    Record 11 12/27 cassettes

    Can one use a short cage with a 12/27 or does one need to go to a medium cage?

    I'm thinking about 11 but all my groups currently are 10s. In 10s, as you know, one has small, medium or large depending on cassette range. I gather from your comment that this is not the case with 11.

    How does 11 handle these differences?

    The short cage RD handles up to a 50/34 crank with a 12-27. That's the maximum wrap they sell, so it handles all needs, since there is no triple crank.

    Campy will soon offer a 12-29 cassette that requires more chain wrap. It's been posted that all the RDs made past a certain time will handle the 12-29, but that does not help those who are owners of older 11 speed RDs. Supposedly older RDs can be updated, but it must require a longer cage length.

    It is simple to modify a 10 speed RD to work with 11 speed.

    C-40, that's exactly what I needed to know especially since I'm using compact cranks.

    Thank you for your timely response, it explains a lot.
