u get a seaclamp that fits i think 28.6 r something and put it onto your fork tube, to the bottom and tigten a bit so it can move with a little bit of hammering, make sure your fork has no play and hammer that seatclamp down unitill it can go no more and then tigten it all up. Put your bars on so the bottom touches the top of the seatclamp and tighten up your bar clamp. or just get a sr compression system lol
