I hadn't thought of it that way, where it would assume 1:1 and give you gearing as an output. That's a really good idea.

I was thinking of it basically just spitting out your rollout on the speed calc page along with the other calculated values (which you could do too, but I like the ideas you have as they take away the task of plugging in a bunch of combos trying to get to 1:1). It would still be nice to have the rollout shown on the speed calc page in the results, because you might not always want it to be exactly 1:1. Or for people who are having problems they could input all their info in the speed calc (or a simplified rollout calc) and see if their rollout is too high or too low.

It would really be optimal if you could input any combination of the variables to solve for one that was left out (be it pinion, spur, rollout, tire circumference, etc.), but you are the programmer, not sure if that would be too difficult to do. There is a simple calc on another site that is like this, but only solves for rollout, I can send you the link if you'd like.
