Campagnolo Wheelset Bora WTO 33 -2 Rim

The family of carbon aero wheels is further enhanced with the Bora WTO featuring a 33 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 23 to 28 mm to be fitted. In addition, with the 2-Way Fit (Tubeless Ready) concept, Campagnolo offers its tried-and-tested technology for full compatibility with clincher and tubeless tires. Furthermore the Bora WTO 33 wheelset offers water transfer graphics, radial spoke lacing on the front and G3 spoke pattern on the rear wheel. External, self-locking nipples, aluminium hubs with differentiated front and rear diameters, adjustable USB ceramic bearings, a aluminium freewheel body and aerodynamic quick releases are just some of the top features of the Bora WTO 33.

Highlights of the Bora WTO 33 wheels

33 mm deep rim profile but nevertheless aero

The 33 mm high profile and a light weight of just about 1400 grams for the pair of wheels make Campagnolo's WTO 33 the ideal set for mountain tracks without sacrificing aerodynamic advantages on the straights or in the flats. 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.

Smoothest rolling 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 makes the use of tires between 23 and 28 mm possible, with perfect pairing of the rim-tire system. To gain the perfect advantage from the aerodynamic concept, the manufacturer recommends the use of 25 mm wide tires.

Fast in the wind and reliable during deceleration

The construction relies on teh All Conditions Carbon Control (AC3) technology to create surefooted stopping power that is reliable and potent no matter the weather conditions. The AC3 concept was not only developed 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 Bora wheels underwent some internal optimization to orient the fibers in a way to guarantee maximum integrity in the face of input deriving from the revised 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.
