Campagnolo has added a 33mm depth to its line-up of carbon fibre Bora WTO wheels. The new wheelset is available in rim and disc brake versions, both tubeless-ready.

The Bora WTO range was initially launched in 2018 with 60mm and 77mm wheels. The WTO 45 followed last year and is now completed by the WTO 33, which Campagnolo describes as “a truly multi-purpose wheel”.

It’s pitched as an all-round wheelset designed to offer an aerodynamic advantage on flat roads or in a sprint, while significantly reducing weight when the road heads uphill.

The Bora WTO 33 has been tested by the Campagnolo-sponsored UAE Team Emirates and, given that Campagnolo hasn’t announced a tubular version, suggests the WorldTour outfit will be using tubeless tyres at some point this season.

“This profile is a further option when we have to adapt to the different kinds of terrain we tackle over a season,” says UAE Team Emirates rider Marco Marcato.

The Bora WTO 33s weigh a claimed 1,395g for the rim brake wheelset and 1,485g for the disc brake wheelset.

Campagnolo hasn’t offered any numbers for comparative aerodynamic testing between wheels in the range, but says the WTO 33 offers an advantage of 7.5 watts at 45 km/h “compared to a wheel that is not wind tunnel optimised”.

That’s a significant number but it shouldn’t be altogether surprising that an aerodynamically profiled wheel is faster than an (unspecified) non-aero wheel.

The Bora WTO 33 wheels have the same aluminium hubs and USB ceramic bearings as the rest of the 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 Campagnolo also says it’s suitable for 23mm and 28mm rubber. 

Both the rim brake and disc brake wheelsets are priced at €2,160.
