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

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

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

Campagnolofinishes off the Bora Ultra 50s with a few more thoughtful details. Theoversized rear flange nets additional stiffness for power transfer that takesadvantage of the rims\' aerodynamic profile and smooth bearings. The includedquick releases have also been redesigned with an eye toward weight loss andaerodynamics. Returning features include the signature G3 spoke pattern, whichabsorbs road noise and improves power transfer, and rim balancing that offsetsthe 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, andevery piece is x-rayed to scan for imperfections.
