    Yes. Mind they're different upper and lower sizes though.

    Pottart242.

    What do you mean about different upper and lower sizes?

    So the upper jockey wheel has longer teeth than the lower - I think upper is for better retention, and the lower is for guidance. If you buy OEM ones you'll get one of each.

    ^ This is correct, the lower wheel is marked 'T-PULLEY' (tension pulley) and has direction arrows. The upper wheel is 'G-PULLEY' (guide pulley) and also has direction arrows.

    Hi.

    Thanks for the information but was aware of the difference in the jockey wheels.

    So the answer to my original quest is that will Ultegra 8000 jockey wheels will fit my Dura Ace 9000 rear mech?

    Cheers
