This video goes over how to install a Wolf Tooth Components Cassette Cog. As mentioned in the video they are competitors with OneUp Components. One up calls their product a sprocket instead of cog. Which makes me not feel so bad about calling it a chain ring for the entire video. Ok, that was a stretch. Either way, bottom line is this video goes over installing one of them on your bike. I also touch base on why I made the changes in my drive train from 3×9 > 2×9 > 1×10.
