I could do with a bit more adjustment in my reach. Having just swopped to a Brooks saddle it's slightly further back than the old saddle and I have no forward movement left. Now it might be in the right place but as I can't move it forward to try I don't know. So question in two parts really: 1) For adjusting reach is it better to adjust the stem or the seat? 2) Anyone recommend a good road seat post (Dawes Audax) with very fine up/down adjustment and a bit of a forward throw for the seat rails.
