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.

The Campagnolo Bora Ultra 50 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 50 Wheelset is the increased rim width, moving from 20.5 to 24.2 mm. This allows the Bora Ultra 50 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. If you're looking for the complete pro package but don't have the support car to ride tubular, the Campagnolo Bora Ultra 50 Clincher Wheelset has all the benefits you need to perform at your best.
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).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, thus improving grip and creating a more comfortable ride.The wider rim profile increases structural integrity, without increasing the weight of the wheelset.FEATURES AND BENEFITSFull 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 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: 1215g for Tubular,Weight: 1435g for Clincher.

The Bora WTO 33 stands out amongst the current line-up for its extreme versatility. While certainly not the only element in an efficient wheel, the rim is certainly the largest component in the build and as a result the recipient of a great deal of attention in terms of development. The Campagnolo carbon fibre BoraTM WTO rims represent the maximum in terms of not only aerodynamic profile design but versatile aerodynamic design. If a wheel is to provide greater aero efficiency it must do so in real world conditions which present many variables and very few constants. Mother Nature does not create wind in a uniform manner or from the same direction. At the same time, racecourses aren’t typically straight nor do riders maintain a perfect position as if in the wind tunnel atop a trainer. With that in mind, Campagnolo engineers set about to account for all of these variables in what has come to represent perhaps the most comprehensive aerodynamic study ever performed by the company to produce wheels that are WIND TUNNEL OPTIMIZED for real world conditions.The Bora WTO 33 carbon fibre rim takes a versatile aerodynamic design and adds an even more versatile rim depth making for a wheelset that is even better poised to take on varied terrain, courses and conditions. The lower profile is even more adept at slipping through side winds and confers an even higher degree of handling when averse and variable wind conditions are at play. The BoraTM WTO rim shape at 77,60 and 45mm are efficient to the point that it not only reduces drag, but at certain angles is capable of reducing it to the point of negative drag, almost pushing the wheel forward. The 33mm rim depth on the other hand confers a similar performance advantage while doing so in a more versatile and lighter weight package.While most aero projects concentrate solely on the rim, the WTO project took a comprehensive look at the entire wheel, ensuring that all components in its build confer aerodynamic efficiencies to the complete unit. To complement the new standard in aero rims both the hub and the spokes were redesigned to ensure a complete aero unit. The BoraTM WTO 33 incorporates the same aero hubs and spokes first seen on the WTO 77 and 60mm wheels. The hubs are constructed from aluminium and follow the same design premise of the rim in that it must be aerodynamically efficient in a versatile manner. Slimmer towards the centre and growing in width towards the flanges where it connects with new 3D aero profile spokes.The efficient wheel is appreciated when out on the road, and as such must be tested, developed and conceived considering the tire with which it is built. The research into making a more efficient rim already called for a wider stance in general but the 19mm inner width provided the multiple benefit of a better performing rim design, better fit with the larger tire sizes (25 and 28mm while compatible also with 23mm) and an overall more efficient complete unit (tire + rim). The wider stance allows the tire to take on a more aerodynamic shape and as such, allows for the tire to become efficient in terms of drag as well. The 19mm inner width is uniform across all wheels of the WTO family.While boosting aero efficiency is paramount, reducing rolling resistance pays significant dividends as well. One simple way to improve rolling efficiency is to add extremely efficient bearings. The BoraTM WTO 33 join the BoraTM WTO family as they roll smoothly atop USB ceramic bearings.Rolling resistance is created inside the hub but the friction between the tire and the road must be overcome to create forward movement as well. Rolling resistance varies depending on the type of tire being used and as such the WTO wheel family is constructed in a way to allow the use of the two most efficient tire solutions possible. The BoraTM 33 WTO incorporates the carbon fibre 2-Way FitTM profile in order to offer the possibility to choose between tubeless and clincher tires, with no need for additional material or conversions. The new, complete range of WTO represents not only the most efficient wheels possible in terms of aerodynamic performance and low rolling resistance but by do so while maintaining an additional focus on weight, making for an ever more efficient total structure. Lighter wheels make for faster changes in speed that require less energy to move as a result of lower rotational mass. Campagnolo carbon expertise allows for the 77mm and 60mm rim to perform its task at a lower weight than comparable rim heights from competitors. The 33mm are no different, on par or lighter than the lightest wheels of similar rim depth. The hubs, made from aerospace grade alloys and engineered to reduce every unnecessary milligram from their construction also contribute to the scant weight of the overall wheel. Whereas the 77 and 60 represent true featherweights when compared against even the lightest wheels at their rim depth, the 33 enters into a very competitive segment in terms of weight. Despite the fact that at 33mm it is set against competing wheels based on weight alone, or on weight and minimal aero efficiency…the 33 tips the scales at a scant 1388 grams.Reducing the weight to a minimum is a feat in and of itself but doing so while maintaining Campagnolo strict standards in terms of safety and reliability makes these wheels engineering examples worthy of every accolade they receive. Safety and reliability however does not only come from sound construction but also via a heightened degree of control with which to harness the speed of the fastest wheels on the road. The rim of the WTO 33 incorporates the same AC3 braking surface as found on the deeper WTO wheels. The AC3TM technology confers a “best in class” braking performance and its extreme control in all conditions makes it an imperative addition to all Campagnolo carbon fibre racing wheels. The Bora name is prestigious and with a long and extremely successful past and present, it has earned its good name repeatedly. The WTO project has proven itself worthy of being associated with this long pedigree of reliable performance solutions by setting yet another standard for the cycling industry. The BoraTM WTO family proudly joins the elite club of Bora wheels and Campagnolo is extremely pleased to announce that this prestigious family is growing. With the BoraTM WTO 33 there is now an extremely efficient carbon fibre racing wheel solution for all preferences. The new standard is here and now in numbers. Its name is BORA WTO.The most aerodynamicThe rim design enables the maximum amount of aerodynamic penetration when the wind angle is between 12° and 19°, making it a thrust for triathlon athletes. The streamlined design of the central part of the hub decreases the frontal area of the component whilst the special design of the flanges favours airflow detachment. The 18-spoke elliptical cross section in the front and 21-spoke rear cross section in the rear result in a far superior rolling resistance of the cross sections compared to competitor wheels.The smoothestThe well-known USB cup-and-cone bearing system guarantees smoothness in the ceramic bearings. The 2-Way Fit profile allows you to mount either a clincher tyre or a tubular tyre, with less rolling resistance: the Tubeless. The C19 class allows you to mount tyres from 23, 25 to 28 mm, with perfect pairing of the rim-tyre system.Choose aero... but make it CampagnoloCampagnolo's readability remains high despite the focus on aerodynamics.
