Hi folks, I am lubricating my bike for the first spring commute and found this.
Wondering how should I fix it? More specifically, do I need to break the chain to fix this?
Thank you!

Just get new jockey wheels and replace them. They unscrew with the Allen key bolt that serves as the axle too.
take it apart and put it back together with a new jockey wheel. it is very easy to do – and you can leave the chain where it is. if you take it off the chainring (front) you’ll give yourself plenty of slack. [here’s a you tube for you.](https://youtu.be/4Ex0-PRwAtY?si=dHXOuMDEOo2K6GZr)
You won’t need to break the chain, but you will need to carefully disassemble the pulley and properly clean and re-lubricate the bearing (if there is one).
Most shops sell standalone pulleys to do this.
From personal experience, I’ve ridden hundreds of miles on a broken pulley, and you likely have as well. It definitely should be replaced, but it’s not urgent like a cracked frame.
Just be careful loosening that bolt given the age of what you have, as it may be easy to strip.
These are wear items anyway. Poor shifting performance often traces to dead jockey wheels.

Just buy a new set of jockey wheels.
Be aware that they may look alike but they’re not identical. One of them is the tension wheel, goes on the bottom, and the other is the guide wheel. They should be marked.
Buy a new jockey wheel. They can be found (easily, depending on the brand) and generic ones are readily available. See other posts for the specific differences you need to be aware of.
Correct comments aside I’m curious how long this would keep working lol
*shrugs* you buy a new cog…
