chainring quest

I'm after a new chainring and despite looking high and low, can't find what I'm after.

-48T
-130bcd
-3/32"
-for 5 arm crankarm
-Silver in color
-with cutouts (like the Sugino Mighty Comp or even the TA rings...some sort of cutout. I know I can get the Rocket Rings or Salsa or Surly rings, but I really don't like the solid chainrings in terms of looks.)

If anyone knows the secret to locating one, I'd be happy to hear from you!

Hey Aeroplane,
Thanks for the offering...but the only ring in 130bcd & 3/32" is that Sugino 130J. That is just one of the solid rings and I'm hoping to find one with some nice cutouts.

Yep, here are 2 old shimano 600 rings that I have:
(52/42, ca. 1980, no they're not for sale)

Problem is that you're rarely going to find anything between 42 and 50 in old road rings.

Yes, thank you for pointing that out Landgolier. 48 tooth is not easy to find in an older road ring.

Yes, the pictures that BostonFixed posted are what I'm after.

So...anyone have any suggestions? I'm still striking out...

Some variations on the rocket ring/basic chainring from danscomp or harris actually have cutouts like that, I actually have a 48 like that come to think of it. They have that whole two sets of holes thing, but they do kind of have that look.

Looked at Dan's Comp and they all look like BMX rings to me or 4 spider arm rings. Have looked at Harris a bunch and not able to find what I'm after. Even the ring that is on the Sugino RD crankset is what I'm after, but I can't find it sold just as a chainring.

I'm in the same boat. My LBS can order the Sugino chainring, but it's out of stock. What's worse is that I'm also trying to find the same thing in black to match my black RDs. That is impossible. Luckily, I'm willing to accept either 48t or 52t, so I can find road rings that fit and just ignore the ramps and pins. Actually, I have a black 48t FSA chainring, but I'm still half-heartedly searching for something a little more plain.

I ordered the universal chainring (http://www.danscomp.com/459030.php?cat=PARTS) from danscomp and the 48 tuff neck I got had the cutouts. The 47 was just a flat piece like in the pics and branded rocket, not TN. As with so many things in life, actually calling the retailer gets you a lot farther than teh intrazebs.

Bah. I'd be happy with ANY STYLE, ANY BCD 1/8" 36T chainring. Sadly, they don't seem to exist.

1/8" chain is happy as a clam on 3/32" rings

I didn't think people really argued about this one, it works fine, you just loose a little of the advantage of large engagement area that 1/8" chain has.

TA, Sugino and Rocket Ring all make a 48t, 130bcd, 3/32" ring.

I didn't mean to say there's a war brewing regarding this. What I meant to say is, when I point out that 1/8" 36T chainrings, in any BCD or style, simply don't exist, there's always someone pointing out the obvious and by now very tired point that one can use 3/32" chainrings. Well DUH, but that's not what I want.

What I want doesn't exist.

Thanks, Rattlebag. That is just the type of ring I'm looking for. Now I just have to find a U.S. dealer for them, since I've only found UK and German dealers after a short search.

I also still haven't found a Rocket Ring or Sugino ring with cutouts in 130bcd, 48t, 3/32". I looked around so if someone would like to share a link to a dealer that would be cool. All I've found from those two are solid rings.

No, though probably such chainring exists for those strange BMX cranks. The world of BMX is strange to me, I don't understand any of that stuff - very alien to me. I know that BMX bikes have a larger BB shell, weird cranks, and weird chainrings with an eccentric hole.

So maybe this is a good opportunity to ask: how does one go about using one of those werid BMX chainrings on a bike with a normal BSA BB?
