I would like to know whether I can use a 11-23 11-speed shimano cassette with the RD-R8000 11-speed Ultegra Shadow Rear Derailleur (short cage).
I ask this question because I see the new 11-speed shimano cassettes no longer come in a 11-23 gearing.
Looking forward to your comments.
Thanks

          Probably you'll be just fine, although it's technically outside the spec'd range.



          Per the Shimano 2019-2020 Products compatibility Information document (warning: PDF link), the RD-R8000 rear derailleur is compatible with all of the following cassettes:



          CS-R9100
          CS-9000
          CS-6800
          CS-5800
          CS-R8000
          CS-HG800-11
          CS-R7000
          CS-HG700-11


          As far as I know, that covers all of Shimano's 11-speed road cassettes, and I'm assuming Shimano doesn't produce an 11-23 MTB cassette.



          BUT



          The RD-R8000 is spec'd as



           RD-R8000-SS
          (25T≤CS Low gear≤30T)


          (the GS is similary spec'd with a 28T minimum)



          so a 23-tooth sprocket would be slightly too small per Shimano's specs.



          But it should work for you as Shimano's spec's are notoriously tight - and I already do have an 11-23 on a bike with an RD-8000-SS and it works fine with an 11-23. (I didn't even know it wasn't "in spec"...)



          (It'd be nice if someone could extract the proper image from the PDF...)
