Great simplicity in explanations of both removal/install process and part identification. Could use "close-up" camera shots to visually clarify emphasis of the demonstration (i.e. "fat tooth"). Other than the needed close view camera shot, the demo was superb!

How to Install a Bicycle Gear Cassette

Hello, this is Russ from the Salt Lake City Bicycle Collective, online at slcbikecollective.org, and today I'm going to show you how to remove cassette from your rear wheel. First thing you're going to want to do is take the quick release out. Make sure that you don't lose the spring; we'll need it for reinstallation. The next two tools that you're going to need are going to be bike specific tools. If you were in Salt Lake City, you can come down and use ours during open shop night, otherwise you're going to need to go to a bike shop and probably pick these tools up. One of them is the chain whip and this is going to keep the cassette in place from moving while you're trying to remove it. The other one is the cassette tool here which is going to engage into this and allow you to turn that piece off of there. You're going to take a crescent wrench with this tool and go ahead and turn it counter-clockwise which will remove it. It may take some force, sometimes you'll need to put it on the ground. Once you break that one loose, you'll be able to spin the rest of it off by hand. You're going to thread that piece off, you don't need the chain whip anymore and to remove this, you want to make sure you keep everything intact. Often, these gears are separated sometimes by spacers or washers. So you want to make sure they go in there in particular order and you don't lose them. And for reinstallation, they go back in with the, there's always one fat tooth, so you want to make sure that the fat one lines up on the cassette where it needs to go and you're going to slide that back on there. Put things back on in the original order and go ahead and tighten it back down.
