Okay, sorry to bug you all again. I did search around and I can't' seem to find an answer for this one.

If I'm using a stock iro bb, on a stock iro crankset 3/32 130bcd crankset that came on my iro...if I replace the iro chainring with a eightinch 1/8 130bcd chainring (I have a parts hoarder friend hooking me up with 1/8 chain,cog and lockring) will I run in to any chainline issues?

Can I also use the iro chainring bolts or will I need a new one? Cheers everyone

You should be good.

All right...I hope so...

Chainring bolts can be re-used. Dont see why it would cause chainline issues, but does your crank allow you to mount the chainring on both the inside and outside of the spider? If so by mounting it on the inner side would help with chainline if it becomes a problem.

I'm actually not 100% sure, I emailed iro to see and they are closed for abit while they work on their inventory.

Maybe someone can chime in who owns the same crank, but it should be machined similar to the outer side with a ridge on the inner side of the spider that will sit flush with the chain ring.

See post #2

I did some searching and found out you can mount iro cranks either or, thanks everyone!

Dude, really...put the new chainring in the same place as your old one, using the same bolts. Really.

Why does this stuff have to be so hard?

If your chainline was good to begin with, then put the new chainring in the same position. You will still have the exact same chainline within a mm. Since you are using an IRO crankset and BB, I'm sure your chainline is fine.

Or you could have just looked at your cranks for 2 seconds and come to the same conclusion.

I was at work dude mcdude! Sorry :< I was incorrect my cranks only allow for outside fitment but thanks for your response!

&Scrodzilla - I <3 you

I just ordered my chainring on lunch. Cheers everyone!
