I'm restoring a late 1960's PX-10. My references say they came with AVA bars and stem, but these are supposed to break easily. What decent bars and stem from those years would be appropriate? I have a picture from Bicisport of Merckx on a PX-10, and the stem has an elongated groove. I can't identify it, but it does not look like an AVA.
Thanks,
