So about 50 miles into a 65 mile ride, I was headed into a hill, shifted into my small chainring and my front derailleur comes dislodged from my frame. After stopping, I see that the whole front hanger has pulled away from the frame (see pics), and is just dangling there by one screw... This bike is about 2 months old, with 5-600 miles on it, no reason for something like this to happen. So what do I do? It is still fully covered by a warranty, so that will not be a problem, but what is the actual process? Am I responsible for stripping the bike and sending them the frame, and then re-building it when the new frame arrives? I got this mail order from Competitive Cyclist...

Also, has anyone heard of this happening before? to BMC's or otherwise..

No problem. As far as how to proceed with the warranty, I would contact Competitive cyclist (phone, email) and they should guide you in the right direction. Was your FD properly adjusted?

Are there still threads where the bottom bolt was? if there are, put a new bolt in and make sure they're both tightened.

Whether you built it or some clown at CC, I'm guessing that they didn't tighten the bolts enough. If the bolt got pulled out along with the threads in the frame, then it another problem altogether...

I purchased a BMCTT02 in 2008, the same happened to me in three weeks, it was replaced under warranty, and guess what it went again yesterday 20/6/11. I await to see what they will do. anyone else had the same
