The Campagnolo Bora Ultra 35 Wheelset is the choice of the pros, the ideal competition wheel. Maximum aerodynamic performance, extreme lightness, surprising reactivity and incredible smoothness are all part of the Bora Ultra package.
The Campagnolo Bora Ultra 35 Wheelset features CULT Ceramic bearings, which provide extreme smoothness, the lowest friction coefficient thanks to oil lubrication and are 9 times more efficient than standard bearings and will spin for up to 47 minutes after being run at 500rpms.
Campagnolo engineering staff have developed a new construction that provides a braking performance superior to other carbon rims. The AC3 (All Condition Carbon Control) technology not only improves braking in the dry but boosts performance by 43% over past Campagnolo models and nearly 55% over that of its closest rivals when the roads get wet. Apart from the obvious textured braking surface the construction of the new Bora wheels also underwent internal improvement to ensure maximum integrity when faced with the increased force and heat deriving from the new braking surface.
One of the biggest changes and improvements to the Bora Ultra 35 Wheelset is the increased rim width, moving from 20.5 to 24.2 mm. This allows the Bora Ultra 35 Wheelset to improve its aerodynamic properties and house wider tyres, thus increasing the control and creating a more comfortable ride. The wider rim also contributes to an increase in structural strength, thus increasing the already lauded resistance and reliability of the Bora family.
The wider rim also contributes to an increase in structural strength, thus increasing the already lauded resistance and reliability of the Bora family. The benefits continue, as the wider rim creates a stronger structure with less need for material intended for structural reinforcement decreasing the overall weight of the wheel.
Bearings with CULT technology
The combination between the highest quality ceramic bearings and housing in special Cronitect steel. CULT makes the wheel nine times smoother than the standard system of steel bearings.
The results of G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, reduction of the stress in the rear wheel spokes. And thanks to the G3 system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.
I ride in Japan, which means I do a lot of climbing. I wanted a wheelset that was light enough for steep climbs but also gives an aero advantage for the flats. Since getting these my climbing times and speeds on the flats has improved considerably. The wider rims make for a smooth and stable ride, and the braking feels fantastic.
