Bora Ultra 35 Carbon Road Wheelset - Tubular

Knowing that it had answered the call in the mountains with its feathery Hyperons, as well as in the flats with its wind-cheating Bora Ultra 50s, Campagnolo felt compelled to deal another lethal blow to the competition. It comes in the form of a gap-bridging 35mm carbon tubular, which the renowned Italian brand is aptly calling the Bora Ultra 35. Perhaps the most versatile race wheel in the Campagnolo family, the new Bora Ultra 35 Tubular Wheelset kills the notion of needing to fill your quiver with different wheelsets depending on your given course characteristics. The simple reason for this is that the all-new rim structure of the Bora 35 was made to dominate all aspects of road racing, not just a specific discipline. In other words, your do-it-all set of Campagnolo tubulars has officially arrived.

For the new wheels, Campagnolo made the decision to employ an entirely new carbon rim structure. While many wheel manufacturers often adapt current layups within their lineups to different mold dimensions, Campy knew that its new Bora required a carbon structure specific to its 35mm depth. As such, the aerodynamically-efficient, featherweight race rim would require a layup all its own. The wheels use a full carbon fiber construction to maximize weight savings and stiffness, as well as a new brake surface treatment called 3Diamant. This treatment involves a process in Campy's Italian facility where a diamond-tipped tool removes resin imperfections along the brake track. Campagnolo states that this process eliminates the impurities and resin deposits on the surface that commonly lead to inconsistent braking. The result of this machining process is a bare carbon surface that, when used in conjunction with Campy's carbon-specific pads, leads to more powerful, predictable braking in both wet and dry conditions.

Accentuating the carbon layup are straight-pull, stainless steel spokes. It might sound slightly archaic to attribute such accolades to something as seemingly trivial as spokes, but the Bora doesn't use an ordinary design. Each wheel utilizes Campagnolo's G3 Geometry to maintain a consistent, perfect spoke tension. Coupled with two of the proprietary Spoke Dynamic balancing spokes, the Bora lacing pattern increases transverse rigidity, which increases power transfer while simultaneously eliminating high velocity vibrations. To further increase stiffness and efficiency throughout the drivetrain, the wheelset features an oversized, drive side rear hub flange. This increases torsional and lateral rigidity, which equates to direct reactivity when you break pace from the line for the final sprint.

Similar to the Bora 50s, the 35's front wheel uses an aerodynamic 18 spoke lacing pattern, while the rear wheel adds durability with 21 G3 rear spokes. The close grouping of three-spoke clusters further contributes to the wheelset's aerodynamics by shielding them from drag on both the drive and non-drive sides. For brake pads, the Boras requires a special set of pads that increase all-weather modulation and power. And to nearly eliminate mechanical drag, the wheelset rolls on Campagnolo's CULT ceramic bearings, set in carbon fiber hubs with the proprietary cup and cone bearing system. Campy also includes its Eccentric-closure system quick-release skewers.

The Campagnolo Bora Ultra 35 Tubular Wheelset comes with a Campagnolo freehub body that accepts 9-, 10- or 11-speed cassettes. The rims, hubs, and spokes come in the stealth Black colorway.
