I stopped into my LBS today asking for 17t cogs and they offered to sell me a "Brewtal" cog for $40. It seemed to be a solid alloy cog and it was the mid quality in their selection. They had some Origin8 and even an EAI Gold. I didn't end up buying it, then I was curious so I looked up Brewtal but couldn't find anything. So can anyone tell me if they've had any experience with the brand?

Thanks
