Fulcrum Speed 57 Carbon C23 DB

The new Fulcrum Speed 57 mark the step into a new era for Fulcrum, they are the result of the substantial synergy of form and function: form, function, Fulcrum. 
An evolution without compromise: New rims - higher, wider, lighter and more aerodynamic - new hubs, and new spokes, united in a perfect wheel system.
The new wider rims, together with 28mm tires, offer a level of performance without compromise: optimal aerodynamics, low rolling resistance and high comfort.
The resins and fibers are manufactured according to Fulcrum specifications, we use a new composite compound of unidirectional FF100 high modulus fibers for the new Speed 57, unlike previous versions. Through numerous tests we have found the perfect blend of fibers, through the correct lamination and extremely precise control of the resins we are able to produce a rim that offers a perfect level of damping while meeting the highest performance requirements of professionals and guaranteeing a superior riding experience.
