Oct 27, 2011 at 22:35 comment added heltonbiker @DanielRHicks : these kind of spindled cranks could very well not show any "loosening" because it is not tapered like a traditional square one. I think that is why he didn't noticed it untill the very end (fortunately no one was hurt).

Oct 18, 2011 at 15:38 comment added jrockway Should have made that an answer, but don't have enough detail on the problem to really do it well. But basically, if you tighten the thing to the listed spec and it falls off again, the crank is dead and you need another. Whether or not this happens with splined cranks I'm not sure; I had a bike that used one once, but I tightened to the listed spec and everything went wonderfully :)
Oct 18, 2011 at 15:34 comment added jrockway The torque you list is for the bottom bracket cup. Once the crank falls off due to lack of tightness, you need a new crank and maybe a new bottom bracket. This is not true of cranks that are kept on the axle with pinch bolts, but you don't seem to have this type. If you keep tightening the crank onto your perhaps-misadjusted bottom bracket, you can eventually split it. If you can risk it, try tightening to the max listed torque on the crank's bolt. My bike says 40Nm, and that's what I tightened it to. (But mine is a JIS crank, not an ISIS/Octalink crank.)

Oct 13, 2011 at 12:24 comment added Tom77 Didn't notice anything wrong until it fell off...
Oct 12, 2011 at 12:26 comment added Daniel R Hicks I do have to ask: Didn't you notice that the crank arm was loose?
