I've got a 2011 Trek 1.1, and my derailleur hanger broke in a crash a few weeks ago. I've tried both a number 5 and number 6 hanger, which are what WheelsMFG has listed, but neither seem to fit. There is not any damage to the frame, so I'm at a loss as to why these won't fit. The old derailleur hanger is chewed up, and I can't make out what number it is.
Can anyone suggest a better hanger that I can buy?
