I've recently bought a new (vintage) frameset from the local bike shop and I have no clue as to what brand or model it is, so I'm crowdsourcing for any information about what make or model it could possibly be.
I'm not much of a bicycle connoisseur, but just from looking at all the parts alone, this is all the information I could gather on my own.
- The frame is 54cm with the number "54" stamped on the underside of the bottom bracket (any correlation?).
- The seat tube has the numbers "5507" stamped on the left side.
- The frame came with a Shimano BB-UN54 sealed cartridge bottom bracket.
- It has Suntour GS rear dropouts with holes for a Portacatena chain hanger (I assume).
Other than that, I haven't gathered anything else, but hopefully these pictures will help.
