Is it possible to get a 1:1 gear ratio with a sprocket and chain?

Question

would you have to use the same size sprockets. would the chain affect the efficiency.

Answer 1

I am going to say no it is not possible.  You will not find a drive sprocket as big as a driven sprocket and you will not find a driven sprocket as small as a drive sprocket.

Answer 2

Yes but why would you want to.

Answer 3

Theoretically I suppose you could, but shortbus is correct, they do not make front sprockets the size of rear ones and vice versa.

Answer 4

Yes it is.  Both sprockets would have to be the same size.  Good luck getting it moving from a stop without smoking your clutch.

Answer 5

yes it is possible if you have the same number of teeth on both sprockets.

Answer 6

Two sprockets of the same diameter should give you a 1 to 1 ratio.
