CAMPAGNOLO BORA WTO 33 DB 2WF DARK 前+後 USB 軸承 碟剎輪組

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-knownUSB cup-and-cone bearing systemguarantees smoothness in the ceramic bearings. The2-Way Fitprofile 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 tehAll 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.

Further technical details

Full Carbon C19 rims- Great comfort and maximum aerodynamics for interacting with new tire standards. Extremely high lateral wheel stiffness and reactivity.

Aluminum hubsprovide lateral stiffness and reduced weight.

Oversized flangesfor greater torsional stiffness and greater reactivity.

Aluminum axlesreduce the wheel's weight.

Cup and cone bearings- Easy ball/bearing adjustment, reduces possible ball/bearing play, precision operation, maintains performance over time

Spokes with aerodynamic profileprovide the maximum aerodynamic penetration and reduce aerodynamic drag, saving the rider's energy.

Spokes anti-rotation systemprevents twisting, keeps the spokes in the aerodynamic position.

Aerodynamic quick releases(included)
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.

Brake pads made especially for carbon wheels(included)
The optimized brake pad compound increases the brake performance by about 40% on wet surfaces and 20% on dry surfaces without increasing the wear and tear on the pad. For a more modular and more secure stop.


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.
