(There was a thread on this dated 2005 but it never really got answered and I'm not trying to resurrect a 10-year-old thread)
So I recently got a pair of these Sugino cranks I'd never heard of (they were thrown in with a wheelset). Initial Googling shows that there was indeed a Sugino AS road double crankset in the 80's, with 144mm BCD. Cool.
But when I installed the cranks, I noticed that the edges of the spider arms (where the chainring sits) don't have space for an inner chainring to fit.
Could there have possibly been a track version of the AS cranks? I mean, there are road versions of Aero Mighty and 75, so it's not that farfetched (except AS wasn't 75/Mighty level). Anyone here know anything about these? I'm keeping them no matter what, I was just curious because I've never seen these before.
