SHARQ, the latest creation from the Fulcrum Red Room Lab, is designed to elevate the riding experience on mixed terrain, from asphalt to gravel roads. Born from over 4,000 hours of testing and advanced engineering, SHARQ delivers the perfect blend of maneuverability, aerodynamics, responsiveness, and durability, thanks to its revolutionary rim and spoke design.

2-Wave Rim: Innovative Aerodynamics

The 2-Wave Rim (patent pending) is SHARQ’s most distinctive feature. Its profile alternates between 42 mm and 47 mm, combining a symmetrical wave at the nose with asymmetrical waves on the sides. This unique design improves handling and reactivity while ensuring top-level aerodynamic efficiency.

• Rim height: 42–47 mm variable wave profile
• Internal channel: 25 mm, optimized for 30 mm+ road tyres and wider gravel tyres
• Construction: Fulcrum proprietary FF100 carbon fiber and resin mix
• Weight: only 1,440 g per pair
• Crosswind resistance: +21% stability (0°–10°) and up to +30% (10°–20°) vs. traditional rims
• Tubeless-ready: non-drilled, native tubeless design with mini-hooks for safety

A3RO Spokes: Advanced Aerodynamics

To further boost performance, SHARQ introduces the new A3RO spokes:

• Dimensions: 3 mm width, 0.8 mm thickness for maximum aerodynamic advantage
• Anti-rotation system: redesigned hub-spoke interface keeps spokes aligned under load
• No-touching spokes: prevent friction, ensuring long-lasting tension and consistent performance

High-Performance Hubs

SHARQ’s minimalist hubs use Cup & Cone technology with USB™ ceramic bearings for maximum smoothness. Built around a continuous aluminium through-axle, they ensure stiffness, precision preload adjustment, and reliability over time.

Excellence on Every Terrain

The Fulcrum SHARQ is engineered to deliver road-bike aerodynamics and responsiveness while offering the resilience and control required for gravel and off-road conditions:

• Fast and stable on tarmac, even in crosswinds
