I bought it about two months ago and it has worked as well as it should so far, it was a pain in the butt to swap tires from my old rip to the new one but other then that it works great, oh and keep in mind because i forgot, make sure your rims are the same color, now i have one Chrome rim and the rest are dark grey lol
I've been using these for a number of years now. Can't go wrong with what works. I recommend to all my friends.
Happy riding y'all
