Again I have no idea who makes them or whatever. Whoever actually produces specialized frames makes very good products though. The people that broke their frames never really had trouble getting a replacement, it was just that the replacements broke also so they had to upgrade or just sell it. One friend cracked a disc brake tab on 2 different frames, another friend broke 2 2003 giant ac 1 frames, one snapped the head tube off, another friend compressed the seatpost tube on a 2003 ac1 and ended up selling the replacement I believe. One paid a little more money and got a team dh frame and dosent really like it. Plus the shop that sells giants in town dosent really know much about bikes, and isnt a real bike shop.
