[QUOTE=Daven27;21409514]Really nice bike's being presented here!
Nice Panasonic on Tange tubes, seller claims center-center frame is 57cm with a set of brand new continental tires. Not sure if it would be possible to fit bigger wheels there.

With a vintage mountain bike you will very likely be limited to 26 inch wheels. It is not a problem but just don't expect to replace MTB wheels with bigger wheels.
