Ensure your saddle is horizontal. If the nose of your saddle is pointing too far up or down, then you may experience discomfort in certain undesirable areas. If your saddle is too far forward or too far back, this can lead to problems with your neck, lower back or arms. If you set both your pedals in the horizontal position, then drop a plumb line from your knee, your saddle is in a good position when the plumb line runs past the shaft of your pedal. You can then play around with setting your saddle forwards or back. But don't make these changes too large, just make minor adjustments to your position.
Would you like help in the fine adjustment of your bike? Then we recommend arranging a bike fitting. Many professional athletes have done this already. During an extensive dynamic fitting session, your ideal riding position is calculated to the millimeter.
