What is the name in English of the part that has a set of dented wheels and goes attached to the center of the back wheel of a bicycle?
What would be the name(s) in English of the tool that allows to remove these dented wheels so that I can replace a broken spoke?
I have had bicycles all my life, but now that I left my country of origin buying tools and parts using a language that is not my mother tongue is a bit challenging sometimes.
(If anyone can provide the same names in French that would be even better).
