The lower one, yes, definitely! They aren’t supposed to be spikey, meaning, they’re totally worn up.

I mean soon the lower one will be so smooth it would have to save you a bunch of watts. Keep running it.

Yes it was time. Probably 5 years ago…

in the end its a combination of skipping teeth, chain wear and general drive train wear. Whoever rode the bike with the lower wheel doesnt seem to clean the drivetrain too often so wear isnt a strong concern.
That leaves skipping, if that became annoying then yes, it was time to replace it.
I would like to see the rest of the drivetrain.
Also, chain cleaning can be described as a three step process, just in case the bike owner wants to try it out:
– remove chunks mechanically and clean chemically (chain cleaner of some sort)
– remove cleaning agend and dry drivetrain
– oil chain and remove exess oil

Yeah the bottom one has been a jockey wheel too long

Not yet. When it converts to a disc you can start to look for replacement parts.

Yeah probably
The upper one doesn’t look that bad though.
