Technically, "nomenclature" is a system of naming, for example IUPAC in chemistry. So, if you wanted to know the name of something you would ask "what is the name of CH2COOH in the IUPAC nomenclature system", or similar. In common usage, however, people often use "nomenclature" in a looser fashion, for example "what is the name of the set of gears on the back wheel in bicycle nomenclature". We would answer "generally 'cassette', though if you have an older bike it could be a 'free wheel'" even though, technically, there is no formal bicycle "nomenclature", there is a
de facto set of conventional names in the bicycle industry.
(I could be wrong, it is possible that the UCI does have official names for bikes/bike parts. I don't know, I don't find anything in a quick Google search.)
