Hey everyone,
Total beginner here, just picked up a vintage Peugeot Randonneur (tube spécial Peugeot 103, made in Beaulieu-Valentigney, France) and I’m trying to restore it for daily use.
I’m stuck trying to remove the rear wheel to change the tires. There’s a bolt I can’t identify – it looks like it has 5 sides (pentalobe?) and none of my tools fit.
Has anyone seen this before on a vintage French bike? What tool do I need?
Attaching photos, any help appreciated!
