Campagnolo introduces the first aerodynamic Disc Brake wheel with a 33 mm profile. Each component of this wheel has been optimized in the wind tunnel in order to improve its aerodynamic performance. It therefore delivers multiple benefits that can be noted on different routes, from the most demanding of sprints to relaunching after a bend, while still ensuring efficiency on the flat and now also suitable for the hardest uphill finishes! It is a turning point in the all-rounder segment: a truly multi-purpose wheel. The wheel features carbon rims with a unidirectional aerodynamic finish, new aerodynamic aluminium hubs, and the ceramic USB cup-and-cone bearing system: every design choice has been made with a view to optimising performance. The profile of the rim, which has an internal diameter of 19 mm, corresponds perfectly with 23 mm, 25 mm and 28 mm tyres. In addition, with the 2-Way Fit version, Campagnolo offers its tried-and-tested technology with full compatibility with clincher and tubeless tyres. While the key purpose of these wheels is to deliver extreme performance, safety is also guaranteed thanks to the G3 spoking system with double spokes on the left of the front wheel, to ensure balanced and safe braking in all conditions.

The Campagnolo Bora WTO 60's are a carbon wheelset, designed and optimised in the wind tunnel for road racing over flat terrain. While the aero 60mm deep rim helps these wheels slice through the air in optimum wind conditions, the structure of the rim itself enhances wind power at yaw angles between 12° and 19°, so even in crosswinds, the athlete is driven further and faster. Despite these aerodynamic advantages, the Campagnolo Bora WTO 60's weigh less than 1550 grams per pair - so they're certainly no slouch on the climbs. Campagnolo has designed this 26.5mm wide, tubeless-ready rim to accept larger tyres which minimise rolling resistance, as well as maximise puncture protection, grip and comfort out on the road. Although carbon wheels typically don't have the best reputation for wet weather braking, by applying the AC3 (All Conditions Carbon Control) technology to the braking track of this wheelset, Campagnolo has improved braking in wet conditions by 40%. These advanced carbon rims, are paired with a set of equally advanced hubs. While the monolithic alloy hub shell is designed for minimal drag, the ceramic USB cup-and-cone bearing system ensures a lasting smooth spin and maximised rider efficiency. These hubs are laced to the rims by hand via 18 steel spokes on the front, and 21 on the rear using a cross-sectional spoke pattern which increases wheel strength, durability and power transfer.

The Bora WTO 45 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 Bora 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 45 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. 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 Bora WTO 45 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 Bora WTO 45 join the Bora WTO 60 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 Bora 45 WTO incorporates the carbon fibre 2-Way Fit 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 45mm 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 45 enters into a very competitive segment in terms of weight. Despite the fact that at 45mm it is set against competing wheels based on weight alone, or on weight and minimal aero efficiency…the 45 tips the scales at a scant 1.496 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 45 incorporates the same AC3 braking surface as found on the WTO 77 and WTO 60 wheels. The AC3 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 BORA 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 Bora WTO 45 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. Features: The most aerodynamic The 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 result in a far superior rolling resistance of the cross sections compared to competitor wheels. The smoothest The 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 tubeless tyre 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 Campagnolo Campagnolo's rideability remains high despite the focus on aerodynamics.
