Why are the sprockets on the crank inverse from the sprockets on the cassette?
If you start from the frame and count outwards, the cassette goes large gear, smaller gear, smaller gear, etc. On the crank, assuming you have a double or a triple, they go smaller, larger, larger.
I know there is a good and probably obvious reason, but I am not mechanical enough to figure it out by intuition. Could someone please tell me?
Thanks.
