Dynamic Fit




Dynamic Fit Principles



Dynamic bike fit is an iterative process whereby the graphic video biofeedback provided by the SpinScan™ is used to evaluate the impact of small adjustments to the bike position. The SpinScan feature provides a multi-color torque graph, which represents one full 360-degree pedal revolution divided into 15-degree segments. It will identify “flat” or “dead” spots in the pedal stroke where optimal power is not being transferred to the drive train. This feature is given a quantifiable measure. If our muscles were able to produce equal torque through the full 360-degree peal revolution, the number would be 100. While this is the physically impossible, a number between 70 and 90 is considered to be very efficient transfer of power




Balanced Power Distribution



The balance of power distribution between the left and right leg as a percentage of 100 can identify strength imbalance as well as bone structure (leg length discrepancies) or soft tissue (flexibility) limitations. Once identified, this issues can be addressed.


Objective Evaluation

The torque information, along with power and heart rate data, allow us to make objective evaluations of the effects of lowering bars or moving the saddle forward or back into a different position. After an initial pedal stroke evaluation most riders can improve pedaling efficiency by as much as 20-25%.
