Straight Driveline and Chain noise

I recently got an IRO Mark V about 5 days ago, I've put on about 90 miles since. But whats been biting at me is this little shikishikishiki noise on the rear cog. I've looked around the forums and have come upon different threads about this, but still got nothing.

My first question is, How you tell if you have a straight driveline? Do you look through the cog and see the chainline? Are there any techniques you can use to achieve this?

The second one is, I've moved the rear wheel everywhere, ran the chain tight, ran it loose-er, but I have still never been able to overcome that chain noise. It's a brand new cog and chain, so it couldn't be wear. Chain has no stiff spots, etc.

Thank you

Over the winter I replaced my entire drive line, new cranks/chainring/bb, new chain, and new rear cog and always had a slight noise since I installed them which annoyed the hell out of me. Last week I added some oil for the first time to my chain, and the noise completely went away.

There's your problem. New drivetrain stuff is often noisy, especially if it's all 1/8". Lube your chain and keep riding.

Ah, alright. Thank you, this is my first FG, so It had never happened because my old roadie was silent.

I had a similar thing with my IRO, although in my case it was something that I felt more than I heard. I tried tightening and loosening the chain, and also tweaking the chain ring, with no change in results. I even had Tony from IRO on the phone and he acknowledged and was able to reproduce the "noise". From my experience, it gets better with miles, though I've got ~1000 miles on mine and there is still a hint of that vibration. Maybe in another 1000 it will be completely gone...

My personal opinion is that what you are experiencing is due to new, not optimally machined components wearing in. My ultimate message to you is that it will get better. And know that IRO bikes are great products. I've had minimal issues with mine and just love riding it.
