Great Mountain Bike single speed COG.;

Lighter than my Kickass Cog and Absolute Black Cogs.
For durability time will tell but no issues running a 10speed xtr chain I can see how someone commented that their chain was eating the cog... use an appropriate chain and you will be fine (11 or 10 spd).

Final Note: Has a mm or two larger stance so it doesn't chew into the freehub. Great Price and Great Cog!;

I bought this for my 29 inch GT Pro Performer cruiser. I really don't like the stock gearing on the cruisers (I have a Big Ripper and the Pro Performer) so I decided to change to the 22 tooth cog and gear down. I am very happy with it and it looks great. I do wish they had the blue color in the 22 tooth but I am very pleased so far!;

Fits well. Nice and light. However after only 2 rides I noticed the chain had dug into the tooth valley. I was mashing up a few climbs but isn't this what its intended for?;

A quality and (extraordinarily) light weight SS cog. This is certainly worth the money. Niagara Cycle Works delivered the package ahead of schedule and exactly as advertised. Packaging was professional and no defects on the product.;
