I got a team edi but i changed the head set to a canecreek S1 , after i tighten it all the way and put on my bar it will get lose after a few hours of riding . Is this because of my clamp not clamping properly or does all threaded fork has this problem.

thanks

Yes i used the lock nut that the fork comes with and tighten everything super tight but it still comes lose , could it be the clamp?
