ive heard guys on here sayin that they have went 15 front 39 back and it was a good combo didn't take away from the torqy bottom with letting you get a little more out of the top... i ride alot on local mx tracks and climb alot of hills and i left the stock 14 up front and put a 39 out back and which that took my top end but it is real responsive on the bottom and it doesn't lug anymore and i don't have to ride the clutch... but if your for speed start with a 15 front for sure and work with the back for your likes... hope this helps
