That warranty notice sounds like a dodge. As Carleton mentions, the trackends (not dropouts - come on, we're trackies) bend because they're cantilevered backwards from the seatstays, and, if there's weight going down on the saddle, it's force on the axle pushing the top arm of the trackend upward.
i mean, look at how thin and spindly that is!
the revised trackends are shorter with a lot more carbon (i assume - could just be metal painted consistent with the carbon it's molded into) above them. should serve to reinforce it, but removes some usable trackend space. Really the best thing for Dolan to do would be to have the seatstay come down on TOP of the trackend, rather than forward of it.
