The family of carbon aero wheels is further enhanced with the Bora WTO featuring a 45 mm profile, designed to appeal to a broader customer base. The design of the rim enables maximum aerodynamic penetration, and at certain angles, the wind can actually become a valuable ally to the rider. Aerodynamic aluminium rims and hubs and ceramic USB cup-and-cone bearing system in the hubs themselves: every design choice has been made with a view to optimizing performance.
The 19 mm internal diameter of the rims enables tires of 23mm, 25mm and 28mm to be fitted. In addition, with the 2-Way Fit (Tubeless Ready) version, Campagnolo offers its tried-and-tested technology with full compatibility with clincher and tubeless tires. Furthermore the Bora WTO 45 wheelset offers water transfer graphics, radial spoke lacing on the front wheel and G3™ on the rear. External, self-locking nipples, hubs in aluminum with differentiated front and rear diameters, adjustable ceramic USB™ bearings, aluminium freewheel body and aerodynamic quick releases are just some of the top features of the Bora WTO 45.
45 mm deep rim profile but aero
The rim design enables a high 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 favors 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 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 tire or a tubeless tire, with less rolling resistance. The C19 class allows you to mount tires from 23, 25 to 28 mm, with perfect pairing of the rim-tire system.
This construction relies on AC3™ technology to create surefooted stopping power that is reliable and potent no
matter the weather conditions. All Conditions Carbon Control™, or AC3™, was developed not only to generally improve an already great braking performance but also to address one of the principle drawbacks to the carbon fiber racing rim: braking performance in the wet. Aside from the externally obvious textured design upon the brake track, the construction of the new Bora™ wheels underwent some internal optimization to orient the fibers in a way to guarantee maximum integrity in the face of new input deriving from a new braking surface. The highly sophisticated resin optimized by Campagnolo engineering staff to withstand higher temperatures than the Bora™’s competition and to dissipate the extreme heat produced during the braking phase.
full-carbon C19 rim
Great comfort and maximum aerodynamics for interacting with new tire standards. Extremely high lateral wheel stiffness and reactivity.
Exclusive rim printing system
rim painting no longer required. The weight is greatly reduced and the surface is free from imperfections.
Exclusive G3 spoke pattern
perfect balance of the spoke tensions on both sides of the wheel. Reduces stress, increases transversal rigidity and the transmission of power to the wheel. G3 eliminates vibrations even with "heavy" cyclists.

Steel spine and eccentric, lever with drill lightening and aluminum die. The eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.
Campagnolo® has developed an assembly architecture which, 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 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.
The wheel is entirely hand-assembled by a specialized Campagnolo® technician and is checked in every tiny detail with electronic instrumentation.
This ensures maximum performance and reliability for all Campagnolo® wheels.
