Fulcrum Speed 57 Rear Wheel - 700, 12 x 142mm, CenterLock, XDR, Black

From Colorado Cyclist

Speed 57 wheels are the culmination of a process that included over 4000 hours of testing in the wind tunnel, laboratory, and the open road to achieve the best performance in terms of aerodynamics, rolling resistance, lightness, and handling, without compromising safety. An evolution without compromises: the new rims (higher, wider, lighter, and more aerodynamic), combined with new hubs and spokes create a wheel system that is sure to make your ride faster. The graphics have been completely redesigned too, and reflect the new Form Function Fulcrum brand identity, with a minimal and at the same time refined design.
