Marketing a Bike Fitting Business - Kathy Krumme
Can offering professional bicycle fitting services be good for your
business? Kathy will provide an overview of different ways to
effectively market a professional bicycle fitting service in order to
add revenue and increase profit margins in your business. She will
explore creative and alternative methods of planning a strategy
for your unique business model and budget while addressing the
following questions:
     • What can a professional fitting service to do enhance your
        business and profitability?
     • What constitutes a professional fitting service and what
        training, tools and systems should be in place before
        beginning to offer and market the service?
     • Who is, should be, or could be your target audience?
     • What do you tell them?
     • Where and when do you find them?
     • Why do they want and need your service?
     • How do you accomplish this and how much will it cost?

You may be surprised by how much profitable business can be
generated with a relatively small investment in a pro fitting service

Musculoskeletal Models - Insight into Bicycle Setup and

A vast number of experimental studies have analyzed muscle
excitation patterns and the kinematics and kinetics of pedaling.
However, an integrated understanding of the interactions                                      new image to come!
between bicycle setup parameters, muscle function and pedaling
performance remains a challenge because of the extremely difficult,
if not impossible, task of measuring the governing elements of
muscle coordination, including the neural signals initiating muscle
contraction, the forces produced from these contractions, and the
effects of individual muscle forces on the resulting pedaling task.
Thus, little quantitative data exists describing how muscle forces
interact with the bicycle-rider setup to produce an observed pedaling
motion. However, detailed musculoskeletal models and forward
dynamics computer simulations integrated with experimental data
provide a powerful framework to identify the complex dynamic
interactions within the neuromusculoskeletal system and causally
