Oiling pivot points?

I'm surprised to see this because I've always been told that WD-40 is the wrong type of oil for bicycle chains, and that it will ruin the chain. There is a lot of conflicting advice out there. I do what my bike mechanic says because I'm not interested in becoming an expert on chain oil!

i kinda thought that the mention of WD-40 would be confusing. a lot of people use it as oil. its meant as a degreaser.


many jockey wheels don't have bearings. just a little washer that has curved edges and those ride in the groves of the jockey wheel. its good to grease the inside when doing occasional maintenance and oil the outside when cleaning the chain.

i mentioned chain because it is intimately involved. sorry sometimes i am too full of info.

Oh, thanks for the clarification. That makes more sense.

That "washer" - together with the rubber parts - is actually the dust seal. It's present in the jockey wheels on my bikes whether they have bearings or ceramic bushings inside. Essentially, it's a simple labyrinth seal, so a drop of oil now and then will help maintain the seal.
