Good question! I'm interested in hearing some answers.
I was talking to my dad recently (he has a decades-old entry level racing Bianchi) about how I never learned many handling skills on my old cruisers as a kid and now I feel so far behind figuring out my road bike. I commented that even the cheesy (yet awesome) 'Breaking Away' movie had the guy who could pick stuff up off the ground and reach down and fix his toe clip, among other things, and he's just an actor. My dad said, "um, I could do that too." He used his bike for fitness and commuting. The last time he went out on the bike regularly I was riding on the back in a baby seat, so I never really thought of him as being exceptionally athletic.
I'd love some input on the cycling/bike handling learning curve so I can set realistic goals for myself and keep some frustration at bay.
