    Been running the stainless version since March or so. Very light and sweet looking. No problems whatsoever, but of course I am a lightweight.

    I met the guy that makes em a couple months back. Really nice guy and he let me check out his stuff. Definitely looks legit. I told him if he made aluminum ones I would buy a couple.

    If I diddnt get the Surly Cogs for cost it would be with JBC or Homebrewed all the time.

    I prefer the tooth profile on HBC sprockets. Those look a little pointy.
    I see hills.

    I want to climb them.

    Tomicogs look the same way and function just fine. The teeth are longer and ultimately come to a point instead of a shorter square shape.

    Yes they are labeled as "one direction"but I wouldnt be weary about running them backwards. But who knows. I also hate walking out of the trail...

    I've been using a 20t one on my bike with a 34t chainring since the spring. I took a look at the condition of the cog and looks like minimal wear. I ride my SS about once a week since the install so I can't say it's a true long term test of the cog.

    I experienced the same thing when I initially installed it. After the first ride, I readjusted the chainline via the hub spacers and all is well. A couple millimeters to the side make a helluva difference in the chain and cog playing nice.

    I have a 20T as well. I haven't used it a lot but I did complete a 50 km race with it. No problems so far. Shipped to Canada quickly, and when I emailed with a question I received a very quick response.
