Campagnolo Bora One 50 Wheelset Tubular

In terms of race pedigree, you'd be hard pressed to find a rim that enjoys more time on the podiums of Europe than Campagnolo's iconic Bora rims. With the Bora One 50 Wheelset, Campagnolo brings this proven rim design into the self sponsored racer's range by mating it to Ultra Smooth Bearing USB hubs instead of the Bora Ultra's Ceramic Ultimate Level Technology CULT hubs. While this does result in a pair of differences in the hubs, the Bora One 50 Wheelset is still the one that's reliable and fast enough that certain members of Europcar opted to ride it during a race as trying as Roubaix. The first difference between the hubs is that the USB hub body is alloy instead of CULT's carbon, for a slight sacrifice in weight 50 grams, claimed and stiffness. Second, USB includes the inimitable smoothness of ceramic bearings but without the benefit of CULT's Cronitect races. Despite this concession, the USB system is still a claimed 50% smoother than steel, which is the industry standard. The rims laced to these hubs benefit from the new width of 24. 2 millimeters, up from the previous 20 millimeters. This wider rim is general across the Bora line, and it brings improvements in 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. Like its Ultra counterpart, the Bora One 50 also features Campy's new 3Diamant braking surface, which 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 a microscopic layer of imperfections and resin so that the pads connect straight to a strip of slightly textured carbon.
