The Bora Ultra 35 meets the requirements of champions using Campagnolo, accompanying them on all their successes, from the Tour 2013 onwards. The clincher and tubular versions of the 35mm wheel, maintain the versatility that brings results on any terrain and in any weather, also adding the advantages of the new generation. 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 medium profile 35mm 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 11x or 9/10x with spacers Weight: 1360g for Clincher, (CA) for Campagnolo, (SH) for Shimano Assembly: The Bora Ultra 35 Wheel is entirely hand built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools.

Campagnolo Bora Ultra 50 Clincher WheelsetCampagnolo Bora Ultra wheels are the choice of pros as they are the perfect wheel for competition. They offer you the performance characteristics that all racing cyclists are looking for - maximum aerodynamics, extreme lightness, lightning quick reactivity and incredible smoothness.Improved Braking in All ConditionsFor the Bora Ultra 50 Clincher wheelset, Campagnolo engineers developed an all-new construction, which has created a braking performance that far outperforms anything found on current carbon rims. The Campy Tech Lab’s developments focused on providing the rider with the same braking performance when riding in the wet as when riding in the dry. The result of these developments is Campagnolo’s most advanced braking surface technology ever. They call it AC3 (All Conditions Carbon Control).Increased Rim WidthCampagnolo has increased the rim width from 20.5mm to 24.2mm - this has not only improved the aerodynamics but allowed the wheel to accommodate wider tyres. Wider tyres increase control, improve grip and make for a more comfortable ride. A wider rim also increases structural integrity without any weight increase to the wheelset.Reduced WeightThe weight of the wheelset is also further reduced, thanks to the front hub having a smaller profile. Even though Campagnolo’s engineers managed to reduce the weight and size of the hub, they were able to save the same high-performance characteristics that the Bora Ultra wheels are renowned for.Features: Full Carbon high profile 50mm clincher rim Includes brake pads specifically for carbon wheels AC3 treatment on the brake surface, improving braking in all conditions RDB (Rim Dynamic Balance) exclusive technology moulded inside the rims, assures perfect balancing of the rims 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 oversize flange with cup and cone CULT bearings, Aluminium axle Aerodynamic spokes with exclusive Mega-G3 spoke pattern and anti-rotation system Quick release with eccentric-closure system Weight: 1435g Technologies: AC3: Under dry conditions the new technology increases braking performance 3% over the previous Bora while increasing the gap with its closest competitor by over 6%. However, when the conditions are insidious and rain has the competition worried, AC3 allows the Bora to excel. While the previous edition of the Bora offered results far beyond those found on competitors' wheels, the AC3 technology increases braking performance an astounding 43% over past Campagnolo models. The powerful braking of AC3 represents a nearly 55% performance gap over that of its closest competitor making for a rather significant advantage when the heat of the race is on.

Being a leading example of advanced Italian road bike technology – the Campagnolo Bora Ultra 50's are the wheelset of choice for World Champions and Grand Tour winners when faced with rolling roads and flat terrain. In this clincher-compatible iteration, they also offer an exceptional level of serviceability too. As a result of the 50mm deep rim, this wheelset maximises aerodynamic gain and rider efficiency on flat roads. However, despite the enormous aerodynamic gains on offer, the Campagnolo Bora Ultra's are somewhat uncharacteristically lightweight compared with other aero wheelsets. Weighing just 1435 grams per pair, these wheels help you dance up climbs with almost as much ease as they help you motor over the flat. Due to the new slightly larger, 24.2mm outer rim width, this wheelset also accommodates much wider tyres than the previous model - drastically improving rider comfort as well as control and grip out on the road. While carbon rims have historically had a reputation for poor braking, with the development of AC3 (All Conditions Carbon Control) technology, Campagnolo has broken the mould. By applying this technology to the braking track, the Campagnolo Bora Ultra's offer a 40% improvement in braking performance in the wet, and 20% better braking performance in drier conditions. At the centre of these wheels are a set of oversized, high flanged carbon-fibre hubs. These are filled with Campagnolo's proprietary CULT ceramic bearings, designed to help the wheels spin smoother, for longer. These hubs are laced and balanced to the carbon rim, by hand using Campagnolo's distinctive G3 spoke pattern via 18 bladed stainless-steel spokes in the front, and 21 in the rear. These design and manufacturing techniques create an aero wheelset that is incredibly torsionally stiff and efficient, ensuring maximum speed and lasting race-winning performance.
