if your removing them to replace them, the quickest and easiest is to cut them off with a sharp knife, from the inside of the bar to the tip and peel them off, its then easy to scrap off the grip and glue. Make sure the bars are clean and dry before reapply new grips, scuff the bars slightly and glue the grip and slide on and leave over nite or 5 hrs to dry properly, use grip glue its worth it and stays on good...dd
