The question being asked relates to this weeks new BB failure on the one which has thus far only had 1 damaged crank Monday. The concern was given the bad history on the earlier similar problem with that style spindle if putting another crank on there would just be a repetition of the earlier history of destroying good cranks if it merritted a single replacement try.
I put another crank arm on and the nut worked its way off within 4 miles. So much for that spindle.
I guess I'll replace the cranks.
