Dale's observation about the under/over bottom bracket cable routing is very interesting. I noticed that the seller is selling a PX-10 / PY-10 grouppo at the same time as they are selling this frameset.
Among the grouppo parts, there are
a Simplex SLJ derailleur, however, the front derailleur (silver logo) is not matched in color to the rear derailleur (gold logo), and in fact, the front derailleur needs a cable-stop and a cable to route the cable to the front of the front derailleur, but the PX10 frame doesn't have the right routing for it, and
a stronglight-spiedel (decal) 105-bis crankset. This probably nails the year (1976? 1977?), and
a maillard 700 hubset with stenciling, NOT a gold Maillard professional decal. Does anyone know when these were introduced ??
a mafac competition brakeset with the small trapezoid label on the left side of each caliper arm. Anyone know when these were introduced? I saw them NOS at Alex Singer in 2004, BTW.
Can someone confirm the information on when each of these parts was introduced ??
