When Cyclo-Pedia carried these (as I recall, although it may have been
another source) the advantage stressed was the ability to adjust chain
line. It was not inexpensive. It was sold during an era when Schwinn
Paramounts still came with steel Stronglight cottered cranks, with 151 BCD
Campy cranks as a $25 option (equivalent to about $100 today), and an era
in which track riders all used cotters, since they did not trust the
aluminum cotterless.
Again, it was not a cottered design in the sense we use that term.
Keep grinding those flats!
