(originally seven speeds) the sprockets are
closer and so the chain is smaller.
Is it enough to count the sprockets,
e.g. does an 8 sprocket casette always have the
same width? Or does that vary
between manufacturers?
And surely there aren't different chains for
8, 9, 10, and 11 casettes, i.e. four different
chain sizes?
