Fulcrum Racing Speed 42 Disc Brake

The new Fulcrum Speed 42 are Fulcrum’s step into a new era and dimension, the result of the fundamental synergy between form and function: Form, Function, Fulcrum.
An evolution without compromises: the new rims – higher, wider, lighter and more aerodynamic – the new hubs and the new spokes come together in a perfect wheel system.
The new wider rims, paired with 28 mm tires, provide a level of performance without compromises, with optimum aerodynamic penetration, rolling resistance and comfort.
The rim is constructed with resins and fibres made to Fulcrum specifications where, unlike previous versions, we use a new composite mix of FF100 high modulus unidirectional fibres for the Speed 42. Through numerous experiments we have reached the perfect mix of fibres, which along with their correct layup and an extremely precise control of the resin, allows us to create a product that works in the correct elasticity field, guaranteeing hors catégory performance specifications and a superior ride feel.
