:) i hope your not mounting your own skates, and if you do i hope you know what your doing. front and back is not the only issue when mounting, you have to check wheel clearance from the outsole, you have to check left and right, and you have to detirmine how much hang over on each end you want. Yeah thats why I asked the question, I was hoping that there was a specific way to mount a chassis but I have not come across any instructions on how to do it. Are there any?
