Fulcrum Rapid Red 300 – 650B Gravel Wheelset - CA N3W

Fulcrum Rapid Red 300 – 650B Gravel Wheelset

Built from a completely new design philosophy, the Rapid Red 300 wheelset from Fulcrum is engineered for riders who demand versatility across mixed terrain. Designed for modern gravel frames and larger-volume tyres, these wheels deliver stability, durability, and efficiency whether you're pushing the pace on pavement or tackling demanding off-road routes.

Machined entirely from CNC-milled aluminium, the Rapid Red 300 significantly reduces weight while maintaining exceptional structural integrity. A 24 mm internal rim width perfectly supports today’s wider gravel tyres, enhancing traction, comfort, and control.

Thanks to Fulcrum’s 2-Way Fit™ Ready system, the wheels can be run tubeless or with a traditional inner tube, offering maximum compatibility across a wide range of tyre options. Rated for ASTM Category 2, they are ready for real-world gravel abuse without compromise.
