  1. Looks worn. Would normally expect to see more meat on it than in the picture. But if that’s worn so will the chain and the rear cassette probably

  2. Yes it is. Based on what I can see in those pictures, I would be getting a fresh chainring on there.

  3. Your chainring is spent. If you don’t change it, it will accelerate the stretching on your new chain and age your whole system faster. You (probably) will also want to replace your derailleur pulleys. Replacing your chain when it hits the mfg suggested stretch point will help extend the life of your whole drivetrain.

  4. It was worn a long time ago. It is now the ghost of a chainring. Change it along with your chain and cassette to avoid ruining them.

    Yes. Check the chain and cassette too, you’ve probably worn out the chain and 1 or 2 gears on the cassette. You might need to replace everything. You might even need new cranks because some cranksets don’t have removable chainrings, I’m not sure whether yours does or not.

    This is caused by letting the chain get too worn out, when your chain is worn past a certain point it will wear the chainrings down to match (but since you won’t use every gear an equal amount it will wear some gears more than others, which will lead to skipping in some gear combinations which can be dangerous). You can avoid this by checking the wear on your chain and replacing the chain more often. There’s a tool you can get to check the wear and they’re quite cheap or you can get your local bike shop to do it. You also want to clean the chain/gears regularly, and re-lube the chain after cleaning to help your chains last longer.

    I’ve had the same front chain rings on my commuter bike since 2017 and had the same cassette on it for about 8 years before I had to replace it. I’m sure it ends up cheaper in the long run to replace the chain before it’s totally worn out because gears and cassettes are expensive and chains are relatively cheap especially 8 speed. You can potentially keep the same gears on your bike for the entire time you own it if you’re not riding 1000s of miles.

    Looks like it was lubed with abrasive paste. I’d recommend replacing the entire drivetrain based on this alone. And going forward, clean the chain periodically, don’t just add oil. And use a quality chain lube.
