Review on 🏁 Enhanced Performance: RaceFace Half Nelson Locking Grips - Unmatched Grip and Control for Racing Enthusiasts by Nick Nigerson

They are comfortable and controllable, but there is a design flaw. The end cap is designed to clip onto the end of the handlebar. The problem is that the end cap compresses the tip so that when tightened it pushes away from the end of the rod. There should be a lip or groove for the end cap to fit into to keep it in place. I just used my stock end caps to get through as I like grips that work well, but this is a fairly obvious design flaw that any engineer or researcher should notice. I'm surprised Raceface hasn't fixed this issue.
