Hi all ,it's been a while since I posted on here but was wondering if anyone has had the following issue? Riding yesterday and it stopped shifting into the large 12 speed ring , had a look today and the top jockey wheel was too close to the cassette. Adjusted the b screw and its now shifting ok. Going out for ride now so we'll see! I have never had to readjust a b screw before after original setup!! Cheers.

    B screw should be set and forget, so, (I'm guessing here) you've had a knock and slightly bent the hanger or derailleur so the b screw adjustment compensates for that, or the springs in the derailleur are a bit tired.

    Ok after adjusting but I'll make sure its not unscrewing or anything . Could have had a knock , I'll see how it goes. Cheers.

    Probably spring weakening.
