To achieve the chain alignment I wanted required some shims I fabricated from thin aluminum. Taht commented should not be considered negative. Rather, it is fact-of-life when when modifying any product. Aside from lowering the gear ration, my goal, I found the wolf ran smother without clunky noise.

Cumple su cometido. El precio algo elevado pero compensa si ahorra tener que comprar un nuevo buje trasero

Love these cogs on my SS mountain bike. Lightweight, durable, cost effective, and not to mention good looking.

I bought this cog for my single speed conversion on a Klein Rascal. I originally had purchased a cheaper single speed conversion kit however the cog would not even fit on the freehub body. I doubt it would have lasted long considering that anyway. While this option from Wolf Tooth Components is a lot more expensive than many others the quality makes it well worth the price.Installation of this cog was very easy however you will need spacers if using it with a traditional freehub body. It is also not only high quality but also beautiful. This is CNC machined which makes for a very lightweight and strong components as well as has a very nice and durable black finish. I have been riding with this cog for a couple of months now and it still looks and works like it was brand new. There is also absolutely no wear on the teeth which you will often see very quickly on cheaper products.Overall if you looking to a single speed conversion on an expensive bike there really is no competition for this offering from Wolf Tooth.

Excellent craftsmanship, but after a few hundred miles there is already significant wear. Go for a stainless cog for better life. Endless and Surly are great options.

The Wolf cog is great. The machining is high quality. The teeth are centered on the cog. No teeth offset for greater adjustment. I used it on a BMX Shimano standard cassette. Great lightweight option for BMX. The teeth are tall to keep the chain from coming off.
