Hmm... if I still had my PX10LE, which components would I want to use today... maybe the Mafac Competition brakes. Otherwise,
modern stuff allows me to dial in the bike and forget about it. I don't miss annual overhauls, steel guides and clips, mediocre shifting,
seized freewheels, loose bearings and their fiddly adjustment, steel seat posts with odd clamping schemes, etc.
