Just wondering why you want to get rid of it? I am actually going through front sprockets, trying to find the right one. I had a 13 and went to a 12, but that gave it to much low tork, but it rev'd out so fast, I am changing to a 14 tonight for a ride tomorrow, and if that dont work, i may go to a 15. I just think if I went to a 15 it would lose alot of low tork, is that the case? Or have you tried it yet?
