Hi everyone,
I have asked a lot of questions here, and I appreciate everyone's input. I am still trying to decide if the frame I got is the right one for me - more and more the answer seems to be yes - but then again, I might just be getting used to it. It's a 56 cyclocross frame, which should be my correct size (5'10, 33" inseam), except the effective top tube is a little longer than my "ideal" by measurements. I shortened the stem by 1cm, that's the only significant adjustment (other than bar angling, saddle back-forth etc.)
I finally got what seems to be the most efficient way to get feedback - a frame from a video riding the bike. Any thoughts? Note it's a cyclocross frame, so it's supposed to be more upright. Here I am in a parking lot so I am not leaning down too far into the drops, but it's not TOO far from my usual riding position in the drops. What do you think of the angles etc.? Too stretched? Not stretched enough? Any use for another pic on the hoods? Does it look like I got the right size?
Thanks!

Looks fine to me, especially the frame size. I might have said the reach to the bars was a bit short, but you addressed that as more comfortable already. Bar height seems high; I'd probaly like to see you lower while in the drops. Definitely looks good enough to hit the road on, and other adjustments will recommend themselves as the time and miles accrue.

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.
