Description of Campagnolo Bora Ultra 80 - 28" Rear Wheel Tubular Tire - Dark
The new Bora Ultra 80 offers a full-carbon rim with 20 mm wide, bearings with CULT technology and carbon hubs. It is improved in terms of lightness, aerodynamics, stiffness and comfort thanks to use of the new wider rim and front and rear hubs with different diameters.
Features & Benefits of Campagnolo Bora Ultra 80
New full-carbon rim 20 mm wide
great comfort and maximum aerodynamics for interacting with new tire standards. Extremely high lateral wheel stiffness and reactivity.
Exclusive rim printing system
rim painting no longer required. The weight is greatly reduced and the surface is free from imperfections.
Exclusive G3 spoke pattern
perfect balance of the spoke tensions on both sides of the wheel. Reduces stress, increases transversal rigidity and the transmission of power to the wheel. G3 eliminates vibrations even with “heavy” cyclists.
RDB™ Rim Dynamic Balance
exclusive system that assures perfect balancing of the rim even at high speeds. Moulded into the rim itself.
New brake pads made espacially for carbon wheelsin scope of delivery
the new blend increases the brake performance by about 40% on wet surfaces and 20% on dry surfaces without increasing the wear and tear on the pad. For a more modular and more secure stop
Spokes with aerodynamic profile
provides the maximum aerodynamic penetration. Reduces aerodynamic drag saving rider energy.
Carbon fibre hub
provides a high degree of lateral stiffness and reduces weight to the minimum.
greater torsional stiffness and greater reactivity.
Cup and cone bearings
easy ball/bearing adjustment, reduces possible ball/bearing play, precision operation, maintains performance over time
the combination of the highest quality ceramic bearings with housing in special Cronitect® steel. Nine times smoother than the standard system. Eliminates oxidation and maintains performance over time.
reduces the weight of the wheel.
new, completely redesigned and lighter aerodynamic-profile wheel block. Steel spine and eccentric, lever with drill lightening and aluminum die. The eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.
Campagnolo® has developed an assembly architecture which, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3™ geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left.
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.
The 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.
