I've been way happy with mine. No problems with lugs comming off at all. Of course I only have maybe 300 miles on it. I will say that I was a little skeptical about 3'' being that much better then the 2.5''. I was dead wrong...night and day difference in all aspects of riding. As silly as it may sound one of my favorite things is the ability to come to a complete stop going down very steep hills where there is no way a 2.5 would.
I had 2 162's that delaminated. Was a huge PITA so mid season I switched to a new 2.5 It worked fine for the rest of the season. The 3 inch is impressive though and I might try another this season if they got the formula figured out correctly!!!!
