Ha I’m not prejudiced! To be fair i’ve run both Shimano and SRAM in the past and haven’t had a problem with either really, not major problems anyway. I do feel the bolt stripped out far too easily in this case though. It was just a case of tightening it to the hanger that did it and I have read of others having similar issues. To be faced with potentially having to throw a whole X9 rear mech out due to a hanger bolt does not leave me with good feelings about the rest of the SRAM kit. The bolt was solid enough that’s for sure, as I took my titanium screw-bit to it but it still resisted turning in the threads, despite drilling out ok. I eventually had to saw through to remove the hanger from the bolt and then again to remove the B-screw apparatus from the bolt too as I couldn’t get the O-ring off either! So there is about a 1mm dip visible in the photos due to sawing on the frame side of the hole for the hanger bolt, which, if I was to replace just the hanger bolt, might cause issues in the future even if it were to function correctly? This is where i’m hesitant as there may be a high degree of tolerance in terms of function if I were to screw a new bolt in as the threads are actually completely intact but there may be nothing to stop it happening all over again with the next hanger. Really B***** annoying is what it is!
