This post is a quick one asking the question whether the GC Open Data Project cyclists cluster into distinct phenotypes? I used the 2nd and 3rd principal component scores from the 3 component model (see Part 2 and Part 3).
The short answer is that it doesn’t look that way, to me anyway. I don’t see any worthwhile clustering to suggest that a single category label such as sprinter or all-arounder would better describe relative abilities better than the radar charts. If needed cutoffs could be chosen in some statistically sound manner. But in this case its better to just let the data speak for itself.
