The Fulcrum Soniq 42 Carbon 700c Road Wheelset is designed for riders who want aerodynamic carbon performance with the comfort and versatility to handle everyday road miles, broken tarmac and all-road routes.

The wave-shaped rim varies from 42mm to 47mm deep, helping balance aerodynamic efficiency, stability and responsive handling. Its FF80 full-carbon construction keeps the ride lively, while the 29.8mm external width and broad 29-76mm official tyre compatibility allow the wheelset to be configured for fast road use or greater comfort and grip on rougher surfaces.
