Question

If i were to put a 22 tooth sprocket on my bike how many tooth free wheel would i put on it?

Answer 1

Depends on your crank length.   Assuming you have 170mm cranks  and you are spinning at 100 rpm, you would get the following.  12tooth -> 10.2 MPH,  11tooth  -> 11.1 mph, 10tooth -> 12.2 mph, 9tooth  -> 13.6 mph.

22 tooth chain wheel is pretty small, so depends on how low you want to go.  

Here is the calculator I used.  http://sheldonbrown.com/gears/
