"While most will recognize the tubular wheels as the go-to choice for top professional riders, the fact remains that tubular tyres are less practical than clinchers for those of us not fortunate enough to have a support car with spare wheels following behind. Now, thanks to some diligent work by Campagnolo engineers, there will be no more reason to sacrifice performance for tyre security as the Bora wheel family is now available in clincher version in addition to the tubular version seen in the pro-tour.
Bora Ultra is the choice of the pros, the ideal competition wheel. The maximum aerodynamic performance, extreme lightness, and the surprising reactivity combined with incredible smoothness. Bora Ultra Two provides characteristics that every cyclist wants. The secret of this legendary wheel lies in the details that make it truly unique and unrivalled. And the innumerable victories are its best testimony. The Bora Ultra wheel is entirely hand-assembled by a specialised Campagnolo technician and is checked in every tiny detail with electronic instrumentation. This ensures maximum performance and reliability for all Campagnolo wheels.
Perhaps the most noticeable improvement will come in the form of a new, wider profile of the Bora rim. Moving the width from 20,5mm to 24,2mm allowed engineers not only to improve upon aerodynamics but also to house wider tyres. The wider tyres increase control as the contact area between tyre and asphalt is increased, thus improving grip in addition to creating a more comfortable ride. The new wider structure also represents an increase in structural strength, thus rendering the already universally lauded resistance and reliability of the Bora even more adept at handling any course or condition that presents itself on race day. The wider structure aids in aerodynamics, increases structural integrity but also allows engineers to create a lighter version of the famed Bora wheel.
While the contrary might seem more likely, the larger profile of the Bora rim creates a stronger structure with less need for material intended for structural reinforcement. Campagnolo is thus able to give increased structural integrity at a lower weight with regards to the rim.
The graphic application was also studied and a new method was utilized which allows Campagnolo to apply the logos via water transfer thus avoiding heavier adhesives. This too represents a weight savings of nearly 15 grams in addition to a cleaner and more durable aesthetic quality.
Weight is further reduced thanks to a smaller profile front hub applied to this new Bora design. Campagnolo engineers were able to reduce the weight and size of the hub while maintaining all of the performance characteristics of the previous version. In other words, the same fantastic Bora performance in a smaller package.
CULT Ceramic bearings 9 times more efficient that standard bearings, the will spin for up to 47 minutes after being run at 500rpms.
FEATURES AND BENEFITS
