After watching my brother set up a road bike (the pedal kind ) for one of his athletes, with the adjustments, measurements, and attention to detail in terms of the correct position on the bike, it got me thinking about the motogp riders and road racers and of the adjustments they make to their bikes depending on their height, weight etc. How would I go about learning about these adjustments? Do they even do this? Where would I start? I dont need you to school me in here if you don't feel like it - but if you could point me in the right direction i would appreciate it.
