Good enough for me. Generic cog. Fits and works properly.

Metal on this one likely to rust.

Good for low end build as a money saver, or while you are experimenting with what final size you want to use.

Number of teeth not stamped in it. No biggie except every time you look through your cogs to find x teeth you'll have to count the teeth.

I've not owned any high dollar cogs in my life but to me I can't see a cog having that big of an influence on your riding.

This one does exactly what you expect. No more, no less. It was easy to put on if you use the rotofix method and a lock ring tool. I'm pretty sure it's made me awesome at riding now too :)

Very simple, very cheap, does the job.
Don't forget that for a fixed gear bike, you need a lock ring too!

I picked up Avenir's 17T fixed cog for the fixed/free build I have undertaken on my 2012 SE Draft. Mated it to a Formula TH-51 32H flip/flop hub (Shimano 17T free on the other side) and locked it down w/ one of Avenir's lockrings. Now, just waiting for the Deep V rim to arrive and I can take these to the street/track or anywhere.

If your building a fixed gear or flip/flop, and want a well made cog, check out Avenir's items, I did, and I am a happy customer! :)

I got this to put on my new single speed with a flip flop hub in the interest of trying out fixed gear riding. I rode my bike with this cog for not quite a full year and for around 400 miles. While it's still got life in it, there is considerable wear. The chain was new and I have kept it properly lubricated, but I will probably go for a higher tier cog the next time around.

These would be great if you wanted a couple to try out different ratios or if you only want that ratio for a couple rides (like if you bring your bike along on a vacation to a place flatter or more hilly than you're used to).

I bought two different sized cogs for my messenger. They have both held up well and performed without fail. They're locked on with dura-ace lock ring. From what I've read, the lock ring > cog when considering build. That said, the Avenir cog and dura-ace ring are keeping me pedaling smoothly.

i wouldn't go with this. it was too short, so the lockring didn't hold it firmly. as a result, it kept slipping. also, because it was too short, it didn't line up with my chain perfectly, which couldn't have been good for it. i ended up spending $30 + $10 for surly cog and lockring, and it's actually not worrisome to ride.

if you've got a shim that would work, it might be okay.

I've only had my chain derail once while using this cog, but that was a combination of a very used, warped chainring, and loose chain tension. Other than that, I've had no problems with it.
