11-32 Casette?

So I have a Giant TCR Advanced 1 Disc, it has a Shimano 105 11-28 tooth cassette. I'm thinking of getting new wheels and am wandering if I can also add a 11-32 cassette instead of the 11-28 tooth one?

Anyone in the know?

    If you have a long cage on the rear then you won’t have a problem. Short cage won’t work.

    Is there an easy way to find out what mech it is? The Giant website just refers to it as an Ultegra shifter:

    EDIT:
    Nevermind, just called the giant store and its a short cage mech. Thanks for the help.

    Doubt he'll have enough chain wrap for an 11-32 with a short-cage RD.

    A new 105 GS rear mech only costs a bit over £30 . Why try to bodge the job?

    You can get away with it without changing the rear derailleur. Adjust the b screw and avoid extreme cross chaining

    Bodge? Have a look at the new Shimano rear mechs, exactly the same as a roadlnk.

    11-32 might be pushing it on a short cage but you can definitely run an 11-30.

    Even with adjustments, I think your chain tension will make things very clunky. As said previously, get a long cage for £30 and you will can get up to 36 on the back (have tried it and it works quite smoothly and currently have a 34 with no issues) giving you options should you ever need them. I certainly did last year in the alps. Certainly wasn’t climbing fast, but climbed everything without having to walk.

    Thanks for the pointers folks. It seems like a faff so I might just stick with the 11-28 and get my climbing better the hard way.

    I'm was running a short cage rear sora derailleur and a 11-32 no problems - didn't even need to adjust the b screw although I know a have read that many do this. Just need to make sure the chain is long enough too.

    The roadlink type bit is an integral part of the R8000 rear mech. design. The OPs mech. was never intended to be used with a roadlink and doing so is a bodge. It will probably work but I see no advantage in using one.

    I've popped an 11 - 32 onto a 2017 TCR advanced. It's working fine with no other changes. My only reservation is don't go big big as the chain is too short. Every other combination is working fine so far after 100 miles.
