I picked up a PX 10 that I believe is a 73. It has the 531 sticker on the down tube w Nervex Pro Lugs. Interesting the bike came w Normandy Hubs And Champion rims in size 27 1/4. I’m overhauling it now but I was surprised at the geometry. I have another 72 and the 73 seems more aggressive.

Looks like the PO had it built w 27 1/4 rims. The freewheel is a Maeda (suntour).
does anyone recall the park tool to remove the Maeda freewheel? Also if anyone remembers the bearing size would be great.









Pictures up as promised. So I wonder if this is a UX-10. The tire clearance is quite large.
