Brief Summary

This study aims to evaluate whether an objective, data-driven bike fitting using the id match 3D motion capture system improves power output in recreational cyclists. Participants will complete two cycling performance tests, a 6-second Wingate Anaerobic Test (PPT6) and a 20-minute Functional Threshold Power (FTP) test, before and after receiving a professional bike fitting. The primary outcome is the change in power output on both tests. Secondary outcomes include subjective measures of comfort, pain, and perceived exertion. The goal is to determine whether bike fitting alone, independent of training, can enhance both performance and the overall riding experience.
