I am going to get a pair of risers for my non x model summit rev. I guess I can only go 2 inches before I have to replace the cables. I am going to get digginsweatswearing's kit. All I want to know is how strong is the steering post. Will I have problems if I go to a certain height? I'm a big guy and I put alot of force on my bars and I don't want em braking on me out in the hills.
