I believe that before the 1970s, track racers used only cottered cranks
because they were considered stronger and less likely to fracture then
Cotter less cranks. I imagine this is because cottered cranks are built
of steel which is probably stronger and certainly more forgiving than
aluminum. I am not aware of any aluminum Cotter less cranks (I do not
believe that the TA semi cottered cranks really counts as a cottered
crank). Consequently, I believe that cottered cranks are safer than
Cotter less cranks. This is my opinion only, it is not based on
statistics or anecdotal evidence, just my recollection of some distant
