Almost all of my bikes have the Campy 2 bolt posts . I have one bike with a fluted Zeus seat post and they are nearly identical. I find that adjusting the seat angle is a bit time consuming but worth it to get the comfort. I did not have the Campagnolo wrench so I took a 10mm box end (12 point) wrench and bent it. It works well even with the UniCanitor saddles which have even less room than a Brooks Pro!
