Black Inc FORTY FIVE Disc Wheelset Shimano HG SilverThe Black Inc FORTY FIVE carbon wheelset is a pro favorite, balancing aerodynamics with a lightweight build. Its 45mm disc only rim eliminates the brake track, reducing rotational mass for faster acceleration and better handling. This all rounder excels on flat, windy sections while remaining light enough to fly uphill. Featuring a 21mm internal width, it is optimized for 2528mm tubeless tires to ensure a flush, aero interface and better cornering.
