Hyperon Ultratm wheels have all the advantages of Hyperontm wheels, but also take clinchers. The rims and hubs are made from Full Carbontm.Campagnolor composites knowhow is such that it successfully won the challenge of creating a fullcarbon wheel for clinchers. A clincher in fact requires resistance to pumping pressure and blows that is completely unknown in the wheel for tubulars. The result is a pair of wheels whose weight is more than 200 g lighter than the average for aluminium competition w
