When ever you get a new bike there are a lot of adjustments to be made. Unfortunately it's not as simple as taking the measurements from your old bike and applying them to your new one. Every manufacturer has different geometries for their frames so there are always small differences.
For me, I don't really care too much. Put the seat up, lower the bars and away you go. Adjust as needed but purely by feel.
Others are different. Simon, one of the team's hong kong riders, is slightly more pedantic. So much so, that every day he rides for around 1hr longer than everyone else. Going around in circles on the street making millimeter adjustments to seat height, handlebar position etc etc etc.
To make matters worse, to accompany his new bike, he also bought new pedals and shoes which, admittedly, take some getting used to but he took it to a whole new level.
After a six hour ride on one particular day, he spent a further 3hrs riding in circles making tiny changes. By the time he came inside, everyone was ready for bed!
Even After ten solid days of riding and adjusting he still wasn't happy and I am sure he is at home right now fixing something on his bike.
