Basic Bike Fitting Concepts

  • Your bike should be determined per your bike riding style.  Do not get fit to a particular bike that you just happen to like.
  • Don't let the bike determine the position that you ride in.
  • Your bike fit should find the relationships with a particular bike and your riding position.
  • A good bike fit will encourage better bike technique.

What is Motion Capture?

  • Video is taken of a rider in various positions while pedaling
  • This is usually done on a sizing cycle for a fitting
  • One can see exactly what a rider under load is doing
  • Motion capture offers a more precise fitting

This video mostly discusses 2D analysis via Dartfish.  Comparisons with 3D systems, RETUL are also made.

  • 3D systems can more quickly calculate rider angles but with 2D a rider can see himself and not just be rendered into a stick figure.
  • Key angles such as ankle, knee, hip, shoulders and elbow angles can be precisely determined.
  • Before and after side-by-side analysis can be done.
