I have the dual compound on my big bike and love them. They are so confortable and durable. I have not had the same problem as el_diablo had. how long have you had yours? maybe they do get messed up after a while, i usually end up geting new ones after they rip in a crash. My uncle has had his since before chirstmas and they are still in good shape. Ill be geting a set for my 50 once i get some real bars.
I have the black and grey and they have came apart. Only the squares have come off though. It does not bother me one bit though, they are great grips. I think the squares come off easier if you get the soft compound.
I had them on my quad for 4 races and the were trashed. I wore the grey all the way to the black layer. All waffles came off to. I don't like them. I go through grips very fast though. The only grips I use now are medium/ hard TAG grips on quad and medium/ soft on 50.
