servicing rear derailler pulleys (derailleur)
I have read, watched videos but I am still unclear as to what to do. I have an ultra RerDer, about 2 years old with about 7k miles. I cleaned up my bike and ordered new pulleys over the winter but the new ultra pulleys didn't come pre-lubed, What should I do? In case you were wondering I believe they have ceramic bushings. Do they need grease or oil?
