    The debate between clinchers and tubular tires may never be settled. Ride quality vs. rolling resistance vs. weight vs. aerodynamics vs. cost … We won’t try to stoke the debate, but there’s one recent development that will definitely swing the argument in the clinchers’ favor: the Campagnolo Bora Ultra 50 Clincher Wheelset. Aside from the addition of the clincher option, the Ultra 50 has seen another significant change — Campagnolo has bumped the Bora rims' width up to 24.2 millimeters wide at the brake track. By doing so, the Italian manufacturer has incorporated a key piece of modern innovation into the storied tradition of cycling's most beautiful wheels.

    The new width brings huge dividends to the Boras, including better handling and cornering, lower rolling resistance, and a smoother ride. It also nets better lateral stiffness and — in a counter-intuitive twist — actually improves aerodynamics. The width also saves weight by letting Campagnolo build a more structurally sound rim with less material, and it means you can mount bigger tires, up to 27 millimeters, for a tubular ride that's more plush and durable than ever.

    The CULT cup and cone bearings are behind Campagnolo hubs' legendary rolling performance. CULT marries the smoothest ceramic bearings with thermochemically treated Cronitect races for a claimed 3.5 more watts per pedal stroke over non-CULT bearings. The interface between the ceramic balls and Cronitect races is so smooth that they virtually don't wear out and only require a thin film of oil instead of grease. All told, Campagnolo touts these as the lowest friction bearings in the world. While we normally approach anything that smacks of marketing hyperbole with healthy skepticism, taking the Boras for a spin lends credence to Campy's claim.

    A good wheel can't just go well; it also has to stop well, and the new 3Diamant braking surface addresses some of the key braking issues we've had with carbon rims in the past. Campagnolo literally uses diamonds to hone the brake track to near perfection, removing imperfections and resin so that the pads connect straight to a strip of slightly textured carbon. This reduces the time it takes for the brake pads to grab the rim and it all but eliminates the usual breaking-in period for carbon brake strips, increasing stopping power by 40% in wet conditions and 20% when it's dry. It also removes any surface imperfections in the wheel for a pulse-free operation.

    Campagnolo finishes off the Bora Ultra 50s with a few more thoughtful details. The oversized rear flange nets additional stiffness for power transfer that takes advantage of the rims' aerodynamic profile and smooth bearings. The included quick releases have also been redesigned with an eye toward weight loss and aerodynamics. Returning features include the signature G3 spoke pattern, which absorbs road noise and improves power transfer, and rim balancing that offsets the nominal imbalance caused by the valve stem hole and associated hardware. Campy constructs and lays up all of the carbon for the Boras in Vicenza, and every piece is X-rayed to scan for imperfections.

    • Familiarity: I've put it through the wringer

    Campagnola make such a high quality product that does what they claim. These Ultra 50s have been ideal on both hill and time trials. So smooth and so quiet. Its almost effortless to maintain speeds at 30 mph on flats. If you have the $ you won't be sorry.
    PS also the perfect match for my Cipollini! Italian bikes love Italian wheels!

    Can these run tubeless?

    Hi Gregroy,

    These wheels are not advertised to be ran as tubeless from Campagnolo. I have read that some people have run them as tubeless due to no spoke holes but ideally are not designed for that. Let me know if you need anything as I am a Personal Gearhead here and can help with anything you may need.
