Introduction to Revolutionizing your Bike Fit

As most avid cyclists already know, riding a bicycle represents fun, fitness, companionship with fellow riders. Unfortunately, most cyclists at some point in their lives have learned their bicycles can also be a source of aches, pains and overuse injuries. There is hope, however. Ongoing developments in bike fit technology, greater biomechanical understanding relative to cyclists’ needs and sophisticated bike fitting techniques have resulted in a comprehensive bike fit solution capable of addressing the underlying causes of physical complaints, and returning the affected rider to comfort on the bike.

What Should A Comprehensive Bike Fit Include?
Since the above suggests the prospect of a bike fit as a source of ‘pain relief,’ it is important to note that not all bike fit providers are created equal. Instead, the achy rider would do well to ensure his bike fit solution of choice marries physical therapy/biomechanics evaluation and treatment, and appropriate technology with traditional evaluation and adjustments to the bike itself. Only then is a bike fit solution truly comprehensive and able to:
  • Accurately evaluate the patient’s physical dysfunction/source of pain on the bike, rather than simply guessing at the problem
  • Effectively translate on-table evaluation and treatment, into on-bike changes in patient biomechanics
  • Determine a short-term bike position that accommodates and facilitates healing by reducing stress on injured/recovering tissues.

As a minimum the following bike fit-related contact point dimensions should be checked (and adjusted, if appropriate):
  • Cleat position – Fore/aft, rotation and medial/lateral
  • Seat height – Fore/aft, seat angle (this dimension is best determined via motion capture technology such as Retül, a goniometer can be substituted not available)
  • Handlebar position – Determined by handlebar stem length/angle
  • Handlebar dimensions – Width, reach and drop (road bike)/brake lever position
The above dimensions have ‘neutral/efficient positions’ for the average healthy cyclist; however, they can also be altered to reduce tissue stress if disorders such as hamstring tendonitis, cervical disc injury, and Achilles tendon injuries are present. The bike fitter must know which dimension must be adjusted in light of the patient’s biomechanics. In addition, the fitter must understand which components might need to be replaced or added to the patient’s bike as part of the bike fit process, e.g., addition of forefoot or rear foot shims to patient’s clipless pedal system to address foot tilt, or changing out improperly sized handlebars to achieve appropriate width. 

At Revolutions In Fitness, a long-time provider of physical therapy comprehensive bike fits, such adjustments, along with physical therapy evaluation/treatment and advanced biomechanical tools such as Retül (motion capture) and Spin Scan (pedal mechanics), have often eliminated patient pain with a single bike fitting session!
