FULCRUM SONIQ GR

SONIQ GR 

The GR project has grown out of an in-depth analysis of race data and direct experiences from high-level gravel races.  

The objective was clear: to create a wheel able to support high speeds over rough terrain, whilst maintaining control, precision and a concrete aerodynamic advantage. The heart of the project is the new 2-Wave Rim with an inner rim width of 30 mm, and mini-hook, designed to work in perfect synergy with wide tyres, optimising their shape, contact patch and stability.  

The variable wave profile, with a height of 47/52 mm, improves air flow management and reduces the yaw moment and frontal drag. The Soniq GR uses FF80 fibre, which is less competition-orientated compared to FF100, but that is in any case able to provide excellent overall performance.  

The wheel is completed with sealed cartridge bearings hubs, with adjustable preload, and round spokes. The wheel-tyre system has been developed to work in perfect synergy with 47-50 mm.
