not long ago my shifting started making a grating noise I looked down at my derailleur and saw that the cage was bent forcing the chain to rub against the metal.
Any advice is welcome.
Thanks for the help Oscar.

    I don't have any particular advice about how you might straighten the cage and it's not clear how badly and what bit is bent... photo? And whether it's worth trying to straighten.
    However, finding a NX 12 is near on impossible at the moment. Nobody has stock.
    I blew up my SX12 yesterday - forest debris - and was going to replace the SX with NX (as the SX is pretty much rubbish) but couldn't find any.
    I am going to replace it with a Shimano SLX 12 which, as with the other Shimano12 range will work fine on a SRAM setup.

    Is the derailleur bent or the rear hanger?

    If the latter, you can buy a straightening tool.

    or just buy a new rear hanger for a tenner and mess around with buying tools he won't know how to use.
    .
    The camera down the willy isn't anything like as bad as it sounds.
