So, my crank is creaking when I climb. I pull the crank and BB, clean and lube everything, and put it all back together. It's still creaking so last night I pull the chainring bolts, clean and lube everything, and get ready to put it all together. I'm not sure how tight the bolts should be so I check the FSA website and see that they advise 120kgf/104in lbs/12nm. No sweat; I take out my trusty torque wrench and T30 bit and get to fastening. The first bolt torques but I've got a bad feeling about it so on the next I back the torque wrench off a bit. I'm tightening the second bolt and as soon as I feel it bottom out, snap, it cracks right below the head of the bolt. I pull the two parts out and can back the broken piece out so I know it wasn't crossthreaded or siezed up, the damn thing just snapped and well below the recommended torque.
So, I've just gotten back from the shop where I picked up a new set of bolts. Anybody want to tell me how tightly they put there on? I really don't want to snap off another one. There's too much nice stuff in my garage that might get broken when I start hurling tools around.
