There is a thread that was recently posted here named "sproket". You should check it out, someone posted a link with a calculator that determines the speed in each gear due to the different sprockets front and rear. My opinion, if you're wanting shear low end grunt try a 13t in front and a 40t or bigger in the rear.:cool:

i just put on a 13t and it rips on the low end. Pulls 450's off the line all day long.
