Do the GX ones have a narrow-wide profile?So does it not matter that these are 11t and the GX are 12t?
Yes I think they doDo the GX ones have a narrow-wide profile?
Me neither. I bought the bike like this. The derailleur made grinding noises so I threw another GX I had and it's sweet. The only thing I can find wrong is there seems to a lot of movement in the jockeys. But they have 12T...No idea. The ones I linked to are for 11sp. There are probably 12 speed ones available too.

Could be worth a try.Looks like a standard bearing... Anyone tried to size it up and press in a new one?
