I'm looking for a place to get relatively inexpensive 104bcd (4 bolt) chainrings. I'm looking for rings in the 34-38 range. Odd size rings would be nice but if they are at a premium, then forget it.

I have/want to run two-speed on my "Single" because the way home requires a <50 inch gear. No, I'm not a weakling, I've been climbing this for over a year. And my current set up (32x18, 46.1") is pathetically slow on flats.

I'm looking to run 32x18 and 36x12, or 34x18 and 38x16. I can take up to a 2 tooth slack.

Thanks
