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.
