Hey everyone

I am building my first bike and I was wondering what kind of cog i should get.

I was looking at Surly, EAI, Dura Ace but I also stumble upon this Miche cog which has this carrier system where you don't have to thread/unthread to install a new cog on. I thought it was cool. Has anybody used this cog system before?

Or do you think I should just go with a Surly, EAI, or Dura Ace. I am looking to buy a 17t cog.

Yes, I and several others here have used them, and they work fine. Do some searching, and you'll find numerous other threads discussing the Miche system.

thanks for the input. sorry its pretty early in the morning i didnt think about using the search button. i usually do

I have 2 fixed gear bikes both using the miche setup and I have no plans to ever switch.

compelling. I'd thought about this carrier system for my new wheelset.

hmmmmmmmmmm

Good to know. I am building up a new Miche component bike and will be getting the Miche track cog and holder. Will start with the 16t and move my way around larger sizes if need be

I've been using the Miche system for a few years on one bike along with more typical thread-on cogs on other bikes. Heres my take on it.

1. If you do lots of skidding or forceful backpedaling, I wouldn't recommend the Miche system because their is a chance that the minor amount of back-and-forth play will loosen the lockring. I'm not saying that it will happen, but it might. I have noticed slight loosening of the lockring over time...but very very minor amounts; however I don't skid or forcefully backpedal much with my Miche equiped bike.
2. If you ride a lot of miles, or put your DT through gritty nasty conditions often, the Miche system is more cost effective because the cogs are cheaper and can withstand more wear. By that I mean that when one side of the teeth are worn, you can flip the cog around and use the other side.
3. The Miche system is obviously most beneficial if you change gear ratios often...like at the track.
4. If you are basically a normal person who doesn't ride excessive numbers of miles, doesn't change gear ratios often, and uses a front brake, the Miche system has no real benefits IMO.

I've used it for about a year and a half. I put around 150-200 miles a week on the bike that I have the system on, brakeless, and year round. I skid plenty, and have yet to have any issues whatsoever. If you want to have a nice mix of cogs, it ends up being cheaper in the long run.

I got mine on my bike and am digging it so far. After I got the lockring secured nothing was moving anywhere. I might put it on my next bike build too. The price is a big factor and switching gear ratios is so much easier now.

I was looking at the cog holder online and was wondering... What do you use to tighten it? Can you just use the lockring tool?

You use the cog to tighten the carrier. Once you get it snug tight by hand, you can screw on the lockring to keep the cog from falling off and use a chainwhip on the cog to get it tight. I used red loctite on the carrier, because I never expect to remove it.

Miche makes a very nice tool that goes with the system to tighten both carrier and lockring. Super easy to use, never slips, cheap and eliminates all other nonsense.

I have a Miche cog on one bike, Campy on another, Phil on a 3rd, and DA on the 4th. When properly aligned, the Miche is as silent and reliable as any of the others have been, which is to say flawless. Changing Miche cogs with the Miche tool is so easy and fast, though. Take your pick of cogs. I personally have no preference among them. They all work reliably when installed correctly.
