I have long felt like I needed to put some lube in the center of the top derailuer pulley, best it cut down a lot on the friction I felt. But it is hard to do and attracts more dirt. I was looking to maybe get some new pulleys that are fully sealed, top and bottom, to replace my rival ones. I don't know if the whole ceramic bearing thing is worth it but I seems like all the nice after market pulleys are the ceramic type. Does anyone have any recomendations?

Be aware the Shimano RD's typically use a floating upper pulley.
That requires a bushing.

Do the Sram ones I have now rotate on bushings? About the only thing I can find to replace them with would be enduro.
