Im happy with the niner cogs, got a season over 1500 miles out of one, 20t is like 18g if i remember right, dont ever think ill run a steel cog again... I run an alum salsa ring up front same deal, get good wear and light weight..

GreenLightGo, that is a beautiful cog. Is it a Boone? What model of chain is that?

Boone Ti - got it from singleandfixed.com. It's very indulgent ($65 bucks), doesn't help me go any faster but all the cool kids had one.:D Actually - got if for my birthday. I'm trying to get a full set (not of the Boones, just a full range of cogs). I've got 16, 18, 19, 20 and the Boone is a 21T. Need a 17T and 22T to fill out my line up. I've got 32, 34 and 36T chainrings. Pretty much have enough spares to get gearing needed for whatever I may want to do.

Chain is a Shimano HG-93 9 speed chain that I used for a while on my Sultan until I broke it one day. Still had enough life left in it and was long enough to use on my SS. Works fine with the Blackspire up front.

I vote for King all the way. I've been running those and Surly stainless rings forever. My old Klein hardtail with Surly 34t and cheap heavy bmx cog weighed in at 16.9lbs. I would rather have that than 16.5lbs and have to replace the cog and chain once to twice a season. Also the Surly chainrings last longer than I could imagine. Mine has about 4000 miles on it and is still kicking on a 1x9 setup. It gets regular SS use all season and then switch to a geared snow bike for the winter. Dual duty year round for about 4 years.

The CK cog I bought last season has about 600 miles on it and looks really good as well.

Well...

I've found it possible to get away with an aluminum cog if it's a larger tooth size. Think about it, your front cogs are aluminum. But, for an 18t cog I'd recommend steel. I'm a huge CK hub fan and their steel cogs are nice, but their aluminum hubs wear very fast.

Niner's aluminum cogs have done me very well and are my favorite cog as long as I stay at 19t or above. Smaller than 19 and they wear too fast.

So if it must be an 18t go with a steel cog, and yes the Kings are good.

Happy hunting.

+1 on Surly!

Niners are too soft, Kings wouldn't fit on my I-9's (too tight to even slide on), had a Boone but it was one with the short teeth issue and would throw the chain every 3 or 4 miles...Surly, please for me!

I used Chris King cogs and had a super annoying issue where the chain would ride up onto the cog then slam back down, on the bike it felt like the chain was skipping. Turns out their suggestion of an 8-speed chain solved it! I had a SRAM EX1 chain (10-speed) which worked fine with the Niner 22t cog but would not work with the CK 22t cog.

Since I last posted I discovered that King cogs, due to their short height are much more prone to jumping a chain.

Since then I've moved over to Surly cogs. They are steel and have very tall teeth which prevents chain jump.

I have CK (18T and 20T), a Surly (17T) and an Endless (16T). The CK and Endless are lighter than the surly. The CK and Endless teeth are centered on the Cog while the Surly is offset. Not sure what kind of spacers/hub you run but they may need to change a bit to get your chain line right. Between Niner and CK, Id go CK all day errry day.
