 Welcome to Purefix TV. I'm Amanda and today it's time for anatomy class. Bike anatomy class. You ever have a problem with that spinning thing that looks like a ninja star? Or maybe there's a funny sound coming from the hole the petals go into. It's tough to talk about your bike if you don't know the names of the parts. So we're gonna help you out with that today. Let's start with the frame. It's made up of the top tube, the head tube, the down tube and the seat tube. That's a lot of tubes, dude. In the front of the bike you'll find the headset that connects the fork to the frame and allows you to steer. The stem extends off this and connects with the handlebars. But you knew that one, right? How about another easy one? Up top you'll find the saddle or the seat connected by the seat post. Easy. Down below is the crank set. This is the power plant of the bike and includes the crank arms and the pedals. This is connected to the chain ring, one of the most important components of the bike. Following the chain back is the rear sprocket or the cog. Alright, I hope you guys got all that. Your front and rear wheels are called your wheel set. There are built-around hubs that contain bearings that make your wheels spin and these are connected to the rim by the spokes. Finally, when you skid to a stop, you're burning rubber from your tires. So those are the main components of a fixed-gear bike. Now you can go into any bike store and sound like an expert. Kinda. Check us out next week on PureFixTV.com and stop by our Facebook page when you have a minute. Until next time I'm Amanda and I'll see you in the streets.
