Black Inc Forty Five Wheelset

Designed with an optimal balance of aerodynamic performance and lightweight for riders who want a single wheelset to do everything from high mountain Gran Fondos to flat road races to long training days, and everything else in between.



The Black Inc FORTY FIVE wheelset is the perfect partner to the OSTRO, balancing aerodynamics, lightness, strength and stiffness. Its performance is driven by a proprietary rim profile and our new ratchet driven hub. The FORTY FIVE is disc-only, tubeless-ready and optimised for 25-28mm tyres, with an internal rim width of 20.7mm. The new Black Inc hubs run on CeramicSpeed bearings and feature an aggressively machined, lightweight freehub.
