Rim Brake and Disc: A truly multi-purpose wheel, the Campagnolo Bora WTO 33 was developed by Campagnolo using wind tunnel testing to create a wheel that is optimised to slice through the air. Ideal for rolling and flat roads, the wheel is lightweight too to enable you to head uphill without a concern. The Bora WTO 33 wheels have the same aluminium hubs and USB ceramic bearings as the rest of the WTO range. The streamlined hubs are slim in the centre and curve upwards to taller flanges; a shape said to improve aerodynamic performance. Campagnolo's distinctive G3 spoke pattern sees the spokes laced in groups of three on the rear wheel. The wheels are compatible with clincher and tubeless tyres. The 19mm rim width is designed for use with the 25mm tyres common in the pro peloton, though the wheels are also suitable for 23mm and 28mm tyre choices.
