seller measured centre to centre, which is 15" ish, same as my 18" inbred again.
A 15" shred should be a tiny frame i would have thought being all jumpy biased as it is!
Fed up of ebay disputes just managed to get a refund on an evil soverign frame i bought, it never arrived, seller never got in contact. Then found out he had set up account in ex girlfriends name and had been merrily ripping people off for a while! its all a massive ball ache, think this may be my last ebay purchase for some time.
