Thanks to you guys and gals i just ordered a 13 tooth front sprocket! I noticed that the 700xx seemed to be geared a little high for me. I live in the mountains and ride a lot of tight and steep trails. I'm hoping this mod. will help me to lug threw some of those tight spots without having to use alot of clutch? I'm not worried about the loss in top end, because i don't race and need more of the power down low. I ordered the sprocket from renthal. Hope it holds up pretty good. It should be here in a couple days then i'll be putting it on! Suppose to be nice this week also and can't wait to see how much difference it will make!
