Campagnolo have rounded out their range of Bora WTO (Wind Tunnel Optimised) carbon wheels with the launch of the new Bora WTO 33.

As the name implies, these are a svelte 33mm deep, making them the shallowest of the lineup, but they've still been optimised to gain as much aero advantage as possible from an all-round/climbing focused wheelset.

The usual Bora features are all present and correct, including the ability to run either tubeless or with inner tubes (2-Way Fit, as Campagnolo refer to it). Interestingly there's no tubular option, suggesting that even their Pro sponsored teams may be moving to tubeless in the coming seasons.

Cup and cone bearings are relatively unusual these days, but Campagnolo (and Shimano, for that matter) are sticking with them - they're easily adjustable and fully serviceable, with the ability to remove play as required, unlike cartridge bearings. Being a Bora wheelset also means that the balls used are ceramic, for low friction with the maximum smoothness and durability.

A 19mm internal diameter is starting to look quite skinny by modern standards, and reflects the race-ready nature of the wheels. Campagnolo say they're optimised for 25mm tyres, although they'll happily run anything from 23 to 28mm wide, making them suitable for pretty much any standard road race conditions.

Campagnolo quote a weight of 1455g for the disc wheelset, so these aren't absolutely ultralight - but we're used to that with the Boras. They're designed for durability, and these 33s are as much about the aero advantage as they are about shedding grams. So, very much an all-rounder with a climbing bias, rather than a pure climbing wheelset.

Rim brake versions are available now, with the Disc brake variant arriving shortly. There's a comprehensive range of freehub options; Campagnolo (naturally!), Shimano HG/SRAM 10/11, and SRAM XDR 12 speed.

We already have the Bora WTO 33 in our online Bike Builder, where you can build your dream bike to your own spec. Or, if you'd like to order a wheelset on its own, get in touch.
