I've been riding bicycles for a bit under a year, and a road bike for about 8 months. I've never had anything resembling a formal fitting, and have been adjusting setup based solely on personal feel -- this afternoon's the first time that I've tried taking photographs, so I might be able to see things externally.
I was surprised by two things in these photographs -- first, how pointed down my toes were; I've lowered my saddle several times in the last couple months, and it _feels_ like me feet are almost horizontal on the downstroke, especially compared to where they'd been, but I guess not. Also, I thought the bend in my elbow was much more subtle than it appears to be. Until 3-4 months ago, I rode w/ my elbows nearly locked much of the time; I've been consciously trying to change that, to better effect than I realized.
I'm probably gunna get a race-specific bike w/in a couple months, and make this my commuter; suggestions w/ this in mind are particularly sought.
