we grind because it's fun if your doing it right, with the right parts i.e hub guards your bike will be fine. if you haven't tried grinding you cant hate on it, try explaining a NY street rider that has no skate parks not to grind its like taking their life away. brake less and brakes combat i run brake less and I'm more careful at the skate park and the street than my buddies with brakes they seem to think because they have brakes they can stop anytime they jump into traffic. I'm in no way trying to argue with you after all i have to respect your opinion.
