| Let talk sprockets....
What Jay said.... it's a smaller sprocket so therefore a 1 tooth change has more of an impact, percentage wise.
to make it easy, if ya had a 10 tooth sprocket on the front & a 30 tooth sprocket in the rear (a 1:3 ratio), going to a 9 in the front and keeping the 30 would be like keeping the 10 on the front & going to a 33 in the rear. |
