I'm getting a new bike next week, and I was a little curious about the adjustment time I'd need before I struck out on one of my 70 mile journeys or a race team ride. Since I've only had one road bike, and when I make small adjustments to stem positions, seat positions, and even cleat positions, I know that these little things can make big differences. I'm most worried about some kind of pain or fatigue developing, to tell you the truth. Or in a worst case scenario, not being adjusted to the position and getting dumped or crashing on the race ride. Who knows?
