CLUTCH HUB -TRIDENT
Steel clutch hub for the Triumph/BSA Trident triple engine, part number 57-2580.
This is the clutch hub for the Trident triple-cylinder engine, part number 57-2580, also carried in older books under T2580. The hub is the splined center piece that the clutch plates ride on inside the primary drive, transmitting engine power from the clutch assembly through to the gearbox input.

The hub is steel, with splines and a keyway machined in, and a tapered bore where it locates on the shaft. This is the three-cylinder engine version, so it's built to the Trident/triple clutch assembly and not shared with the twin-cylinder unit-construction bikes.
We don't have a lot of extra catalog history on this one beyond the basic listing, so if you're not sure this is the exact hub your triple needs, give us a call and we'll go over the fitment with you before you order.
