Bike Fit Series--Post 4--Dartfish Software and Talk on Picking A Frame

Today, we’ll take a look at the Dartfish Video software that master fitter Husam Sahin uses to guide bike fit calculations. Dartfish is another amazing piece of technology that enables Huasm  to determine if cycling posture and pedaling mechanics need improvement. Dartfish reveals problems with joint motions and displays pre and post positions simultaneously using overlay functions that can fade in and out. This software can also show if changes made to the bike affect technique or dynamic fit--for example how an increase in seat height can increase ankle plantar flexion. Between Dartfish and Retul, Husam is able to provide a perfect bike fit, and more often than not solve problems his customers have endured, sometimes for years on end.

In this post Husam also comments on making a frame choice.
