The new Fulcrum Speed 57 is Fulcrum’s step into a new era and dimension, the result of the fundamental synergy between form and function: Form, Function, Fulcrum. 

An uncompromising evolution: the new rims - taller, wider, lighter, and more aerodynamic - the new hubs and new spokes come together in a perfect wheel system.
The new wider rims, paired with 28 mm tires, provide an uncompromising level of performance, with optimal aerodynamic penetration, rolling resistance, and comfort. 
The rim is built with resins and fibers made to Fulcrum specifications where, unlike previous versions, we use a new composite mix of high modulus FF100 unidirectional fibers for the Speed 57. Through numerous experiments, we achieved the perfect fiber blend, which together with their correct layup and extremely precise resin control, allows us to create a product that works within the correct elasticity range, guaranteeing category-leading performance specifications and a superior riding feel.
