    Not quite as simple as that sadly (bloody Shimano!)

    Medium can deal with 35T overall difference iirc, and long cage up to 45T. Which means, in practice with a 24/38 up front, you’d be limited to an 11-32 cassette. If you wanted to run an 11-36 as most people do, you’re limited to a 10TH difference up front for a medium cage mech.

    However… On a hardtail, so no suspension movement to compensate for, I ran 24/36 and an 11-36 with a medium cage XT with no issues at all, giving a 37T difference. I’d only recommend this on a HT though, and even then couldn’t guarantee it will be ok on your exact combo.


    That sounds very complicated. I just went for the old ‘triple ring-long cage, double ring-medium cage. Seems to work fine for me.


    If you plan on using a 11-36 cassette you will need the long cage.


    As Zelak says.


    Running 38/24 11-36 with medium cage on my HT with no issues.

    Medium or long cage? Assume medium



    So I have just fitted 38/24 up front, to go with my 11-36 cassette. Does this mean my SLX medium cage clutch mech needs replacing with a long cage?
