With 2-Way Fit, Campagnolo customers will be able to personally test which of the two solutions suits them best or use the clincher for training and the tubeless tyre for the day of the race. With no doubt, tubeless tyres are the future of road cycling. Apart from greater comfort, the advantages are many: using a tubeless tyre you can exploit the greater smoothness due to the absence of friction between the tyre and the tube. There are no risks of sudden deflation when a tubeless tyre is punctured, a great advantage in safety terms. The lack of tubes eliminates puncture risks. And what if the tubeless tyre has a puncture? The Campagnolo 2-Way Fit system allows you to use a traditional inner tube by simply removing the hermetic closure valve to ride home with no problem. CULT Bearings: Ceramic Ultimate Level Technology (CULT) is the combination of the highest quality ceramic ball bearings and stainless-steel races available on the market, in other words, the technological excellence that makes Campagnolo brand products stand out. Ceramic ball bearings make it possible to reduce friction to the minimum and maintain consistent performance over time. Bearing races in stainless steel, with thermochemical surface treatment, make the sliding surface of the bearings on which the ceramic balls rotate, extremely hard and resistant to wear. This Campagnolo solution, covered by specific patents, reduces wheel and crankset friction to a minimum, thanks to two characteristics that only CULT technology offers: the lubrication system, just a film of oil instead of the usual grease, and a structure that is totally impervious to dirt, so much so that Campagnolo components using CULT technology have no need for dust protectors. The result? The smoothest, longest-lasting ball bearings on the market! Try them! G3 Pattern: Campagnolo has developed an assembly architecture that, 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 two sides of the wheel, there are no more wheel vibrations, even for heavier people.Manufacturer's Part Numbers: CPW5220DA Brown Dark Copper Shaded 700c Shimano/SRAM CPW5220D Brown Dark Copper Shaded 700c Campagnolo CPW5220DB Brown Dark Copper Shaded 700c SRAM XD Sram XDRBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

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.
