HOW TO MEASURE YOUR INSEAM:
1. Stand with your back against a wall and spread your feet 6"- 8" apart.
2. Place a book between your legs and up against the wall, spine up; raise it until snug against your crotch (this mimics your bike seat).
3. Have another person measure from the top of the book (spine) down to the floor.
