it works as advertised

I've used it several times

Every couple years I get the yearning to punish myself singlespeeding...its that time again. Found my surly spacer kit (needed to take up unused space on freehub body) but can't find my surly 18t cog (probably loaned it out???). Set up easily and has working fine so far (couple rides). Ultimately deducting a star since the price is more than a Surly or Wheels brand cog and I'm not sure I'll ever discern what benefit (if any) the Niner cog has over them. If you want to make an old trail new again and understand the value of momentum over obstacles, trade out your gears for the simplicity of a singlespeed setup.

Light as Ballz

This is my third niner cogalicious cog and I love it. I have several of the tooth sizes in my quiver as to work in different areas of riding. Best value for a cog by far.
