Gravel is evolving: speeds are increasing, races are becoming more and more challenging and requirements have changed. This was the driving force behind the creation of Sharq GR and Soniq GR, two new wheels designed specifically for today’s Gravel Races, where riders compete over demanding terrain using wider tyres.
Sharq GR and Soniq GR do not replace the current Sharq and Soniq: they are a natural variant, an extension focused on a precise discipline. In line with Fulcrum’s philosophy, there are no compromises or forced adaptations: every product is designed to express maximum performance and reliability in its specific use.
Connecting the Dots
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 wheel-tyre system has been developed to work in perfect synergy with 47-50 mm wide tyres, which have not only become standard in today’s fastest gravel races but are also the ideal solution for every day rides, where control, efficiency and comfort make the difference. Naturally, wider tyres can also be used, in compliance with the applicable ISO standard.
Specific 45 mm tyres, that in certain contexts have revealed themselves to be technically valid and to perform very well, are also compatible. This combination, which is not currently covered by the ISO standard, has been validated by Fulcrum for certain tyres, following rigorous compatibility tests performed in-house and by tyre manufacturers.
The complete list of 45 mm tyres validated by Fulcrum is constantly growing and can be found at fulcrumwheels.com
The combination between the 30 mm inner rim and the new-generation of wider gravel tyres, opens new pressure management possibilities. The larger air volume of the system allows for a wider adjustment range, to optimize the setup and find the best balance between speed, control and stability in relation to terrain, conditions and riding style.
It is fundamental, however, not to exceed the maximum pressure indicated on the rim (3.5 bar).
Two Models, a Single Vision
Sharq GR and Soniq GR share the same design philosophy and the same performance objective, but provide different technical solutions to meet different requirements.
The Sharq GR represents the maximum expression of Fulcrum’s performance for gravel races: FF100 carbon fibre, hubs with Cup & Cone bearings, flat profile A3RO spokes and 2:1 lacing pattern, for maximum reaction, precision and aerodynamic advantage. Total weight of the system: 1.550 g.
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, for a total weight of 1.695 g.
Both models use the 2-Way Fit™ technology with non-drilled rim bed, ready for tubeless installation without tubeless tape, for a perfectly sealed, more solid structure, which ensures long-term reliability.
No Adaptation, Just Development
Sharq GR and Soniq GR confirm Fulcrum’s approach: developing specific solutions for every discipline, designed without shortcuts and based on objective data and real-world tests.
We don’t adapt existing projects, but we continue to create new ones, designed to respond with precision to the constantly evolving real world scenarios.
