Campagnolo debuts new Bora Extremely WTO flagship aero highway racing wheels

Who mentioned highway racing is useless? Campagnolo’s new range-topping Bora Extremely WTO household is made for pure highway using and racing. Not gravel. Not all-road. Not journey or bikepacking. And that’s greater than okay. However they’re additionally supposedly extra aerodynamic, lighter, and extra responsive than the present Bora WTO household, and put on a premium end that coincides with their premium pricing.

(Very) delicate form adjustments

Every of the brand new Bora Extremely WTO wheelsets is loosely based mostly on an current Bora Extremely, sharing the identical three out there depths — 33, 45, and 60 mm — and Campagnolo’s G3 longstanding triplet spoke lacing sample. The shallowest Bora Extremely WTO 33 grows barely in inside width from 19 to 21 mm, and exterior width from 26.1 to 27.4 mm, however the 45 mm and 60 mm fashions stick to a 19 mm internal width and an exterior width simply over 26 mm. 

Don’t be fooled by the 33 mm model’s delicate bump, although; all three are aerodynamically optimized for 25 mm tires.

Talking of tires, Campagnolo is decidedly on-trend in that all the Bora Extremely WTO fashions are designed solely for disc brakes and clincher tires (both tubeless or tube-type), the latter that includes the corporate’s newest 2-Approach Match design with its stable outer rim wall. No rim tape is required for the reason that rim mattress is inherently hermetic, and Campagnolo says the brand new wheels are totally compliant with the newest ETRTO pointers on tubeless tire compatibility.

On the floor, none of this sounds significantly groundbreaking. Nonetheless, as is usually the case with Campagnolo wheels, the variations are extra hidden beneath the floor, and require a bit of additional digging.

Externally inside — or internally exterior?

Campagnolo product supervisor Nicolò Martinello is refreshingly open in his opinion that aero highway wheels are extremely advanced today and possibly aren’t going to get rather more aerodynamically environment friendly via adjustments in form alone. Whereas Campagnolo says the Bora Extremely WTO wheels are, certainly, quicker than the Bora WTO equivalents — and aggressive with different leaders within the class — the benefits are discovered not in any drastic adjustments in rim cross-section, however somewhat the novel nipple design.

Campagnolo’s 2-Approach Match rim design is feasible due to the best way its wheels are constructed. As a substitute of holes that go all over the rim, Campagnolo wheel builders thread a brief little bit of metal to every outsized aluminum nipple, which permits them to feed each via the valve gap after which gently information it with a magnet to every spoke gap — a system that Campagnolo calls MoMag. These outsized aluminum nipples aren’t precisely all that aero, nevertheless, so Campagnolo has discovered easy methods to conceal them contained in the rim whereas nonetheless making them externally accessible so you possibly can true the wheel with out eradicating the tire. 

One key change over the usual Bora WTO is the usage of inside nipples for higher aerodynamic effectivity.

The brand new Aero MoMag system options new “polymer” plates which are co-molded into every rim. These plates have particular angles for correct spoke alignment, and likewise function each {an electrical} insulator between the carbon rim and aluminum nipple, and a reinforcing eyelet for the molded-in holes. Throughout meeting, every nipple additionally apparently snaps into place on every of these eyelets in order that the spoke could be threaded on with out fear that the nipple will go rogue contained in the rim someplace.

Though the Aero MoMag nipples are externally accessible, a proprietary software continues to be required to really flip the nipple. You’ll additionally want a approach to hold the bladed chrome steel spoke from rotating, however that’s hardly unusual today. 

On the hook for lighter and prettier rims, attractive new hubs

Regardless of the added inside complexity, Campagnolo has managed to shave some weight out of the carbon fiber rims by utilizing a fancier materials and a extra refined molding approach. Whereas it’s all the time good to drop a couple of grams, what’s arguably extra placing is the brand new “C-Lux” end, which supposedly requires no post-mold sanding to attain its impressively smooth floor. Additional including to the premium look are elegant copper metallic and black-on-black logos instead of a extra in-your-face branding therapy.

It’s maybe price mentioning right here that different carbon wheel manufacturers have additionally been stepping up their end recreation in recent times, with new hookless codecs permitting the usage of steel mould inserts that end in extra constant surfaces (together with decrease weights and decreased manufacturing prices). Campagnolo is sticking with hooked rims for broader tire compatibility, although, which traditionally has required some type of semi-rigid mould insert and sometimes some post-mold machining, too. Campagnolo is tight-lipped on the precise course of getting used right here, however it supposedly combines the advantages of that all-metal tooling whereas nonetheless providing the safety of a hooked rim.

The emblem design supplies a cultured trace as to the wheels’ premium pricing.

All of that is spinning on brand-new hubs which are constructed with a positively pretty form and equally high-polish end, with the entrance sporting a hybrid aluminum-and-carbon fiber shell and the rear using an all-aluminum physique to raised deal with drive torque. Campagnolo’s CULT (Ceramic Final Stage Expertise) hybrid ceramic bearings are used all through, with cryogenically handled metal races and adjustable preload that the corporate claims produces “5 1/2 occasions much less friction than their customary sealed metal counterparts.” 

That clearly sounds fairly over-the-top, however the greater profit to end-consumers will probably be these bearings’ confirmed monitor report of long-term sturdiness.

The spoke holes on the non-disc facet of the entrance hub are drilled straight via the carbon physique.

Out again, the rear hub makes use of Campagnolo’s newest N3W freehub physique design, which is appropriate with the corporate’s 11-, 12-, and 13-speed drivetrains. Shimano HG and SRAM XDR our bodies are additionally supplied.

Worth, schmalue

Claimed weights for the Campagnolo Bora Extremely WTO 33, 45, and 60 wheels are 1,385 g, 1,425 g, and 1,530 g per pair, representing modest decreases of 10-95 g, relying on depth. Nonetheless, all the new wheels additionally boast hefty value premiums of just about 50% over the usual Bora WTO fashions, with a retail value of US$3,585 / AU$4,665 / £2,810 / €3,150 per set (which continues to be cheaper than Zipp’s newest 353 NSW).

Are the brand new wheels price it? Campagnolo wheels could have an excellent monitor report for long-term sturdiness, however going straight by the numbers, the reply is not any, after all not. These could be marginally higher than the usual WTO fashions when it comes to efficiency, however definitely not by sufficient for most individuals to justify the extra price when it comes to worth. 

The spokes on the Bora Extremely WTO are elliptical in profile, not flat bladed.

That mentioned, I dare say that Campagnolo is aware of its goal clients properly, and whereas the lustrous end and beautiful form will certainly draw folks in, it’ll undoubtedly be patrons with extra of an appreciation for “the finer issues” that’ll discover enchantment right here.

A loaner set has simply arrived for a correct check, so I assume we’ll learn how a lot appreciation I’ve for that type of factor quickly sufficient. Keep tuned.
