I have no desire to go back to cottered cranks, but I have no experience of one failing. As long as they are installed correctly, and you are conscious of any looseness that might develop, there is no reason why one should fail. I have witnessed people riding where the crank flopped over tdc because the cotter pin was loose. 5 seconds tightening it, restores its function. Are we just looking for things to worry about?

One thing people don't think about; If a cotter goes bad you replace the cotter. If a taper goes bad you replace the whole crank.

For the weight weenies, they weigh more than most carbon fiber entire bikes, for the mechanics they are a pain in the anus for removal, but they will never die...the rings were virtually last a couple of lifetimes. And I guess that is why I like them after all....they are meant and they were built to last, unlike anything made to day. I never really rode one long enough to see if the cotter would actually fail or not. I would imagine that as long as you keep the taper in place with the lock nut , that would do the trick forever and ever....seeya
