i took some advice (from here i think) that you should be able to sit up from your riding position without having to push away from the bars - if you need to push away then you've got too much weight on your arms/shoulders and need to adjust your position. i tweaked the saddle position on the rail of my hybrid and the saddle height, over the course of about a week before i found the perfect position on it. my roadie seems to be pretty much perfect off the bat though, which is nice. just take your time and move your position in small increments - you'll find it soon enough.
