NEW 80 MM BORA ULTRA AND NEW DARK LABELCOLOURS FOR THE HIGH-PROFILE CARBON WHEELS

In 2012 Campagnolo is even more focused on aerodynamics and time trial races. After the preview of the TimeTrial/Triathlon components, Campagnolo reveals the new Bora Ultra80, which enriches and completes the product dedicated to speed enthusiasts.

The new Bora Ultras with an 80mm rim for tubular tires have been designed and tested in our wind tunnel with the aim of making the aerodynamic and stead as possible, so that they would be responsive during sudden pace changes and balanced at quicker paces.

The new Bora Ultra80 wheels have a carbon hub and an oversize aluminium flange. Like their 50mm equivalents, they are fitted with the special ball/bearings system with CULT technology, the combination of the best ceramic balls and the special Cronitect™ steel cup/cone. The CULT allows the wheel to be 9 times smoother compared to the traditional steel ball/bearings system. The balls and bearings are only lubrificated with oil instead of grease. The treatment used for the bearings prevents oxidation and maintains performance overtime.

The new Bora Ultra80 are also fitted with a dynamic balancing system in the rim: thanks to a special solution applied at the time of manufacturing, the surface of the carbon fiber is positioned in order to achieve a perfect balancing of the rim even at high speed.

The design of the spokes has been created with great care to the smallest detail to make the wheel responsive and steady: the front wheel has 16 stainless steel aero-radial spokes with a variable section and the rear wheel is fitted with 21 stainless steel aero-radial spokes with a variable section and doubled on the cassette side. They are both fitted with an anti rotation system for the spokes that always keeps the rim in an optimal position.

At just 1540gr.(715+825) the overall weight of thet wheels is a record.

 The new Bora Ultra80 have been designed, both from a technical and graphical point of view, to be integrated with the other 50mm wheels of the Bora range. Bycombining the 50mm wheel for the front and the 80mm wheel for the rear, produces an amazing weight of just 1390gr.

The 2012 range also brings some new solutions in terms of design and graphics. For those who like “toneontone” combinations, Campagnolo has decided to introduce a new colour called Dark Label, which will be available for Bora Ultra80, Bora UltraTwo50 and Bora One.
