Oh nooooo - not this subject again! How do you determine from his post that he's got one that might break? From what I've seen, the no-date arms seem to break less often.

I've never heard of a broken Record 151 Strada crank (excluding the slender 1958 version)..... Has anyone? I suspect Mark has a "chunky" 144, tho'
