About Us

Your Independent CYCLING SERVICES COMPANY

Independent. Rider‑first. Science‑driven.

Dynamic Bike Fit is an independent cycling services company dedicated to the needs of individual riders—not bike sales. Our process is rooted in objective assessment and evidence, not myths, hearsay, or one‑size‑fits‑all formulas.

Our Mission

To improve every rider’s comfort, efficiency, and performance by matching the bike to the rider—never the other way around—using a clear, data‑informed process centered on the rider.

Our Story

In 2009, Craig Fulk founded Dynamic Bike Fit with a simple belief: riders deserve more than the human eye, static measurements, and a protractor on the knee with a string dangling from it. Through years of development and refinement, that belief evolved into a modern, comprehensive approach to bike fitting—our flagship service, the Dynamic Bike Fit—designed to uncover your position on the bike.

What Sets Us Apart

  • Independent & brand‑agnostic – We don’t sell bikes. Our only bias is toward what’s best for you.
  • Objective, not opinionated – We prioritize measurable data and repeatable methods over guesswork.
  • Rider‑centric – Your body, history, goals, and feedback guide every decision.
  • End‑to‑end process – From pre‑fit intake to post‑fit guidance, we stay focused on outcomes you can feel on the road.

Dynamic Bike Fits

INDEPENDENT AND BRAND AGNOSTIC

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

 

 

LEADING EDGE TECHNOLOGY

Only with us IN OUR STATE OF THE ART CYCLING STUDIO – We implement dual Retul 3-D Motion Capture Systems and GebioMized Active Saddle Pressure Analysis in one location. We analyze both the left and right side of the rider at the same time.

 

 

EDUCATION AND EXPERIENCE

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

COMPREHENSIVE SCIENCE BASED APPROACH

We are rooted in  science, not in myth and hearsay. 

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