Disc brakes on road bikes may look a bit alien next to the herd of traditional rim brake whips, but they're here to stay and will only get more prevalent as the years roll by. Stay on trend and get in on some smooth carbon speed with the Fulcrum Racing Quattro Carbon DB Clincher Wheelset. Providing the fast ride of carbon with the impeccable modulation of disc brakes, these wheels ditch the persnickety, weather dependent, carbon rim braking conundrum to provide powerful stopping in both wet and dry conditions. Fulcrum builds the Racing Quattro with 40mm carbon fiber rims just deep enough to slice effortlessly through the air, and just shallow enough to snap up to speed and tackle climbs with ease. These rims incorporate Fulcrum's Dynamic Balance technology, which is a closely guarded method of laying up the carbon for an impeccable rim balance. This leads to confident stability on the flats, sure handling, and lightning fast responsiveness when you power up the pedals. At the center, Fulcrum laces the Racing Quattro rims to its silky smooth aluminum hubset. These hubs boast oversized aluminum flanges that serve to improve strength and rigidity for a snappy, responsive ride. A two to one spoke lacing pattern on both the front and rear wheel utilizes 14 spokes on the left side and seven on the right to create an exceptionally strong wheel that resists deflection when under the load of disc braking forces. As an added bonus, external spoke nipples at the rim make for easy service and maintenance.
