Hub and brake drum
Rear hub with integral brake drum for the Triumph, from the REAR WHEEL parts-book figure, 1974.
This is the rear hub and brake drum for the Triumph, listed in the catalog under the REAR WHEEL figure and tied to the 1974 model year in our records. The hub is the wheel-mounting piece that carries the brake drum as a single unit, so the drum surface the brake shoes work against is built right into the hub casting.

When you're replacing or rebuilding a rear wheel from this era, this is the core piece everything else bolts to: spokes, bearings, sprocket carrier, and brake shoes all reference off this hub. Given the age of these parts, check the drum surface for scoring or out-of-round wear before you put fresh shoes against it.
Our catalog only shows this part turning up in a couple of listings tied to 1974, so if you're not sure this is the exact hub your bike left the factory with, give us a call and we'll help confirm fitment before you order.
