Hi there,

I just bought a Sugino Chainring:





and a SRAM chain:



They don't fit. It's as if the chain is too small. Any ideas why? I've used these chains before, and they fit the stock Truvativ Omnium chainring as well as the Sugino Messenger chainrings.

If you bought that chain used maybe a 3/32'' chain was placed in there by mistake.

Idk but your pics are sweet.

Let's see a picture of the chain not fitting.

Is this for a Pista? I had the same problem. If it is the pista, they come stock with 3/32 parts so if you switched up to 1/8 you need a 1/8 inch chain as well. I know everyone says they are interchangeable, but in my experience, the chain didnt quite fit, when I went to put pressure on the pedal, it made a clicking noise because the chain was not seating on the cog quite right. Use all 1/8 stuff (chainring, chain and cog) and you wont have a problem

thats actually a 5/32 chainring.

so the packaging is wrong**********?

well, here is a 1/8" chainring fitting:


clearly a 1/8" chainring:


not fitting:

Yes it is. It also says that the chainring is "black" when it clearly is not.

I don't know brah. I would be a little more respectful in tone to those who have been here a lot longer than you. Especially when you post things like asking for "street style" clipless shoes for riding around town with your friends.

^ Did you compare penis sizes, yet?

What are the labels on the sides of the plates?

Nah.

For what it's worth, my PC-1 definitely doesn't have the fluted inner links.

No such thing and this would be a good opportunity(and thread) to beg people not to post technical info if they don't have a clue what they are talking about.

This thread really needs one.

the chain seems to fit around the teeth, it's as if the pitch is too large.

*hint* i think it was a joke...

A 1/8 chain will fit on a 3/32 chain ring and a 1/8 chainring but a 3/32 chain will not fit on a 1/8 chainring.

Your chain is 3/32.

Check it against a chain you know is 1/8th

3/32 chain on 1/8 chainring. Case closed.

now post some more photos, you have mad camera skills.

Wait...the chain fit on the other 1/8th chainring.

I second the 5/8th chainring idea.

Priceless...

Not quite, check out the photos again.

Something fishy's going on here. A borked chainring maybe?

Okay, here's the deal:
According to the OPs photos, there shouldn't be a problem, whether or not the chainring is 3/32 or 1/8(the only two options for modern rings) the chain box he shows indicates the correct pitch(all modern chains/chainrings are 1/2" pitch) and width to fit either 3/32 0r 1/8.
This thread is most likely attributed to a "brain fart" by the OP, happens to all of us.

BTW 5/8 is over half an inch, kinda thick for a chainring, don't ya think...

OP is messing with everyone. Maybe he wanted to see what kind of crap people would spew?

If so, he succeeded, crap has been spewed. I'm giving the benefit of the doubt, we all make things too complicated at times. Throw in a bunch of misinformation from some guys I wouldn't let change my bar tape and things get really convoluted...

wait, what is confusing here? The pics are pretty clear what the issue is.

I have a chain that is clearly 1/2" x1/8", evidenced by box and the fact that it fits another chainring that is labeled as 1/8" width.

The chainring in question, is supposedly 1/2" x 1/8", but the confirmed 1/2"x 1/8" chain does not fit it. Does anyone else own this chainring? Can anyone tell me what is going on with it?

I am not trying to confuse anyone, as I am thoroughly confused by this matter. Supposedly all chains/chainrings have 1/2" pitch, okay. So why doesn't my chain fit? This Sugino chainring is making me sad.
