Hub
Rear hub for the quickly-detachable (QD) rear wheel, Triumph PN 37-1593.
This is the rear hub for the quickly-detachable rear wheel setup, listed in Triumph's catalog as PN 37-1593, with the older alias W1593 for those working from an earlier parts book. It shows up across catalog entries running 1965 to 1969, tied specifically to the QD wheel arrangement rather than a standard bolt-up rear hub.

The quickly-detachable design let a rider pull the rear wheel without disturbing the chain or brake linkage, a feature Triumph fitted to certain rear wheel setups during this era. The hub is the core rotating component that carries the spokes and mates to the QD mechanism.
Because this is tied to a specific wheel configuration and not a universal part, it's worth checking your own rear wheel setup against the QD arrangement before ordering. Call the shop if you're not sure which hub your bike is running.
