This is a brand-new Fulcrum Rapid Red 900 rear hub, removed from a new wheelset. It features a SRAM XDR freehub body, compatible with 11- and 12-speed drivetrains.
The hub shell is made from lightweight aluminum with sealed cartridge bearings for smooth, durable performance. It uses the CenterLock (AFS) disc rotor mount, is built for 12×142 mm thru-axles, and has 28 spoke holes for easy lacing.
Internally, it runs a 3-pawl system with 36 points of engagement for responsive power transfer. The flange diameter is ~54 mm (both sides), and the hub weighs just 330 g, making it an excellent choice for custom gravel wheel builds or as a replacement.
