any recommendations for a good track cog? mine has stripped out. also what are the pros/cons to 3/32" as opposed to 1/8"? im guessing its just the different sizes of chains that are compatible with each width?

The threads on the cog stripped or the threads on the hub stripped? Usually it's the hub that strips, in which case another cog isn't going to help.
In any case, EAI and Phil Wood cogs are both fine choices.

Dura Ace all the way

Dura Ace all the way
Especially given the price.

Actually, it might just be easier to say which cogs one should stay away from, as there are plenty of decent cogs out there these days. Also, in reply to the OP, 1/8" vs 3/32" just refers to the physical thickness of the cog teeth. 1/8" is track standard.

Yeah, and don't assume 1/8 is the BMX standard... I goofed on that one. Last night found out I need to buy a new chain (oh well, shouldn't part out my BMX bike for the fixie anyways). Apparently none of my 3 BMXs have 1/8... even the pretty silver/red KMC :(
I usually use EAI cogs, they just seem to last and last. When they didn't have the standard EAI in stock my shop ordered me the "Superstar" version. Just installed it so I can't speak to anything other than it looks good.

at a michaux 50mi XC race i saw a guy racing fixed, he didnt finish because his EAI cog sheered apart. i spoke to him after the race and he said it wasnt the first time it happened! a portion of cog containing 4 or 5 teeth came off in a whole chunk. pretty amazing!
i dont think this would be an issue riding on the street.

i have a surly cog on my bike right now, still have a DA that I've used a little bit, and I've had no-name "crappy" cogs on there... Hard to notice much of a difference.
basically just stay away from any cogs that are stamped from a single piece of flat metal, any whose threads are visibly uneven or don't look well machined, or any whose threaded flange doesn't look as wide as the others. dura-ace is a great cog for the money, but has limited sizing. EAI and phil are fine cogs but a little pricier because they are nicely finished.
personally, I didn't trust the surly cogs when i saw them at the LBS. I've run dura-ace and the Blue Collar (milwaukee) on mine and they're roughly comparable in quality and price.

I've used Campagnolo, Dura-Ace and Suntour, and purely subjectively the Suntours feel fastest. They're hard to find now but I rate them very highly.
Dura-Ace and Campagnolo are about the same.
I'd love to get one of those cogs Tomity makes.
Anyone had any bad experiences with Roselli cogs? I'm running one at the moment.

Suntour. Funnily enough, it is the only cog in stock at my LBS, and I'd rather grab these at next to nothing than order something. Good lockrings as well, included.
