Greetings Everyone,
Presuming that you had a frame that you knew was either made of 531P, or 753 (spec'd with the same tube wall thicknesses), would there be a way to tell which it was?
Unfortunately, I don't have an identical sized one of a known material to compare weights with. Would there be some way to tell by the appearance of the brazing material, or a stamp on the tubing somewhere?
Thanks,
John Barry Mechanicsburg, PA, USA
