Campagnolo Bora WTO 45 Road Bike Wheels

The Campagnolo Bora WTO 45 road bike wheels are light, stiff and aerodynamic. Campagnolo introduced this aerodynamic all-round wheel set with a depth of 45 mm for a wide audience. The Campagnolo Bora WTO wheels are at an extremely interesting price level compared to the Bora One wheels. The Campagnolo Bora WTO 45 wheels have been optimised in the wind tunnel and feel much more stable and aerodynamic than the Campagnolo Bora One wheels.

Thanks to the internal rim width of 19mm and the external rim width of 26.5mm, 25mm tyres fit best on the rim for optimum aerodynamics. In addition, thanks to the AC3 brake rim you get good braking performance under all conditions comparable to aluminium rims.

The design of the rim allows for aerodynamic properties and, at certain degree angles, can even stimulate faster cycling. The wheel features carbon rims with a unidirectional aerodynamic finish, new aerodynamic aluminium hubs and the ceramic USB cup & cone bearing system: every design choice has been made with a view to optimising performance.

Technology

WTO - Wind Tunnel Optimised
Campagnolo Tech lab engineers have completely redesigned the Campagnolo Bora wheels in the wind tunnel. The Campagnolo Bora WTO wheels have emerged from many lab tests and intensive field testing by well-known professionals such as Nairo Quintana and André Greipel. The rim design offers enormous advantages in terms of stability in the wind. The most optimal aerodynamics are achieved in wind directions between 12 and 19 degrees. The rim profile ensures that you need to apply less force at the same speed compared to a non-aerodynamic rim profile. Especially when your speed exceeds 40 km/h, these advantages increase exponentially.

AC3 brake edge
AC3 gives surprisingly good braking performance, especially in poor conditions. Laboratory tests have shown that it enables a 6% improvement in braking power in dry conditions compared to before. On wet surfaces, the difference is astonishing: here, there is an increase of 43%, bringing the braking distance close to that in dry conditions.

USB - Ceramic Ultra Smooth Bearings
Campagnolo has a reputation for reliable, high quality hubs with low rolling resistance. In fact, all development is done in-house with extreme precision. The resistance of hubs with USB (Ultra Smooth Bearings) ceramic bearings is up to 50% lower than regular bearings. Furthermore, ceramic bearings last many times longer than steel bearings.

2-Way Fit
Ceramic bearings are a great alternative to steel bearings, and can also be made tubeless thanks to the 2-way fit rim profile. However, as the name suggests, the 2-Way Fit rim profile is a technology for both clincher and tubeless tyres. Tubeless riding has many advantages such as reduced rolling resistance, increased riding comfort and improved grip. The main advantage of riding tubeless is that you can continue to ride when you have a puncture. The liquid latex fills the hole in the tyre within seconds.

G3 spoke pattern
Although the main purpose of these wheels is to provide extreme performance, safety is also guaranteed thanks to the G3 double spoke system on the left hand side of the front wheel to ensure balanced and safe braking under all conditions.

Compatibility

Delivery includes

• Campagnolo Bora WTO 45 wheels
• Campagnolo tubeless valves
• Campagnolo valve extenders
• Campagnolo quick release skewers

Assembly

• Cassette remover Shimano or Campagnolo
• (possibly a torque wrench)

Installing a cassette on a wheel is easy if you have the right tools. If you purchase a cassette remover with a Shimano fit, you will be able to mount either a Shimano or Sram cassette on your rear wheel. Please note! For a Campagnolo cassette you need the Campagnolo tool. If you have a Shimano 9/10-speed cassette, first slide the spacer over the body. Then you place the cassette on the body. This can only be done in one way because of the fit of the body. Finally you turn the washer straight on by hand and tighten it with the cassette tool. Cassettes aren’t easily overtightened, but if you want you can use a torque wrench for this.

User tips

• Pay attention to the direction of travel when mounting your tyres
• For Shimano 9/10-speed, do not forget to mount the spacer first before installing the cassette
• Make sure the rim tape is stuck well in the rim
• On both the front and rear wheel, there is a small adjustment screw on the left-hand side to adjust the side play
