I'm not talking about raising the bars as such, I'm dealing with the distance from the axle to the crown on the fork. The inch Kona was referring to is there. The bigger tire on front would make up some of this as i said. Look up Axle to crown measurement and I think you will see what I'm saying. I'm currently running an 80mm travel fork on a frame designed for a 100. But the difference in the axle to crown measurements of the two forks was only a half inch. Take a measurement of the fork you have and compare it with the online mesurement of the fork that the bike was specced with and you should know exact numbers.
