Campagnolo Bora WTO 33 Disc Brake wheelset

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.

33 MM but aero
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 the shut-off of the flow of air, thus reducing turbulence. The 24-spoke elliptical cross section results in a far superior rolling resistance.

Fast and fluid
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 tyre which offers the least rolling resistance possible: the tubeless tyre. The 19 mm inner diameter enables you to mount 23, 25 and 28 mm tyres, with perfect pairing of the rim-tyre system.

The choice of campagnolo
Campagnolo's rideability is enhanced by the 33 mm profile, despite the aerodynamic design of the rim. The wheel structure enables reducing energy dissipation, transferring all the energy produced by the cyclist to the asphalt. A 33 mm profile and a weight of 1,485 g for the pair makes this wheel ideal for even the most demanding routes.

Technologies

2-way fit™
Thanks to 2-Way Fit™ technology, if you choose Campagnolo® wheels you can test them out to see which of the two solutions feels better for you, or use clinchers for training and tubeless for racing. Tubeless are without doubt the future of tires for road cycling. Apart from greater comfort, other big advantages include the fact that tubeless tires let you make the most of the greater smoothness due to the absence of friction between tire and inner tube. Plus, a tubeless will not suddenly deflate when punctured, which is definitely a good thing in terms of safety. And finally, tubeless tires do away with any risk of pinch flats, because there is no inner tube. If you get a puncture with a tubeless tire, the Campagnolo® 2-Way Fit™ system lets you simply remove the airtight valve, fit a classic inner tube and continue to pedal: problem solved.

Dynamic balance™
RIM Dynamic Balance™ – aluminum wheels The concept is as simple as it is genius: balancing the weight of the rim joint with a mass of identical weight on the opposite side of the rim. For top-end models this is achieved by intervening on the section of the rim opposite the joint. SPOKES Dynamic Balance™ For entry-level models, the balance is achieved with two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics. RIM Dynamic Balance™ – Carbon wheels For carbon wheels, the principle is the same but the technology differs. The pieces of carbon cloth are aligned using a special procedure that ensures the rim is always balanced.

G3 spoke geometry
Campagnolo’s iconic G3 geometry challenges the conventional configuration of wheel spokes on racing bikes. Groups of three parallel straight-pull spokes are in fact arranged in a ratio of 2:1. Having twice as many spokes on one side allows wheels with G3 technology to achieve perfectly balanced tensions, increasing stiffness and improving energy transfer. An iconic design with unique style that helps to improve load absorption and reduce weights. The G3 spoke pattern also has a positive effect on the steering experience: the original triplet pattern reduces perceived vibrations, minimizing micro-deformation of the rim under tension and its response to stressors on the course. G3 geometry is designed with optimized solutions for front and back wheels. The front one has more spokes on the disc side to absorb braking loads. Whereas on the back one the same loads are transferred to twice the number of spokes on the cassette side through the monolithic hub body: an intuitive idea that enables functioning during both braking and energy transfer during pedaling. The G3 spoke pattern is used on Bora WTO and Bora Ultra WTO racing wheels, wheels in the Shamal family and on all the aluminum wheels in the Campagnolo collection.

Momag™
WHAT IS THE MOMAG™? An absolute genius of a magnet. It is the tried and tested, patented “Mounting Magnet” system: MoMag™ for short. HOW DOES IT WORK? The nipples, once inserted inside the rim via the valve hole, are “guided” to the point of connection with the spoke by means of a magnet. This simple but ingenious system makes it possible to have a wheel without holes on the upper bridge, but with spokes tensioned by traditional nipples. ADVANTAGES No holes on the rim means that the rim is uniform at every point, free from stress points or zones of structural weakness. It offers a further advantage in terms of lightness for clincher profiles as no rim tape is required. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension and greater stiffness, which, in terms of performance, mean better reactivity and ease of handling. But that’s not all. The advantages also include extremely quick simple spoke maintenance or replacement. MOMAG™ technology is used on Bora WTO carbon wheels for racing bikes and on Shamal Carbon, Levante and Hyperon Ultra wheels.
