Fulcrum’s New Sharq GR, Sonic GR Gravel Wheels Optimize for REALLY Wide Tires

Fulcrum has unveiled its new Sharq GR and Sonic GR gravel wheelsets, engineered specifically for extremely wide tires ranging from 47mm to 50mm. These new offerings feature a 25mm internal rim width, a 40mm rim depth, and a 29.3mm external width, all designed to optimize aerodynamics and performance with the specified tire dimensions. The launch marks a clear commitment from the Italian brand to the burgeoning ultra-wide gravel tire segment.

This development reflects a significant shift in gravel cycling, moving beyond the traditional 38-42mm tire sweet spot towards increasingly voluminous rubber. Fulcrum, a brand with a strong racing pedigree, is responding to the demands of riders seeking enhanced comfort, traction, and potentially lower rolling resistance on varied terrain, particularly in events like Unbound Gravel where such setups are gaining traction. It signals a maturation of the gravel market, where component manufacturers are now designing highly specialized products for niche, albeit growing, segments.

Ultimately, Fulcrum's move is a calculated bet that the future of gravel racing, or at least a significant portion of it, will be ridden on tires that look more like mountain bike slicks. One can almost hear the collective sigh of relief from riders tired of compromise.
