The Good: rubber grip, longevity, lock on
The Bad: I can not think of anything
There is a reason why a legend would put his name on something because it is simply awesome. I have a few pair of these hell I even put some on my wife's beach cruiser, helps her so she doesnt fall down, and every pair has worn just fine. The way I use these is I start by putting them on my "enduro" bike and by the end of the season I could still use them but I just put them on my demo to give them a new fresh start so this means i usually get minimum 2 seasons riding them.
I like the width of these and I do have gorilla hands, I run carbon bars and they lock on just fine with no spinning or special paste needed. You wont be disappointed in these.
