Correct fore and aft saddle position?

[simmi]

I have just fitted my new stem, it's 120mm, 20mm more than before.
I tried the bike around the block first of all without altering the saddle and have to say it felt much better not so cramped hard to say why just felt a more natural position.
I then moved my saddle 10mm forward which is still slightly back from knee over pedal spindle but not by much.
I will get my bike fitter to check it all still complies to my ideal.

If the saddle moves forward, generally it needs to also go up a little.

Yeah thanks Rob, haven't done it as yet will fine tune it before I ride again

I believe 2 forward = 1 up approx

Surely that only counts if the stem length\reach has stayed the same?

Reading this thread had me shaking my head as I did think that the saddle fore and aft was the definite fixed point of any fit, but on recent rides on flatter terrain had me moving forward onto the saddle nose for power, but once back on the lumpier bits I found I was shifting back on the saddle to my usual position. There is always going to be compromise I guess.

Yes we are assuming that the OP is getting his saddle position set right first then getting the reach sorted out after that , moving around on the saddle for different terrain would then be within this "fit envelope" mentioned.

My setup is quite general purpose and works well for me on the varied terrain I currently ride, but if I was back in Cambridge I'd probably have the seat a few mm further forward to get a little closer to a TT position as there are no hills, therefore negating the desire to shift back on the saddle. Maybe. Pure speculation on my part, but the logic works for me.
