Kinesiological Approach to Bike Fit: Saddle Tilt
Saddle position is the core of any bike fit. When the saddle is positioned incorrectly, it can cause a wide range of overuse injuries throughout the entire body. Pain or numbness can occur at the hands, wrists, elbows, shoulders, neck, back (commonly low back), knees and feet. This is no exaggeration! Whenever I perform bike fittings, it's not uncommon for me to fix almost all of the rider's problems solely from correcting saddle position. This post will discuss saddle tilt. THE PEVLIS & THE LUMBAR SPINE "LOW BACK" Since the lumbar spine attaches directly to the pelvis, its fate is determined by the tilt of the pelvis. When you tilt your pelvis forward, the lower back extends. When you tilt your pelvis backwards, the lower back will flex. The right amount of saddle tilt is one that lets the pelvis maintain neutral- the healthy balance of flexion and extension.
