Combining durability, aero-efficiency, and wide tyre capability, the Black Inc FORTY SIX gravel racing wheelset offers a generous 27 mm inner rim width that perfectly accommodates tyres up to 57 mm (29 x 2.2-inch), providing a superior contact patch for enhanced traction and control. The 46 mm rim profile and aerodynamically shaped steel spokes ensure you maintain speed on fast-paced gravel sections and paved transitions.
Durability is enhanced by the high-polished stainless steel bearings that offer smooth, long-lasting performance in all weather and terrain conditions. A larger freehub engagement design (30T X OS 3-PAWL) provides instant, reliable power transfer, crucial for accelerating out of corners and conquering steep, technical climbs. Our off-road hub platform inspired the design, which provides a +25% increase in engagement over standard road hubs.
The Black Inc FORTY SIX gravel wheelset encourages the confidence to push the limits on any terrain, combining speed and stability in one complete package.
