Frankenbike?








I rescued this vintage 64cm Peugeot yesterday. From the 1978 brochure the frame looks to be a PX10LE. The fork decals donít match, the fork maybe from a PRN10E of the same year. Maybe the brakes, seat post and a couple other components match the PX10LE spec sheet but nothing else seems to.

Not sure what to do with this bike. It looks pretty rough and wondering if itís worth rebuilding.

Rebuild to flip, or rebuild to ride?

Once I rebuild one I want to keep it.

I ride Lemond Buenos Aires. I grabbed the Peugeot thinking the frame might be worth having.

First thing, make sure the derailleur hanger can support the rear mech like a normal campy-type hanger.

You needn't spend a lot. You can sell the barcons to pay for new tires. Maybe you can find some down tube shifters at your co-op. Buy top tube cable guides from china ($2). Newbaum's cotton tape is around $10. Rustines hoods may set you back, but they're probably worth it.

Well, it has a SunTour V-GT Luxe currently mounted, which suggests that the Simplex dropout has been threaded for the mounting bolt. But the weird "angle of the dangle" may mean that the PO didn't file a stop for the "B-screw" to bear against to properly adjust the angle.

Remove the derailleur from the hanger and post a picture of the hanger so we can see what's going on.

Or just run the suntour RD on a claw. Very nice bike; this is a PX 10. You likely want to get rid of the brakes. Nothing wrong with mafac competition brakes but straddle cables for them are unobtainium unlike with the mafac racer brakes. I'd just run some cheap dia compe which as a nice match for all the other Japanese parts on this frame. Keep it a frankenbike,

I might suggest riding it as is for a while assuming it stops and shifts, find out what you like and don't like -it might inform the path you take from here, this from Mr. I bought a bike and now I will fill an amazon cart with upgrades I'm old but I'm slow.... but sometimes I learn, sometimes after putting in some miles I even find that the bike I thought would fit doesn't or it does but the rides is only meh. Anyway cool old Pug, nice find good luck whatever path you take.

Nope. Maybe you can cut a stop in it. Or find a Simplex rd.

In the meantime, you can use a claw hanger.

1. It is a PX-10 and that looks like the correct fork and crown - the decals get a little strange 1975-78, but I donít recall ever seeing that crown with chrome epaulets on a PR-10.

2. Find a metal bodied Simplex rear derailleur OR a Shimano Crane (predecessor of the Dura Ace), which will provide its own stop and work correctly with no further modifications. You donít have to cut a notch with those options. The claw would work but it would look awful on that bike!

Dia Compe brakes on a Peugeot? Blasphemy!

Please don't grind - keep it French - Simplex aren't that hard to find and don't scared by the plastic ones.

Bottom bracket is likely French, so both sides will be right hand thread

You will enjoy the ride!

I don't see threads in the mounting hole, so I wonder if it was reamed to take the SunTour's 10mm bolt and held in place by the thin nut on the back side. A Simplex derailleur ought to still work with that. One of the threaded "dropout saver" inserts from Problem Solvers would allow a threaded Shimano Crane or Titlist derailleur to mount. Derailleurs that utilize a B-screw for proper positioning would benefit from a stop tab filed into the hanger, but the purists might object to modifying the dropout in this way.
