Fulcrum Speed 42 DB wheels

The new Fulcrum Speed 42 wheels are Fulcrum's first step into a new brand era and dimension, Form, Function, Fulcrum, in which form and function are the core concepts. An uncompromising evolution: new rims-higher, wider, lighter and more aerodynamic-new hubs and spokes go to make up a perfect wheel system. The new wider rims, coupled with 28 mm tires, are able to offer an uncompromising performance combination in which aerodynamic penetration, rolling resistance and comfort find their best expression. The rim is made using resins and fibers made to Fulcrum specifications where, unlike previous versions, a new composite mix of FF100 unidirectional high-modulus fibers is used for Speed 42. Thanks to extensive experimentation, the perfect mix of fibers has been achieved, which, combined with the correct positioning of the fibers and a very precise control of the resin, makes it possible to obtain a product that works in the correct elastic range, guaranteeing top performance characteristics and a superior riding feel.
