The new Fulcrum Speed 57 road wheels are the result of a process that took more than 4000 hours of testing in the wind tunnel, laboratory and road tests, in which seven versions of the rim were tested in multiple configurations, with the objective of achieving the best performance in terms of aerodynamics, rolling resistance, lightness and handling. New rims, taller, wider, lighter and more aerodynamic, new hubs and new spokes, make up a perfect wheel system with a weight of 1,495 grams. 57 mm profile, 23 mm internal and equipped with Cult bearings in the hubs for maximum smoothness. Tubeless ready.
