I'm buying my first tri bike and both shops I've looked at suggested a 61cm frame for me (I'm 6'3). This was surprising since I figured I'd be a 58cm based on the fact that all the pros around 6'2-6'4 seem to be riding 56-58cm bikes. I know there's more to height involved in a fit but I'm just worried that I'm being misled by the bike shops (unfortunately I live in the middle of no where so I can't get fit by someone who doesn't also sell bikes).
Is there a reason why pros would opt for bikes that are smaller than would normally be suggested?
