Bora One 35 Disc Brake Wheelset - Clincher

We're used to seeing the mid-depth Bora wheelset getting a lot of action from riders on Team Movistar, UAE Team Emirates, and Lotto-Soudal, and for good reason. It's simply a great all-around wheelset that's light enough to satisfy the climbers and GC hopefuls while summiting hors catégorie climbs during the grand tours, plenty stiff and aero enough for the sprinters during fast 40+ mph sprint finishes and reactive for the always attacking puncheurs over lumpy Ardennes classics with 20% muurs on repeat. Also don't forget that this wheelset survives the 29 sectors of cobbles at Roubaix year after year. This shouldn't surprise us as the Bora name has always been synonymous with blending aerodynamics, excellent handling, reliability, and power transfer since its introduction in 1994. Campagnolo updated the wheels as needed to deal with newer bikes and rider's demands over the years and now with more pros and other discerning cyclists choosing discs for their braking needs, the Bora One 35 Disc Brake Clincher Wheelset is poised to provide race-ready performance and everyday reliability on any ride.

Starting with the rim, the clincher compatibility allows this wheelset to be a little more user-friendly on the days when you're not pinning on a race number. The full-carbon construction is both lightweight and strong and the rims have gotten wider on this newer generation, plumping up from 20 to 23.5 millimeters. This width is designed for the newer standard of 25mm tires allowing for greater volume, better handling and cornering, lower rolling resistance, and an overall smoother ride. The wider rims also contribute to better lateral stiffness for improved power transmission and bolster better aerodynamics when paired with the wider tires. These gains in ride quality also come with an overall weight loss since the cross-section of a wider rim lets Campagnolo use less material while offering a rim of equal strength. The use of a rotor as a braking surface instead of on the rims allowed Campy to further optimize the layup to save weight and focus on the ride quality instead of the heat and pressure requirements of rim braking. Additionally, Campy uses an advanced resin that creates a brilliant finish, without the need for a final clearcoat, that's highly durable, and is UV resistant. Finally, Rim Dynamic Balance technology creates a perfectly balanced rim that is more stable at speed through the use of structural counterweights.

At the center of the wheels are hubs made of aluminum with completely new flange designs to cope with the additional forces and torque transfer across the hub that's seen with disc brakes. Inside the shells are Campy's Ultra Smooth Bearings (USB) using legendary Campagnolo ceramic bearings keeping things rolling smoothly and a user adjustable lockring allows you to adjust the preload for wear while keeping drag to a minimum. Axles come in at 12 x 100mm front and 12 x 142mm rear matching the current spacing on modern road disc framesets and the centerlock rotor mounting allows for multiple rotor options. The freehub body accommodates Campagnolo cassettes.

Campy modified its famous G3 spoke pattern to compensate for the different loads the wheel now faces with disc use. The symmetric, radially laced front wheel used on the rim brake wheel now gets its own version of G3 lacing while the already asymmetric rear receives slight modifications to create space for the rotor and better balance spoke tension between the drive and disc sides.

Campagnolo finishes off the Bora One 35 Disc with a few more thoughtful details. Black anodized self-locking nipples eliminate the possibility of any of the bladed stainless steel spokes from losing tension. MoMag technology allows Campy to place the nipples in the rim without the need for drilling the outer wall of the rim, improving the carbon integrity and stiffness. Campy constructs and lays-up all of the carbon for the Boras in Vicenza, and every piece is X-rayed to scan for imperfections.
