These are awesome grips, they dont move and they feel like sap-covered-rubber-hand-holders. Follow the instructions through, once the srews are tight, then dont screw any further you'll strip your screws and hole. the cover also is really nice and secure and dosn't feel like it will come off. These are great for climbing, when you are in awakerd positions holding on to the handle bars while you power through a super steep section. Get theses if you want your hands to stay in place on the handle bar no matter what your doing.
