Just had a little accident and both of the jockey wheels have ended up getting mixed up and I am not 100% sure which is which.

I think the top JW is the 1 with the metal inner and the bottom 1 has plastic bushes.

Can some1 please clarify this?

LX 9 speed!

    look on the side one says more than the other. I thing G pulley or guide pulley, that is the top one.

  • If you can't read it, or it's worn off, the top one has side to side float on Shimano stuff, so if you hold it all together between your fingers, the jockey wheel will have a couple of mm of movement side to side. The bottom one doesn't.
