From FSA USA's own web store (fsaproshop.com, linked from FSA's site as its US webstore); fullspeedahead.com refuses automated requests, so it was not used. S.H.I.S. codes are copied as FSA writes them (FSA uses exact bores such as 49.57 and a 39.78 crown race) and are null where the store gives only head tube outside diameters. Launch years are not published.
