I have stud boy power points and after 2400 miles of riding I think they are junk. Out of 192, 102 are bent and I already replaced 10-15 bent or broken. I am not crazy around cement or hittin curbs. I ride aggressive but damn that is when the snow is plenty deep!! I will not try these studs again. I may even call studboy and see what they say. My wife has 96 in her venom and some of those are bent and she is a very conservative rider.
