i know there has been posts about this before, but i couldnt find any (maybe i didnt look hard enough). anyways, I really want to get a little more bottom end and be able to pick up the front wheel a little easier. I just need to know pros/cons for changing the front vs rear, and which one and/or how many teeth to get? thanks. please go easy on me, im fairly new to this site and first time 10 owner.
