  • Hi everyone,

    New Shimano CS-HG800-11 cassette goes all the way down to 34t (11-34). Good news for my weak knees, however tech docs also say the new cassette is only compatible with (also new) Ultegra RD-R8000-GS. Any thoughts as to whether the new cassette will work with good ol' 105 RD-5800-GS? Possibly soneone already had an experience? Thank you.

  • There's a possibility it may work.

    If you have 11-32t on your wheel already with the 105 GS, how far have the b-screw gone in?

    If it managed to clear a 32t cassette on the small ring with little adjusting on the b-screw, then try and tighten it further and see how much gap you can obtain between the upper jockey wheel and 32t sprocket.

  • AFAIK it can only take a 28. Its first gen sram road.
    The problem is without a washer the mech moves side to side 4/5mm on the knuckle.
    I'm sorry if my layman's grasp is a bit weak.

    Edit; in hindsight I should read who you replied to. As you were.
