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. http://i1019.photobucket.com/albums/...31CA3C2F8C.jpg 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. http://i1019.photobucket.com/albums/...E664902DB2.jpg https://s-media-cache-ak0.pinimg.com...331187886f.jpg 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. |
Nice looking crank. Maybe Tejano Trackie will know something.

I should also mention that googling "Sugino AS" is a fruitless search.

Did you try googling Sugino A5?

Yeah seems like here are more googles on A5 than there are AS...

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 http://web.fc2.com/jump/?url=http://...gino82_02l.jpg |

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. http://i1019.photobucket.com/albums/...08.18%20PM.png 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 :50:
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... |
Bet it's the same crank.

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 like that theory.

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've got them
I've got the same cranks dude! Those for track
Glad to see this thread :) Cus i was wondering if i was the only one to have a set of those cranks, haha! |
Im pretty sure they are track cranks. I just bought an old Panasonic 4000 Track that came with these same cranks. Doesn't look to be ground down either.
