Limit 5, though many are involved with more, I'm sure:
1-1978 Peugeot mixte, 2x5 friction Simplex and I just broke the R shifter. Overhaul for a friend.
2-1976 Schwinn Continental, 2x6 Schwinn group, and boy, is it heavy. Overhaul for a friend.
3-1988 Centurion Ironman Master, 2x7 600 tricolor w/2x7 RSX STI. For a novice locally.
4-1984 Peugeot mixte, 2x7 105 w/upright bars, alloys w/Gatorskins. Will be the end of me....
5-???? I've collected a triple group. Need a frame, 56cm.
