Can anyone answer why a person shouldn't just change the stock top sprocket of 22 teeth to a 21 tooth and stay with the stock lower sprocket of 41..... The final ratio would be 1.95, the same ratio as a 20 tooth top and 39 tooth bottom??

What is the purpose of changing BOTH gears when you can simply change just 1 (the top) to achieve the same final ratio?? Thanks.

I'm no expert, but I was always under the understanding that you needed one even and one odd gear, that the chain would bind with two odd or even gears. Maybe that's a myth, but it makes sense to me, the length and # of links in the chain are usually not changed when people change gears.

Anybody else?? Am I way off here?
