Step 2 Measurements

First, measure your X-seam size. X-seam is the distance from your back to your feet in a recumbent (sitting) position. The best way to do this is to sit upright against a wall with your feet outstretched and measure the distance from the wall to your feet.

Alternativly, you can use two chairs. Sit upright in one chair and place your feet on the seat of another chair. Have an assistant push the second chair until your feet reach them. Then measure the distance between the seat backs.

This measurement simulates the distance between your seat and the furthest point on the crank.
