Cool old PX10! It's nice to see one with vintage hotrodding and upgrades.

Those Phil Wood hubs were expensive then, and they are expensive now. It wouldn't surprise me if they are perfectly fine. Spin the wheels off the bike to see if they are smooth. If they are not rough, you could probably get away with doing nothing. If rough, Phil will pop in new sealed bearings for a fee, or you can do it yourself. The pedals are Lyotard platform pedals. They were great for touring. I had a pair once, wish I would have kept them. I sold them to a small manufacturer who shall remain nameless. It's possible that the pedals were retapped to english threads, but they could still be french. Those pedals were sold with both types of threads. I can't remember if they were labeled differently, you'd have to measure with a caliper to confirm. Or pull them and test thread a std english pedal. If it goes in without trouble the crank has been re-tapped.
