Fulcrum Speed 42 DB 28" wheelset, solid axle, carbon
Evolution without compromise: new rims – taller, wider, lighter and more aerodynamic – new hubs and new spokes come together in a perfect wheel system.
The Speed 42 and 57 are the culmination of a process that involved more than 4,000 hours of testing in the wind tunnel, the laboratory and on the classic road. Seven versions of the rim were tested in multiple configurations to obtain the best performance in terms of aerodynamics, rolling resistance, lightness and handling without compromising safety.
The rim is constructed from resins and fibers manufactured to Fulcrum's specifications, where unlike previous versions we use a new FF100 unidirectional fiber composite blend with a high modulus of elasticity in the Speed 42 model. Thanks to numerous experiments, we have achieved the perfect blend of fibers, which, together with their correct distribution and extremely precise control of the resin, allows us to create a product that works in the right field of elasticity, guaranteeing performance specifications and an excellent driving sensation.
The graphics have also been completely redesigned and reflect the new Form Function Fulcrum brand identity with a minimal yet refined design that includes new icons that provide all the technical information about the product.
