In this video, we learn how to install a cog cluster/cassette on a wheel. Find the wider gap and wider spine and line them up. Then, slide the cassette down onto these. After this, you will have to install all of the clusters onto the top of it. If you need to, install spacers as well so your wheel doesn't get messed up. Make sure you use grease to install the cluster and cassette so your wheel doesn't squeak and they go on easily. When you are finished, take your bike out for a spin and enjoy riding it!
