Same basic rules apply. So just watch any of the videos and read articles about fitting yourself to the bike. With bikes that are too big for you, you might have to just learn to live with not being able to get to your ideal position. Some people don't tolerate but a narrow range of fit. Others can tolerate a wide range of fit. If you are the latter, you'll have less issue with the wrong size bike.

Welcome to BF. If you have an actual fit problem, then start a new thread and tell us about it and your bike. Maybe someone can suggest something.
