For what its worth, on my '78 PR10 I had a couple of gear set ups on it. I didn't like the original 3 arm Stronglight TS, which also had a stripped pedal thread. I had a Sugino GT crank (English pedal threads) laying around, so I tried it with a 52/34 compact set up, which worked out very nicely with the 28t 5 sp rear. The Sugino cranks can also be run as triples. At whenever the last Eroica California was, I found a drilled Stronglight 99 with English pedal threads, and grabbed it. I think it's a 52/36, still with the 28t 5 sp rear (French thread freewheel). I liked the look of the Sugino, but the drilled Stronglight 99 is more French sexy looking, though I miss the 34t granny. If you go to an English thread hub on your new wheelset, you can use a Shimano Megarange 34/14 6 or 7 speed freewheel, which I like very much on my Raleigh with the a Sugino AT triple 52/40/32 (dark green bike). Purists will shriek at the Shimano Megarange, but at 72 years old, still doing big hills, I don't care. You will need a long cage RD for the 34t, but its worth it. First picture is as bought.
