What John says...and Roadking, if you have a NOS frame for 500 for me, I take it from you. Size 59 please.
An opportunity for me to be pernickety here...strictly speaking there's no such thing as a NOS SBDU frameset.
They were made to order - not for stock, unless in the unlikelyhood that a dealer ordered a standard size frame in the hope that he would sell it.
A big unlikelyhood. Oh, and by the way 753 is not thicker walled than 531! This comment is from memory only; my own SBDU is in the rarer 531Pro tubing.
John, I am surprised: there are several reasons to doubt authenticity and that is the lack of a frame number(being specific the critical prefix) - examples shouldn't be needed but here they are -
reason #1. The wide availability of 753 stickers and Reason #2. No frame number.
