Bora WTO 33 Disc Brake Wheelset

Whether we race where the road is more often ascending than flat, or where the winds cut across the road at increasingly frustrating angles, we need a lightweight wheelset stiff enough to handle the power when we lay down the hammer. Campagnolo’s Bora WTO series combines carbon fiber rims and USB ceramic hubs for an all-around impressive wheelset to save time and energy as we race for the win. Campagnolo’s Wind Tunnel Optimized (WTO) project sought to redesign not only the rim but also the hub and spokes, to create a truly aerodynamic wheel for real world conditions.


The Bora WTO 33 is the slimmest rim depth of the series, and at a feathery 1455g, these wheels are ideal for the hilliest routes, where lightweight and stiffness are paramount. Campagnolo’s carbon layup design creates their two-way fit, allowing you to run either clincher or tubeless tires on the same rim. The spoke nipples are put into place using a magnet through the rim, which eliminates the need for a drilled hole through the carbon. This creates a uniform rim surface, with fewer weak points, which means a stronger rim that can better handle the power you’re throwing down as you attack up the climb. The smooth surface also eliminates the need for rim tape when set up with clincher tires, saving time and weight. At 19mm internal width, the Bora rims match well with road tires between 23mm and 28mm for an aerodynamic tire profile to further your advantage in the wind. The AFS braking interface works with standard centerlock rotors for secure speed-checking even in inclement weather.


We would be remiss to not draw attention to the hub of the Bora series. Redesigned for aerodynamic advantage, the aluminum externals of the thru-axle hubs allow wind to better flow through the hub, rather than creating drag. The internals of the hub that really excite us: USB ceramic bearings. Ceramic bearings are 50% smoother than standard bearings, which allows them to move past one another more efficiently, saving you energy with each pedal stroke. In addition to efficiency, ceramic bearings are also lighter in weight for less heft to haul through the race course. In the rear, the plasma-treated freehub makes for a lighter-weight, more resilient aluminum that maintains strength and durability.


The Bora 33 WTO Disc Brake version uses G3 lacing in the front and rear. In the rear, G3 lacing places twice the number of spokes on the drive side than the non-drive side of the rear wheel, which helps the power transmission from rider to hub by reducing any twisting that would occur due to pedal stroke. In the front, there are twice the spokes on the drive side to offset the potential torsional stress on the rotor side from braking. Between the ultrasmooth ceramic bearings, rim stiffness, and hub lacing, the Bora WTO wheels ensure every watt you put out transfers to speed on the road.
