How to change a chain
How to install a new chainring (crankset, chainset or crankring)
How to replace the entire cassette (or cogset)I'll start with explaining the jargon and make it as short as possible using 3 phrases. The chain is the most obvious part, which you should know already. The chain is connected from the cassette to the crankset. On (e.g.) mountainbikes, the chain moves through the back derailleur and along the front derailer as well. That's it. Just think that the chainRING is the part at the pedals and has the form of a ring. The cogset is the part attached to the hub of the backwheel. If you know what a 'cog' really means, then you always know what the cogset is. A gear or cogwheel is a machine part that has cut teeth, or cogs, which mesh with another toothed part to transmit torque or force. In the case of a bicycle, the toothed part engages with the chain. To ensure smooth transmitting of force and to make sure that the tooth of the cassette connects to gap of the chain, the distance between tooth and gap has the be exact match. The derailers are used to push the chain on a smaller or bigger ring or cog, depending which gearshift you use (left or right of the handlebar; front or back derailleur).
Protip: if your chain is worn out, you will probably have to put your chain back on your bicycle every time you shift gears. Reason for this is that a teeth connects with the chain itself in stead of the gaps between the chain pins. It will cause the chain to be pushed off the cassette or chainring, making the chain jump a gear lower or jump of the bicycle altogether.
That is basically how it works and a quick description of what parts are important.

How to maintain your bicycle chain and how to attach/detach a bike chain
How to Lubricate the Chain Correctly
- Step 1: Put your bicycle on a spot where you can afford to get your surroundings a bit dirty
Things you'll need:
- Degreasing detergent or any citrus detergent
- A lube that is suitable for a bike (not automobile oil, household oil that contains vegetable oil or WD-40 and other thin sprays)
- 2 rags and a bucket of water (to thin the degreasing detergent)
- Flathead screwdriver or some thin scraping tool
- Step 2: Tilt your bike in a stable position and start analyzing the parts we've talked about earlier
- Step 3: Clean the derailleur and remove dirt from the cassette/chainring
- Step 4: Clean the chain itself
You start by getting the remaining products ready mentioned in the first step. Take the bucket of water and add a bit of degreasing detergent. Make the a rag wet and wring it out. Go to the tilted bike, wrap the rag around the chain and start pedaling. Just make sure that it is as clean as possible.
