Thank you, that's very insightful and useful Chaadster. It's the frame size that was the big concern right now, because to change that I only have another week or so, and it's good to know that the reach is if anything short (I was worried I was on too large a frame). Everything else, I can (and probably will) play with stems, saddles, pedals etc A LOT - it's fun to do, after all… I am getting used to the lower posture, after only riding mountain frames - you can kind of tell I may be trying to mimic that posture here. So once I get used to being lower it will probably be even better.
If anyone else has any thoughts, do chime in. Thanks again.
