Bike Fitting: A Clinical Approach

Bike fitting is a meticulous and highly individualized process centered on a deep understanding of each cyclist’s unique anatomical structure, muscular function, and overall cycling goals. This comprehensive approach forms the base upon which the bicycle is then meticulously adjusted and configured to optimally support the individual’s structural make-up to optimize the individual’s muscular and physiological efficiency. Through the simple concept of always using the data acquired during the comprehensive assessment to help guide all adjustments, there is a higher probability of success at reaching their desired end goals of the Fit, whether it be enhanced comfort, improved performance, injury prevention, or a combination thereof.

A truly successful bike fit hinges on a thorough and insightful assessment of the rider. Without an in-depth understanding of how each body naturally moves, its inherent structural characteristics, and its potential limitations, it becomes fundamentally impossible to properly configure the bicycle. This initial assessment is not merely a preliminary step; it is the cornerstone that provides the crucial knowledge needed to set up the bike correctly. Having a thorough education and understanding of anatomy, physiology, biomechanics, ergonomics, as well as, bike mechanics and the constant evolution of bike development is becoming increasingly paramount in creating a better end result for the cyclist.

During a bike fit, the saddle is the foundational element. The rider connects with the bike at three primary points, with the saddle being the largest contact area and bearing the majority of the rider’s weight. If the saddle fails to adequately support the rider’s pelvis, every other aspect of the fit will be compromised. Poor fitting saddles often lead to compensatory postural adjustments and altered contact points in an attempt to achieve “comfort” or more likely, relief. Therefore, selecting the appropriate saddle is paramount. Once the correct saddle is identified, its positioning is optimized to facilitate the most efficient and powerful pedal stroke. After the saddle is set, the front end of the bike can be optimized for comfort and, if necessary, aerodynamics. I often use the analogy of your car. “Do you ever adjust the engine of your car, to make the inside more comfortable?” Of course not. Your pedal stroke is your engine and your seat height and position is what directly affects your engine’s performance. So once the saddle position is optimized you can then work on the comfort and optimization of the front end. When experiencing a Bike Fit, a large and diverse inventory of saddles is vital. Given the unique nature of each rider, no single saddle will suit everyone, and a broad selection facilitates a more effective fitting process. Some riders will also need to trial saddles prior to landing on the one that provides the right amount of support, pressure relief and freedom of movement to create the highest level of comfort and efficiency.

In short, a Bike Fit is important for all riders and just because your bike came with the parts it came with, doesn’t mean that those parts are right for you. We are no longer just kids riding around the neighbourhood. Our riding has progressed to longer and faster rides and we need to be sure our recreational pursuits don’t cause us pain, numbness or discomfort. For many of us, exercise is our way of managing our mental health. If our escape or stress release isn’t enjoyable, this can cause more frustration rather than enjoyment. So give yourself the best chance to grow and enjoy the sport you love!
