Roues vélo gravel carbone Fulcrum Soniq GR

The Soniq GR Fulcrum s are carbon gravel wheels developed on the basis of race analysis and experience gained in top-level events. They are designed to maintain high speeds on rough terrain whilst offering precision, control and aerodynamic efficiency.

Their 2-Wave rim, with an internal width of 30 mm, accommodates wide tyres for improved stability and an optimised contact patch. The 47/52 mm profile improves airflow management and reduces drag, even at high speeds or on varied terrain, making these wheels a high-performance choice for demanding gravel riding.

Fulcrum brand technologies: 

- 2-Wave Rim: 47/52 mm wavy profile that improves aerodynamics and reduces drag as well as the impact of crosswinds.
- 30 mm inner rim width: optimises support for wide tyres (47–50 mm) for greater stability, grip and control.
- Mini-Hook: provides better tyre/tubeless compatibility whilst increasing safety at high pressures.
- 2-Way Fit (tubeless-ready without a perforated rim tape): simplifies tubeless fitting, improves airtightness and reduces system weight.
- FF80 Carbon ( Fulcrum-specific fibre): offers a good balance between comfort, durability and performance over long distances.
- Sealed-bearing hubs with adjustable preload: ensure smooth rolling, reliability and low maintenance on gravel terrain.
