Fulcrum Speed 57 – High-Performance Carbon Wheels

The Fulcrum Speed 57 represent a new evolution in high-performance road cycling wheels. Developed according to the Form, Function, Fulcrum philosophy, they combine aerodynamics, lightness, stiffness and comfort to deliver outstanding performance on every ride.

The new wheel system features taller, wider and lighter rims, advanced hubs and aerodynamic spokes. The 57 mm rim profile is designed to improve aerodynamic efficiency, while the 23 mm internal rim width allows riders to make the most of modern tyres.

FF100 Carbon Rim

The Fulcrum Speed 57 rim is made from FF100 full carbon, using a new combination of high-modulus unidirectional carbon fibres and resins developed to Fulcrum's specifications.

The precise positioning of the fibres and careful control of the resin create a structure that delivers an excellent balance of stiffness, elastic response, low weight and ride quality.

Aerodynamics and Comfort

With their 57 mm deep profile and 29.3 mm external width, the Fulcrum Speed 57 wheels are engineered to provide high aerodynamic efficiency.

When paired with 28 mm tyres, they offer an excellent balance between aerodynamics, rolling resistance and comfort, making them particularly suitable for road cyclists seeking high performance.
