    If you currently have a medium cage you'll get a 30 on it but not a 32. Either way you'll need a new chain as even a 30 will require more length.

    Do you really need a 32? - there's a bit difference between a 28 and a 30.


    An Ultegra SS (Short cage) will take a 12-30(10 speed), even though 28 max is recommended, with minor B screw adjustment. Some forums discuss using a SRAM 32 by putting in the B screw backwards... dunno about that.

    An Ultegra GS (Medium cage) is for a 32(11s). There is no 11 speed that ends in 30, unless SRAM do one!?

    Note 11-32 (11s) is very "clunky" on the lowest three gears. The RD/chain/crank view isn't the prettiest of things either. not very neat tbh.

    As for your chain... if you add a SRAM/KMC link you might get away with it. you would have to test it (carefully) using the big ring/32 combo though. As long as there is still a slight "S" in the chain going through the RD you are good to go.

    My LBS claimed that the short cage on my Ridley wouldn't take anything more than a 28. I had asked them as I had to take it to the Alps a couple of years ago when my Fuji (which has a medium cage with a 30) let me down at the last minute. Managed fine on the 28 all the same.

    (It's a 10 speed if that makes any difference)

    All I can add is that my 10 speed AL9.0 is running a 12-30 on an Ui2 SS RD
    I doubt it's Ui2 make a difference?

    There was very little B screw adjustment too.

    If the real source of concern is knee pain. I'd look at getting that sorted. Sounds like you got up the hill ok. Maybe try some specific knee strengthening (single leg squats etc) exercises and avoid the steep hills until the legs are stronger. Your cadence won't be much quicker with a 32 or 30 vs a 28.

    Your knees might thank you for it though :D

    I tend to do all my climbing seated and don't find I've any problems with knee pain. Coughing up bits of lung at the top would be more of an issue. :pac:

    At least you last until the top before that happens! :pac:
