Jockey wheels starting to get spiky. Replace wheels or mech?

I have a 105 rear mech. The jockey wheels are starting to get a bit spiky (only the odd one so far but I know that means they need replacing).

Question is - do I replace only the jockey wheels, or do I replace the rear mech?

If I do replace the jockey wheels, can anyone recommend some good ones to get?

If replacing the rear mech is the only way to go, would I see any difference between a 105 and ultegra rear mech?

  • Merlin do them for about £8. Five minute job and only needs an allen key. Plenty of videos on YouTube.

    Replace jockey wheels only...why spend more than you need to. Likewise Shimano jockey wheels are fine, no need to spend more on ceramic bearings and anodising etc....

    Tacx wheels are far better than original and cheap.

    Don't replace them because of the way they look, replace them when they are having an effect on gearing.
