bora ultra 50 clincher wheels

Bora Ultra is the choice of the pros, the ideal competition wheel. They provide all the characteristics that every cyclist wants; maximum aerodynamic performance, extreme lightness, surprising reactivity combined with incredible smoothness. The secret of this legendary wheel lies in the details 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. Campagnolo engineering staff have developed a new construction that has created braking performance above and beyond anything found on carbon rims to date. The Campy Tech Lab's developments focused on being able to give the rider the same braking performance in wet conditions as in dry conditions. The result is a new braking surface technology called AC3 (all Conditions Carbon Control). Cult Bearings (Ceramic Ultimate Level Technology) is a combination of the highest quality ceramic ball bearings and stainless steel races available on the market, to reduce friction to the very minimum yet maintain a consistently high level of performance for long periods of time. The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side. Increasing the rim width from 20.5mm to 24.2mm allowed the Campagnolo engineers to not only improve the aerodynamics but also to allow the wheel to accommodate wider tyres. Using wider tyres increases control, as the contact area between tyre and asphalt is increased, improving grip and creating a more comfortable ride. The wider rim profile increases structural integrity, without increasing the weight of the wheelset. **Features:** * Full Carbon high profile 50mm rim, in clincher and tubular versions. * Includes brake pads specifically for carbon wheels * AC3 treatment on the brake surface, improving braking in all conditions * RDB (Rim Dynamic Balance) exclusive technology engineered into the rims, assures perfect balance even at high speeds * Ultra lightweight decals eliminate the need for heavy adhesives and painting, reducing the overall weight by nearly 15g * Carbon hub with oversized flange, cup and cone CULT bearings and aluminium axle * Aerodynamic spokes with exclusive Mega-G3 spoke pattern with anti-rotation system * Quick release with Eccentric-closure system * Freehub: CA 9/10/11/12x, SH 9/10/11/12x * Weight: 1435g for Clincher, (CA) for Campagnolo, (SH) for Shimano **Assembly** The Bora Ultra 50 Wheel is entirely hand built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools.
