I've had issues with chain skipping for a while now, but looking down on my cassette while cycling, I couldn't identify there being any chain skipping when it does skip. Looking at it today, it seems to be an issue at the rear derailleur where the chain stiffens and protrudes until it resumes motion.
Is it a chain issue or a derailleur issue? I know it is filthy by the way. It is an issue that started since I installed a new freewheel (I have a fairly old school bike with downtube shifters as well).

you have a stiff link.
but holy shit that jockey wheel is fucked to hell.
Based on the state of the pulley wheel I think the drive train needs a lot of work
That jockey wheel is cooked. Whether that’s the cause idk but I’d start by replacing that thing
That jockey wheel is more sharked than an actual sharks tooth.
Time to clean your bike…
That pulley wheel have served his time, get him out there.
Your chain is trash and needs to be replaced as do now your jockey wheels which were probably ruined by your chain. I’m guessing you have done zero maintenance to the bike.
If you are not into maintenance ,then take it to a shop
New bike day !!!
On serious note that chain needs renewing which if also renew the sprockets at same time and give the derailleur a seriously good clean strip the jockey wheels down and clean the etc
It’s because you need new jockey wheels, chain, cassette and probably chain rings. They look like they’ve never been maintained
As my recommendation
Change the both pulley
And chain may helps
Its more likely 30$
Drivetrain is in lack of maintenance self destruct mode. It needs a complete, well, everything.
I’d say the jockey wheel is fine, it’s likely an older model that didn’t have big teeth to begin with. You should however thoroughly clean your drivetrain and chain. Maybe get a new chain even. Do some research on chain wear and when to replace it. Looks like your previous lubricant has attracted a lot of dirt, so maybe change the maintenance routine before getting a new jockey wheel. Hope it works out
This is absolutely prime r/BicyclingCirclejerk territory. Those jockey wheels are horrific.
If your jockey wheel is in that condition then it is guaranteed that chain needed replacement in 1993.
You can get a new chain and jockey wheel but you’ll be back asking why it’s skipping.
Because it’s ready to die. Did you ever change your chain?
holy sh*t. poor bike.
I se only one pulley. One is missing.
New chain, new freewheel, new chainrings, new jockey wheels. A used bike would be cheaper than doing all the repairs at a shop
Did that spinney disc used to have teeth? 🤣🤣
Clean this bike properly, the belt is blocking because of dirt and you have to change the gears that are already worn out.
Seeing this makes me feel better about my own bike maintenance
This is why we keep our bikes clean..not to wag my finger here but, this could have been avoided with even an occasional cleaning/the most basic of maintenance.
You could try cleaning it and such now but uh..yeah, this is a new jockey wheel and chain for me..if not a whole new rear derailleur..call me wasteful lol. I’d be sus of the cassette too. Can’t imagine this being the only thing that needs attention either. Hit up a local bike co-op if you have one nearby..or mom n pop shop, see if you can find parts on the cheap…if this isn’t your thing or you don’t work on bikes, pay the extra money and take it to a shop.
Have you tried kicking it Op? Just boot it a few times homie, you’ll get another 20,000 kms before she needs another booting. Take it somewhere remote with no chance of rescue service and she’ll get you home , what else would you do right?
When was the last time you changed the chain? Ever? The first Bush administration?
