How to measure your inseam

Your cycling inseam is the single most useful number for getting fit right. Here's how to measure it:

  1. Stand with your back against a wall, feet 6 to 8 inches apart.
  2. Place a book between your legs, spine up, snug against your crotch. This mimics your saddle.
  3. Have another person measure from the top of the book (the spine) down to the floor.

That's your cycling inseam. Watch the full walkthrough here: How to properly measure your inseam
