Campagnolo launch Bora WTO race wheels

Claimed to be the most aerodynamically efficient ever made, the new WTO (wind tunnel optimised) wheels have seen Campagnolo ditch tubular and offer them as tubeless-ready clinchers only

Legendary Italian component brand Campagnolo are on a roll to celebrate their 85th 

anniversary, with the 

new Bora WTO race wheels launched on top of the 

12 speed Super Record and Record groupsets announced this morning.

WTO 

stands for 'Wind Tunnel Optimised', and is the latest development in Campag's 

widely commended Bora 

series. Not only do they claim to have conducted the most exhaustive aerodynamic study Campagnolo have 

ever done, but the findings have also led them to ditch tubular entirely and just make them as one clincher set with a tubeless-ready converter kit included. This means even the pros running Bora 

WTO 

will be on 

tubeless 

tyres, because according to their research, 

Campagnolo 

insist it's 

the out-and-out fastest way to go.

They will be available in 60mm 

or 77mm 

depths (with the 77mm 

front wheel-only as it's intended to be paired with their Bora 

rear disc wheel for time trialling) and have a completely new rim design 

to the Bora 

One and Bora 

Ultra wheels. Campag 

based their wind tunnel testing 

on real-world conditions, trying out many different angles and wind speeds to replicate what a rider faces out on the road. This 

was also supplemented 

with ride data collected on two different continents, and wind tunnel testing was always conducted with a rider on the bike to make the findings more accurate.

Campag 

have opted for the C19 

width for the rims, which provides a much better fit with 25mm and 28mm tyres to create a more aerodynamic shape 

overall. Perhaps the most interesting findings were with tyre choice: testing 

tubular, clinchers and tubeless tyres, Campag 

found that tubulars were the slowest option, then clinchers, 

and tubeless were fastest. It's led them to drop tubular versions of the new wheels altogether, which 

mean pros using the new wheels will be riding tubeless. The rest of us can run them as clinchers, but just need to add the conversion kit to go 

tubeless (no rim tape required thanks to Campag's 

MoMag 

technology). 

Other aero innovations include new curved hubs, and even the spokes are shaped for aero efficiency. To get the shape they wanted the spokes are made from machined alloy, possibly adding some weight but making that all important more aero shape. The 60mm 

wheels have USB 

ceramic bearings and the 77mm 

wheel features the super high-end 

CULT ceramic bearings.

Campag 

have also worked hard to keep the 

weight as low as possible, with the 

60mm 

pair coming in at 

1540g 

and the 

77mm 

front wheel just 

745g. They 

don't have a landing date or price as of yet, and at the moment are rim brake only; but we'll be keeping an eye out for their arrival and any news of disc versions in the near future...

Arriving at road.cc in 2017 via 220 Triathlon Magazine, Jack dipped his toe in most jobs on the site and over at eBikeTips before being named the new editor of road.cc in 2020, much to his surprise. His cycling life began during his students days, when he cobbled together a few hundred quid off the back of a hard winter selling hats (long story) and bought his first road bike - a Trek 1.1 that was quickly relegated to winter steed, before it was sadly pinched a few years later. Creatively replacing it with a Trek 1.2, Jack mostly rides this bike around local cycle paths nowadays, but when he wants to get the racer out and be competitive his preferred events are time trials, sportives, triathlons and pogo sticking - the latter being another long story.
