I have reconditioned many old bikes at my co-op but had never seen these before. The massive pedal ends have bearings in them. They're Deore but there is no part number on them. Anyone know what they're called?

“The Deore pedals were an unusual innovation that never really caught on. Called Dyna Drive in the typical Shimano fashion of inventing new names for everything, the design more or less eliminated the usual pedal axle by incorporating the bearings into a large-diameter threaded stub.”
These are Shimano Dyna Drive pedals and cranks. You can get adapters to run regular pedals on the cranks, but the pedals will only work with Dyna Drive cranks.

Shimano DynaDrive. I don’t know the model number for the Deore, but the Dura Ace is FC-7300.
