I see what you mean but maybe these seat stay ends are slightly slimmer and shorter in length?Bob Jackson springs to mind but I have no idea why
Frame number is helpful because it's easy to eliminate contenders
This is true...just a slight problem...I don't own the frame and I like to think of myself as a fair and just man...allegedly. But If I give the owner more information I may not get the price I am offering? Is that a terrible thing? Did I say that I have to pay £20 train fare? lol I feel bad nowGet that frame number out - otherwise it's pure speculation
