Sugino AS cranks - any info?
(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.

Nope, IDK anything about these cranks. The old road cranks with a 144mm BCD that I have are the Sugino Mighty from the 1970's which were copies of the old Campy Nuovo Record and look like the IRD Defiant cranks. Sugino also made a Track version w/o an inner shoulder that mimicked the Campy Record Pista. The cranks in this thread are apparently much newer and are definitely track.

It looks a lot like the Sugino AT, which is a triple crank.
And here I found a photo of the AS with two chainrings

Nice cranks, BTW. I'm using a GLP on my fixed-gear.

More likely someone ground off the inner ledge to make a pretend track crank. More catalog info on the AS here: Sugino brochures early to mid 1980's

Thanks guys for all your input!
Re: grinding off the inner ledge - was that common practice back then? Seems like a lot of work for something that no one would really notice. Oh well.
The plot thickens: I did come across an eBay listing for the same cranks listed as track cranks pulled off a Centurion track bike.
Of course, the Centurion Trac happens to be a pretty rare bird in itself and it's just as hard to find info on what that bike came built with. So i think i've spent as much time as I could getting to the bottom of this. Now to figure out what's for dinner. Thanks again y'all.

There was a guy in that old BF/SS/FG thread, which you hinted at, who stated his AS cranks had ledges for the 2nd ring. In retrospec(?) The best part was when this forums favorite guy...Scrodzilla posted a snarky vid in it
But getting back to now - there is that obvious telltale small ridge...
So much work to have put into a crank that for the most part didn't seem to have had any historical impact?
Dood...do the cranks fit? Can you make them work for your purposes? What the hell else matters?
Good luck & hope you enjoy yours...

Actually, grinding of the ledges may have been necessary to clear the chainstay with a shorter BB spindle to provide a good chainline with a single chainring on the outside of the crankarm spider. That's what I had to do with my Sugino Mighty when I mounted it on my Soma Rush.

i've bought a couple 'claimed-to-be-track' cranks that were ground off. all 144bcd, one was Ofmega the other don't remember.
while it's not terribly common, guess it can be seen from time to times.

I kinda really want that to happen.
