The riding is just great! I find myself daydreaming at work about that nights ride. After dinner I look at my wife and she says, "I know, you're going for a ride". Then I get a "be careful" and a pat on the butt and off I go.
I think I have been locking my elbows for the most part and will have to make a conscious effort not to do that, at least for any length of time. I do find the multiple hand positions very helpful and couldn't be more pleased that I took your advice (and the advice of other BF members...don't want to slight anyone) and bought a road bike.
Many of the concerns I had...and you know there were many...have, so far, been put to rest. I've even spent some time in the drops without feeling any discomfort in my back.
