More on Mech hanger, did contact Cotic who as always were very helpful but could not post out any spares out for 4 days, as no one was in the office, Mon Tues and Wed, they also advised they only had very few spares, so to cover my bets, I ordered from Germany also(these arrived first) I could not find any other source in UK. It is bad not being able to use your new bike for a week. I also wanted people to know, not only carry the bolt as a spare, but also the hanger part. I also think there is a problem with the bolt length / thread engagement 4.5mm instead of 6.5mm, that caused the bolt to rip out the threads, which I am trying to clear up with Syntace (as this is not a Cotic design) will update when / if they reply.
