New jockey wheels causing chain rub ?

[geetee61]

Hi all , need some advice please. Been running XT M770 groupset on the VitaminT T now for the last 8 years or so with no problems at all. Today I changed the jockey wheels on the rear mech and fitted a pair of Hope orange jockeys to add a touch of colour. Now I’ve got the chain rubbing on the rear triangle when I’m on the large front ring and in top gear. I’m assuming the new hopes are too narrow. What do you think. Cheers, Gaz.
