Gear Ratio Explanation

Featured Replies

I've seen gear ratios from 2:56 up to 6:50 in a racing supply catalog. Can someone explain what the ratio is? Like for example, 4:11, does that mean for every 4 rotations, another gear, spline, etc. turns 11 times? If this question has been answered before I'm sorry, I tried looking it up but couldn't find anything:ermm:

Thanks mperdue. Guess I should have tried a further search:stupid: I feel like a doofus. But now I have the answer to my question:classic:
