The Black Inc 48|58 Wheelset is engineered for riders chasing maximum speed without sacrificing confidence in real-world conditions. Designed to complement the aerodynamic efficiency of the Factor OSTRO VAM, the 48|58 uses a differentiated rim depth setup with a 48mm front wheel for improved crosswind stability and a deeper 58mm rear wheel to maximise aerodynamic performance. The result is a wheelset that feels fast, stable, and predictable across everything from race days to high-speed training rides. A modern 23mm internal rim width paired with a mini-bead hook design is optimised around today’s 28mm tubeless and clincher tyres, improving rolling efficiency, grip, and ride quality. Lightweight carbon fibre spokes and high-flange hubs further enhance responsiveness and stiffness while keeping overall weight impressively low. Fast in the wind tunnel. Fast on the road. Built for riders who refuse to compromise. Key Features 48mm front / 58mm rear rim profile – balanced aerodynamic efficiency with improved crosswind stability Optimised for modern 28mm tyres – 23mm internal width enhances speed, comfort, and grip Carbon spoke construction – lightweight, stiff, and highly responsive ride feel Race-ready aerodynamic performance – developed alongside the Factor OSTRO VAM for high-speed efficiency
