Fulcrum Speed 42 Disc 2WF C23 AFS USB HH12-100 HH12-142

Fulcrum Speed 42 Disc C23 carbon wheelset 2024

The new Fulcrum Speed 42 Disc 2024 carbon wheels mark Fulcrum 's entry into a new era and dimension, the result of a fundamental synergy between form and function: Form, Function, Fulcrum .

An evolution without compromise: the new rims - taller, wider, lighter and more aerodynamic - the new hubs and the new spokes combine to form a perfect wheel system. The new wider rims, combined with 28mm tires, deliver an uncompromising level of performance, with optimal aerodynamic penetration, reduced rolling resistance and increased comfort.

The rim is constructed with resins and fibers specifically designed to Fulcrum specifications. Unlike previous versions, for the Speed 42 we use a new composite blend of high modulus FF100 unidirectional fibers. Through numerous trials, we have achieved the perfect blend of fibers which, with their correct arrangement and extremely precise control of the resin, allows us to create a product working within the correct field of elasticity, guaranteeing performance specifications beyond category and a superior driving sensation.
