Looking for an online source for rings and cogs. Seems the only thing my LBS carries are the ultra-expensive rings and cogs. Buying them individually, I'll end up with a set of rings and cogs that are worth more than the damn bike?!? Can someone suggest a place to pick up a set?

chainrings are pretty expensive...

There's some kind of deal just above the groups, 2 Sugino rings and a full set of D-A cogs for $185. The best deal you can get unless you work in an LBS.

I assume you're located in the US so https://www.businesscycles.com has a lot of really good stuff. They're not the most competitive on price but it but are a pleasure to deal with.

Chainrings as previous poster has noted are expensive esp properly round 144 bcd ones. But they'll last for ages and you can often recoup a lot of your outlay in the second hand market.

Ebay and Craigslist often pop up some good deals if you know what you're looking for.

I actually found that site last night doing a search for track components. I notice they have:

# FSA
Track 1/8" (black anodized)
45, 46, 47, 48, 49, 50, 51, 52 - $39.50


Is there anything wrong with these rings? Cheapest rings I saw at the LBS were over $90 per ring. This looks like it will be a little easier to swallow.

FSA rings are fine. I'd just suggest that you put any new chainring you get on your crankarms, mount a chain, and be sure the chain tension is pretty consistent throughout the rotation of the crank. It's hard for anybody to ride enough to wear out a 1/8" track chainring, but many of them out of the box do not have perfectly concentric mounting holes so the tooth circle is effectively out of round. If that's the case, return it. If not, they will all do well for you. Dura Ace have a slightly better finish on their current 7710 versions, and Sugino Zen (track, not the black messenger version) are particularly accurate and round, but they are nearly all interchangeable (just be sure you have a 144 BCD) and do the job just fine. Tooth profiles are sometimes slightly different but that's largely a marketing thing and less critical on the chainring anyway -- if your teeth are not optimal to begin with, the chain will take care of that within a month or so.

I built up a good collection of chainrings (mostly campy) and cogs (mostly DA) on ebay.

Just my $.02
