So I'm going to talk about some of the tools we have on the wall here so you're familiar with what they are when you walk into a bike shop.
We'll start at the left here: these are cone wrenches. All different sizes; they go from 13 to 24. Most common ones are 13 and 15: 13 for the front wheel, 15 for the rear wheel. Basically what they do is they fit right inside the hub, inside the lock ring so they're nice and think. Basically they're for adjusting the hub.
All tool for bicycles are usually metric unless you're dealing with something that's kind of old, either like a Schwinn or maybe an old English bike. Everything else is entirely metric.
As we go up here, this is a wheel dishing tool. Basically what this is used for is... you want to make sure that the wheel is dished properly, so basically meaning that the rim is pulled to each side appropriately. So you just kind of place it up there, push it onto the hub. Then check the other side, see if it's dished. So it is. If it wasn't, basically what would happen is there would be either a big gap in between the hub and dishing tool, like that. I mean, that's very drastic. Or it would be teeter-tottering on the hub. So what you would have to do is, you would have to take all the spokes on one side and pull them or push them the other way.
Next is the chain whip. So this is used for taking off cogs or holding a cassette in place so you can remove the lock ring. Then we have, obviously, a hammer. This is a lock ring wrench; so basically this is for bottom brackets or headsets or some wheels, like fixed gear wheels; you'll see it will have a lock ring on it and this is the tool you'd use to take it off. We also have a tool that's called a lock ring plier which basically is a pair of pliers to hold it tight so you don't hurt your knuckles.
Next we have headset wrenches and they go all different sizes. They're nice and thin so they fit on the bottom nut of the headset. Then you can use a regular wrench on top; an adjustable wrench. That's for threaded headsets.
Next we have a pedal wrench. So basically it's a 15 millimeter wrench that's nice and thin so it fits on the pedal, in between the pedal and the actual crank arm. They come in various sizes and different shapes. Down here we have our wire cutters, specifically made for bicycle maintenance. So it's more rounded so when you're cutting the housing, it keeps it round instead of flattening it out like these side cutters would.
Then we have another pretty bike specific tool. This is called a fourth hand tool. What is does is, you put the cable in and then you pull it together and basically what's it's going to do is pull that cable. So that's good for adjusting breaks and adjusting derailleurs; pulling that cable instead of using your hand if you need a little bit extra leverage.
