I was happy with my saddle position on my old bike, but I haven't got there yet with the new bike (he's called Fergus if that helps). They aren't directly comparable as the old one was a 17" frame with suspension seat post and "comfort saddle", whereas now its a 19" with no suspension. I feel quite comfortable cycling my husbands bike even though I can't touch the ground - and I am still moving this saddle upwards. Are you meant to be able to just touch the ground when sitting in the saddle? I read something somewhere that I can't place my finger on that suggested that you shouldn't start sitting in the saddle and that therefore the saddle could be slightly higher? (Or was that completely rubbish?) Does crank length make any difference to saddle height/comfort position?
