I have campag 11-speed chorus and want to change my 12-27 for 12-29. What, if any, fettling will be needed ? Thanks

    Might need to adjust the derailler a tad, maybe the b-screw will need a twist or two....Nothing major

    By the book, you may need to add a couple of chain links back in too, if your existing chain is sized to the minimum length needed for your 27 setup.

    A couple of chainlinks should indeed be enough. I've done this on 10 speed (12-25 to13-29) and managed with nothing more than the extra links. Which is handy as I only occasionally use the 29 cassette so not having to faff around with the b screw is nice!
