Dynamic Bike Fit is an INDEPENDENT cycling services company that focuses on individual riders’ needs first. Our processes are based on science and not on myth, hearsay or tribal knowledge. We focus on the rider’s needs using an objective approach and not the sale of a bike. We are focused on improving the individual rider’s overall cycling experience by blending of our passion for cycling, education, technology, and tools. We seek to dispel the myths that pain and numbness are just a normal part of cycling.

When Craig Fulk started Dynamic Bike Fit in 2009, he knew there had to be a better way to position riders on bikes beyond the human eye, static measurements, old formulas, or a protractor on the knee and a string dangling from it. Through much development and revision over the years, we believe we have found a new horizon in bike fitting. That process has become known as our flagship service – DYNAMIC BIKE FIT

Independent of bicycle brands and shops. Our processes and decisions are based on rider needs and not product. We focus on the rider without bias to what type of rider you are, the latest trends, the manufacturers, or favorite bike shop.


Only with us IN OUR STATE OF THE ART CYCLING STUDIO – We implement dual Retul 3-D Motion Capture Systems, gebioMized Saddle Pressure, and Foot Pressure Analysis and advanced foot pressure force analysis in one location. We can analyze both the left and right side of the rider at the same time.


It’s one thing to have the technology – we have the knowledge, experience, and expertise to implement it appropriately.


We look at the whole body, not in part. Our analysis includes rider history, off-bike assessments, on-bike motion capture, and pressure analysis.


We have our roots based on science, not in myth and hearsay.


Our processes, our views, and our implementation are independent of bike brands or products.
