My CX bike lunched some jockey wheels in the mud last week, so I’ve bought a new set of trusty old Hope ones which I have had some success with in the past.

My 105 level rear mech seems a bit unhappy about this though: using the usual 11 tooth Hope jockey wheels, the top wheel fits fine, but I can’t even get the bottom one installed – it seems too thick and so the bolt won’t screw in.

Has anyone else had this issue? Are 11 speed jockey wheels thinner?

How old (stretched) is your chain?

Sorted it the other day. Turns out I have one jockey wheel bolt which is just long enough (the other 3 Shimano bolts I have were too short) 🙄
