Campagnolo Bora Ultra 50 Tubular Road WheelsetCamapgnolo's Bora Ultra 35 Tubular Wheelset gives the rider champion performance, offering a high level of versatility, lightness, aerodynamics and comfort as well as the high level of performance demanded by Campagnolo wheelsets.The Bora Ultra 50 features CULT ceramic bearings which provide unrivalled levels of smoothness and the lowest friction coefficient thanks to oil lubrication. This makes the bearings 9 times more efficient than standard bearings with the ability to spin for up to 47 minutes when being run at 500rpms.Campagnolo have designed the Bora Ultra 50 Tubular Wheelset to have a wider rim profile from 24.2mm to 20.5mm, allowing a wider tyre to be used, increasing the surface area contact between tyre and road, improving the grip and road comfort. A wider rim also means less excess material is used, taking things back to basics whilst shedding any excess weight to make the wheelset inexplicably light.Engineers at Campagnolo have developed a new construction that gives a far superior braking performance to previous models and other carbon rims. AC3 (All Carbon Control) technology improves braking in the dry by 43% over past versions and an impressive 55% over closest rivals on wetter roads. If you're looking for a pro standard wheelset, the Bora Ultra 50 Weelset (2018) will make you feel like a champion.
