It has grips that remind me of my BMX bike from the early 80s, but MADE OF LEATHER. knurled screw. If they come loose, the grip will wobble, which is undesirable with shoulder gear. I would recommend removing the grip by unscrewing the thumbscrew all the way out. Remove those 4 small screws, add some blue Loctite and reinstall. In any case, you do not need to remove them, since all adjustments are made with a knurled screw.
