

AC3
It is a general consensus of opinion within the cycling world is that one of the major drawbacks of the carbon fi bre racing rim is the reduced rim braking performance in the wet. To combat this problem Campagnolo has developed the All Conditions Carbon Control, or AC3 Technology. The introduction of the meticulously researched textured design of the rim brake area creates a surefooted stopping power that is reliable and potent no matter what the weather will throw at you. On the Campagnolo Bora rim brake wheelset range, under dry conditions, the new technology increases braking performance by 3% compared to the previous Bora while increasing the distance from its closest competitor by over 6%. However, it is when the weather conditions deteriorate that the AC3 technology permits the Bora to excel increasing braking performance an astonishing 43% over previous Campagnolo models. The powerful braking of AC3 represents a nearly 55% performance gap over that of its closest competitor making for a signifi cant advantage when the heat of the race is on.
