I have a 2007 BMC fourstroke 03 and I noticed the other day that my frame is missing the bolt for the seatstay pivot. Does anyone know where I can get a replacement? I have tried local bolt/machine shops as well as Hope Depot but they dont carry a bolt with such a slim head. I have also contacted a LBS that is a BMC dealer and they have left multiple messages with no luck, I have also sent them emails with no reply.
