My son and I were getting ready for a ride yesterday, and he was going to ride his 1975(?) PX-10 as recently mentioned on the list. I had gone over to Sears and bought a 7mm Allen key to fit this odd "Peugeot" labeled stem, because nothing I had would fit it and it was, to my eye, dangerously too high. So, we got it loose and as it came out we found it was cracked through in the split region where the expander cone lodges ! Aaron rode his Univega touring bike instead.
I think I could re-machine the stem, cutting it flat above the broken end and then grinding a slot up the side a bit to allow for a new place for the cone expand the stem. Like it was before, just higher. Then, with the remaining length of the stem all the way down in the head tube, it should work...or am I crazy ?
