Sit flat on the floor with your back against the wall and measure from the wall to the bottom of your feet. Hold your feet 90 degrees to the floor. Each X-Seam range is given per bike model and frame size in the model specifications list below.
Be sure your back is against the wall and your legs are flat on the floor. X-Seam measurements may vary. If you're close to either end of the X-Seam range, be sure to have your Dealer verify the fit.
