Tooth Chainring

What Can Go Wrong with the Bike Chain ?
The chain is completely exposed at the bottom of your bike, so it easily picks up dirt and grime, twigs and leaves can get caught in it, and it can be impacted with foreign objects (especially if you're riding off-road) — all of which can undermine the chain's integrity and lead to a break at the most inopportune time.
There are a number of telltale signs that you have an issue with your chain:
You have to exaggerate the movement of your shifter to force the chain to jump to another cog on the rear wheel.
The pedal jerks forward when you're applying pressure, because the chain skipped a tooth on a cog.
Pedaling is not as smooth as it once was.
The chain makes a lot of noise while you pedal but not while you coast.
Issues with your chain can be caused by a number of factors. The most common of them are dirt, stiff links, and normal wear and tear.
Getting down and dirty
The chain is one of the parts of your bike that's completely exposed to the elements. This, combined with the fact that it has to be covered in lubrication to work properly, makes the chain a magnet for dirt and grime. The abrasive qualities of dirt begin to wear down the chain and the other parts that the chain comes in contact with, such as the cogs, chainrings, and rear derailleur pulley wheels. When dirt works its way into the chain links, they become stiff, which hampers your bike's shifting ability .
Stuck in a rut: Stiff links
If you find that your chain is skipping or making a consistent, repetitive noise when you're pedaling, you may have a stiff link.
Wear and tear
Although keeping your chain clean and lubricated will greatly extend its life, normal use of the chain will eventually lead to wear. The chain does most of the work, transferring power to the rear wheel, revolution after revolution. After you've traveled enough miles, it begins to stretch, and after it starts stretching, it can rapidly wear out the chainrings and cogs. A stretched chain is also more vulnerable to breaking. Stretching doesn't mean that the chain links have increased in size. It just means that, over time, the wear on the rivets, rollers, and inner links increases the amount of play at each link. The accumulated looseness across many links causes a stretching effect.
