Hub - left
Left-side rear wheel hub for Triumph, paired with a right-hand Smiths speedo drive box in the rear wheel assembly.
This is the left-side rear hub, catalog number 37-7070, out of a Triumph parts book. It shows up in the rear wheel section alongside a note that it's used with a Smiths speedo drive box on the right-hand side of the wheel, which tells us this hub is the counterpart piece opposite the speedo drive.

Our record for this one is thin — a single catalog listing tied to a 1979 appearance. We don't have detail beyond that on spoke count, bearing type, or brake drum arrangement for this hub. If you're rebuilding a rear wheel and matching this up against your speedo drive setup, give us a call and we'll work through what you've got before you order.
