Fulcrum Speed 57 DB C23 Wheels

The new Fulcrum Speed 57 wheels 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 compromise: the new rims, deeper, wider, lighter and more aerodynamic, combine with new hubs and spokes to create a perfect wheel system.
The new wider rims, paired with 28 mm tyres, deliver uncompromising performance, with optimal aerodynamic efficiency, rolling resistance and comfort.
The rim is built using resins and fibres made to Fulcrum specifications. Unlike previous versions, we use a new high-modulus unidirectional FF100fibre composite blend for the Speed 57. Through extensive experimentation, we have achieved the perfect mix of fibres which, together with the correct layup and extremely precise resin control, allows us to create a product that works within the correct elasticity range, ensuring performance beyond its category and a superior ride feel.
