um no, you get a bigger bolt, to go where there isnt an actual hole, and the bolt kinda just fits, and file down the inside part wheres its like an oval, for the same size bot to go.
big bolt back, little bolt front, it does make a difference, i ride my pro like that an it does make it steeper, cuz if you guys were smart youd see that the headtube can go farther forward if the smaller bolt is in the front
