When I did my 1974 Le Tour (now my Son’s) Sheldon Brown was still alive, and was selling a Japanese replacement pedal that was rebuildable, for slim money. I’d bet they have something similar, today.
I bought new Sun rims, laced them with stainless spokes onto the original hubs, the aforementioned pedals, a really cool Truvativ crankset and bottom bracket, an aluminum seat post, a set of Gatorskins, that are still on the bike, a generic, Shimano 6 speed freewheel, and a cheap, but, better seat, and was rewarded with a bike that weighed 22 lbs, with a Greenfield kickstand. I have no desire to return it to what it was. It would be like comparing an F16 to a Saber jet. Dramatically better bike to ride and use.
I suppose a first generation Le Tour could be collectible some day. But, I’ll bet I’m dead when it happens.
Somebody will probably appreciate being able to service the pedals,
Ted
