They were extremely easy to put on. The only issue I have with them is that the throttle tube is very brittle. The other day I was at the track and I went to go help a downed rider so I set my bike down and when I came back and picked it up the throttle tube was broken. I'm on my 3rd set of these and I'm thinking its time to move on.
This is a softer grip that i prefer. I dislike waffle grips and half waffle grips. So I was not sure that I would like the three ridges. Out riding I noticed them at first. Now I love them and I have noticed less arm pump. They have two hard crashes on them and held up well with no damage. That's just me. Find what works for you, but they are worth the $25 try.
