Bora Ultra WTO: Campagnolo launches the latest and greatest in its iconic line of race wheels

Disc-only Bora Ultra WTOs arrive lighter and more aerodynamically efficient than 2019’s Bora WTOs

Sam Challis – April 2021

Having been produced by Campagnolo since 1994, the Bora wheel line is ostensibly a brand within a brand. The Bora Ultra WTOs are the latest iteration to roll off the production line in Campagnolo’s Vicenza HQ - for all Bora wheels are developed, tested and manufactured in-house.

The new wheels, while similar in overall appearance to the Bora WTO model they supplant at the top of Campagnolo’s racing wheel range, have been wholly redesigned thanks to a ‘considerable investment in production facilities’.

Campagnolo says that has allowed the development of new technologies, which have been applied in the Bora Ultra WTOs to develop them beyond the Bora WTOs. The R&D process has apparently taken nearly three years and has deployed several patented innovations.

As a result, the new wheels are said to be around 100g lighter, more aerodynamic, and a good chunk more expensive too, retailing at £2,810.

 

From the outside in

Coming in the same selection of depths as the Bora WTOs (33mm, 45mm, 60mm), the shape of the Bora Ultra WTO wheeset's rim is broadly similar to the regular version too – the 21mm internal width is carried over for the 33mm rim, while the 45mm and 60mm rims share the same 19mm internal width.

Unsurprisingly the recommended 25mm tyre width for best performance has remained unchanged too.

The rim does benefit from a new construction method though that Campagnolo dubs Hand Made Ultra-Light Carbon, or HULC for short.

Campagnolo says it uses a proprietary carbon composite and a new production method to shed weight and minimise defects.

 

According to the brand, the new rim construction plays a large role in the Bora Ultra WTO wheels' weight advantage over the regular Bora WTOs, which is claimed to be around 100g dependent on rim depth. As an example, the Bora WTO 45 Disc wheelset weighs 1,520g while the Bora Ultra WTO 45 Disc wheelset weighs 1,425g.

The rims also get a fancy new finish too. Labelled ‘C-Lux’, the Bora Ultra WTOs high gloss appearance is a beneficial side-effect of the rim’s fabrication method. It is an attribute borrowed from the construction of Campagnolo’s carbon cranks, which similarly come out of the mould with no finishing required.

 

Campagnolo says because the rim doesn’t require lacquer, the finish is harder-wearing and the rim itself can be lighter.

Most unusually, the glossy C-Lux finish even extends into the rim channel. Being undrilled anyway (the spoke nipples are inserted through the valve hole and positioned in their seats around the rim using a magnet – more on that later), the rims don’t need to be taped to be tubeless compatible.

Campagnolo says the combination of these two features creates a precise, smooth surface, ensuring tubeless tyres are safe and easy to set up.

 

Novel nipples

High-end Campagnolo wheels have used the brand’s ‘Mo-Mag’ nipple technology for several years but the Bora Ultra WTOs build on that feature with a few key updates.

The new wheels use an ‘Aero Mo-Mag’ design. The nipples are still guided into seats within the rim chamber via a magnet, but where in the past Campagnolo has brought the nipples through to protrude and attach to the spokes externally, that connection is now made internally.

The nipples are totally hidden, which together with the elliptical spokes used in Campagnolo’s G3 lacing pattern can potentially result in cleaner airflow and better aerodynamics.

Campagnolo has cleverly averted the maintenance pitfalls of traditional internal nipples too, allowing external spoke tension adjustment to be carried out using a supplied proprietary spoke key.

 

Hub upgrade

Both hubs use the same hourglass shape as before which is said to maximise aerodynamic efficiency, but the front hub has received some exciting redevelopment in terms of construction material.

The hub body (aside from the brake-side flange) is now made out of unidirectional carbon and has been given the same C-LUX finish as the rims. It apparently makes the hub lighter but perhaps just as importantly, infinitely more handsome.

 

Befitting the Bora Ultra WTO’s top-of-the-tree status, the hubs are outfitted with Campagnolo’s finest CULT ceramic bearings, which the brand says produce 40% less friction than standard steel bearings.

In a neat example of the bearings’ purported efficiency, Campagnolo says from 78kmh a CULT-equipped Campagnolo wheel will take 2 hours and 45 minutes to come to a standstill.

The wheels have already been used extensively in the WorldTour, apparently finding favour in the bikes of Caleb Ewan, Greg Van Avermaet and Tadej Pogacar.

Cyclist was given a set of Bora Ultra WTO 60s ahead of the launch so has had the opportunity to put together a review. Check out our thoughts on how the Bora Ultra WTOs perform for those of us not gifted enough to ride in the WorldTour.
