And the question now: which ones do we keep in the new "racer" category?
- None in a first time, put all in "road" then we change case by case those from the merged "road" category?
- Or we move manually the non-race ones from the renamed sporter->racer?
- Or I create a 3rd new category, "racer", and we move those from "sporter" to either "road" or "racer" before finally deleting "racer"
