Campagnolo Bora Ultra 80 Wheelset
Super aero and ultra light the Bora Ultra 80 are not only a seceret weapon against the clock but also the do it all and win road wheel.
The new Bora Ultras have an 80mm-deep rim for tubular tires, having been designed for low weight as well as optimal aerodynamics and wind tunnel tested throughout the prototype phases.
The front wheel has 16 radially-laced, aero-section quad-butted stainless steel spokes varying from 2.2mm to 1.6mm in thickness. The rear wheel has 21 similar spokes that are slightly thinner at their thinnest point – 1.5mm.
The rear spokes are laced seven on the non-drive side and 14 on the drive side in Campagnolo’s G3 spoking pattern. Campagnolo’s spoke anti-rotation system keeps the aero profile slicing through the air, rather than turning the flat side against it after truing.
Bora Ultra 80 wheels have a carbon hub and an oversized aluminum flange. The wheelset’s svelte 1,540 gram/pair weight (715g front, 825g rear) is quite low for such a deep wheelset.
The Bora Ultra 80 is designed to be paired in both function and appearance with 50mm-deep Bora wheels. A Bora Ultra Two 50 wheel on the front with a Bora Ultra 80 on the rear yields a paired weight of just 1390 grams.
Like their 50mm equivalents, Bora Ultra 80s are equipped with CULT-technology ceramic ball bearings running on super-smooth CronitectTM steel cups and cones. Campagnolo claims the CULT-equipped hubs to be nine times smoother than traditional steel-ball-bearing hubs.
The balls and bearings are to be lubricated only with oil rather than grease, yet longevity is ensured by a special bearing surface treatment that prevents oxidation and maintains performance over time.
The new Bora Ultra 80 has been dynamically balanced during manufacturing without adding weights or magnet afterwards; the rim layup is adjusted to be in perfect balance when spinning.
