Wheelsets like these weigh only 1270 grams, allowing the bicycle to accelerate and climb more rapidly and faster.

With a focus on outstanding aerodynamic performance, the Black Inc 48|58 wheelset has ensure stability in high wind conditions at all yaw angles.

Developed to complement the efficient aerodynamics of the Factor OSTRO VAM, the Black Inc 48|58 wheelset not only perform well in simulated or wind tunnel testing but offer exceptional performance in real-world situations. The rim design revolves around a shallower 48mm rim section for the front and deeper 58mm rim section for the rear wheel to boost stability in blustery riding conditions. The rim shape enhances this effect with a continuously variable rate of curvature working to improve stability in cross winds.

The 23mm internal rim width combined with the mini-bead hook rim has been optimized for 28mm tubeless and clincher tires. The rims are laced to the high-flange hubs with lightweight and durable carbon fiber spokes to ensure an incredibly strong and immensely light set of wheels.

Tipping the scales at just 1,270g, the Black Inc 48|58 aero-optimized tubeless clincher wheelset weigh less than most climbing wheels on the market. he Black Inc 48|58 wheels are optimized for perfect stability and exceptional comfort, making them ideal whether you are on paved or unpaved surfaces, on steep inclines or on flatter roads.
