......there is a Brooks saddle that would fit this seatpost on eBay at the moment (item number:- 2175376642). The reason for this style is, to my understanding, that the long narrow rails underneath the saddle allowed you extra adjustment to sit further back or forward than normal (proving to be advantageous for a track sprinter!) The special Brooks saddle would have had Campagnolo embossed on the top of the leather, the narrow Campagnolo clamp fits the standard Record seatpost. best regards Griff King-Spooner (London UK)
