Hugh, The Nitto S-83 are listed as 26 mm of setback. I had one on my Coho (72 STA) but was always sitting on the rivets so I switched it for a Dia Compe Gran Compe with 30 mm of setback.
I've spent many hours looking for setback posts as I have long femurs and can never get back far enough. I've worked with a bike fit expert as I tend to have issues with my right hip. His advice was to get the furthest setback and longest rail saddle possible to get my hip angle optimized. So all my bikes are 72 STA with 30 mm setback posts and the seats as far back as possible. The issue with moving too far back is that your knee will be behind the pedal spindle and you may end of with an overuse injury somewhere in your legs. Or you might end up sliding the saddle way forward and wasting you money. In bike fitting your saddle position relative to the pedal spindle has little to with your stem/bar position. So you should go with a shorter stem if your bar/stem has pushed you back. You may have flexible tendons and not have any issues. The fool-proof option is to go to a bike-fitting specialist which are expensive ( bike shop fitters are barely adequate IME). David ... they are beautiful in an ugly frog sort of way Patrick... the older Dura Ace post are nice but only about 20 mm of setback, but the Flite saddles have long rails so it's a good combo. ( I've used both) ~mike >> > -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
