presented by Paul Swift & Katrina Vogel
Paul Swift, owner of BikeFit Systems, and Katrina Vogel provide clinicians and healthcare professionals the opportunity to increase their knowledge and skills regarding bike-fitting with specific emphasis on the importance of the Foot-Pedal Interface. The course will cover the assessment of normal and pathological cycling mechanics, including functional differential diagnosis.
Paul swift is the president and founder of Bikefit. As an athlete he is an 8-time US National Champion. He competed with the US National Cycling Team from 1983 to 1997 racing in the World Championships and World Cup events. He began racing in 1982 as a Junior Category athlete. Paul Swift is the product designer for the cleat wedge, the in-the-shoe wedge, and the bicycle fitting system. Bicycling magazine nominated his "Bicycle Fitting System" one of the most innovative products in cycling. He researched cycling biomechanics forefoot varus/valgus at Auburn University and has been an Athlete's Representative on the USCF's Board of Trustees for eight years.
Katrina Vogel, MS, DPT (Kit) graduated with her Doctorate in Physical Therapy from University of Southern California in 2002. She received her Masters of Science from Western Washington University in Human Movement and Performance with a specialization in Biomechanics. Kit specializes in custom orthotics & biomechanical evaluation/treatment of orthopedic injuries related to running, walking and cycling. She is a guest lecturer in the University of Washington Physical Therapy Department for gait and orthopedics. She teaches continuing education courses (cycling biomechanics/bike fitting) to physical therapists throughout the country and works as a consultant within the cycling industry.

The goal of the “BikeFit: The Foot-Pedal Interface” is to develop the process of clinical assessment and adjustment of the cleat as it relates to lower extremity biomechanics of cycling. Humans are asymmetrical creatures. Yet bikes & pedal systems are designed symmetrically which inherently creates biomechanical challenges for the lower extremities. This course tackles the most crucial, and often misunderstood, connection point on the bike: the foot/pedal interface.
This section looks at the lateral view of the cyclist’s foot. The clinician will begin to understand where the foot should be positioned over the pedal in the fore-aft position, how this is assessed and, most importantly, how to make the proper cleat fore-aft adjustment. Considerations to accommodate cleat adjustments beyond typical shoe/cleat range will also be discussed.
In this section, the clinician will assess the front view of the cyclist. They will understand the relationship between the position/motion of the knee related to the foot. They will identify and go through the appropriate cleat adaptation to bring the foot under the knee including options for lateral positioning beyond the typical capabilities of cleat adjustment on the shoe.
In this section, the clinician will identify and see accommodations for the cyclist’s individual architecture including forefoot/rear foot varus and additional causes for valgus forces moving through the lower extremities. They will begin to understand the types of wedges used to adjust the cleat and/or foot into the proper angle to improve pedaling mechanics.
In this section, the clinician will gain a greater understanding of rotation and float for common pedal systems. The clinician will assess the amount of rotation the cyclist has while clipped into the bike pedal and learn to assess the necessary adjustments to allow for appropriate float in order to avoid frictional torsion between the tibia and fibula.
In this section, the clinician will discuss the difference between a structural and functional leg length difference. They will observe what a cyclist with a leg length difference may present. Discussion regarding types of shimming and techniques used to compensation for a leg length discrepancy will be explained.
Paul and Kit provide a brief conclusion of the Bike Fitting course.
