No idea what you have on it now. But, IF you want highway speed, go UP on the front (tranny) sprocket, OR/AND go DOWN on the wheel.
A rule of thumb I use, ONE on the front, is "ABOUT" (operative word there !!!) the same as 2 on the rear.
BUT you have to have the 'snoose' to pull it. So don't be going hog wild, or you'll end up going s-l-o-w-e-r.
IF you 'need' specifics, post back. Need tire circumference (mark tire and ground, roll bike ONE revolution of rear tire, mark the ground, again, measure the distance between the 2 marks on the ground.) Then the back sprocket # and front #. With that info, you can calculate the exact rpm you are turning, etc.
