Will not fit

  • Will not fiterror · Rear DerailleurSpeed mismatch: Shifter 11s, Derailleur 12s. Shifter, derailleur and cassette must be the same speed count. On 39 of the 75 verified rear derailleurs in this catalog. Applies to all 2 variants.
  • Will not fiterror · CassetteSpeed mismatch: Shifter 11s, Cassette 12s. Shifter, derailleur and cassette must be the same speed count. On 31 of the 60 verified cassettes in this catalog. Applies to all 2 variants.
  • Will not fiterror · Front BrakeShifter mount: Shimano CUES SL-U8000-11IR is a I-Spec II lever-integrated shifter (no bar clamp of its own), and the brake levers take MatchMaker X, so it does not bolt to them. The band-clamp version of the shifter, or a ShiftMount-style adapter, is what bridges that. A shim or adapter may make other sizes or standards work, but that is a modification, not a fit. On 21 of the 92 verified brakes in this catalog. Applies to 1 of 2 variants.

The checker compares the dimensions listed in what we check, and what we don’t. “No conflicts found” means no conflict among those dimensions — not a guarantee that a build works. Errors mean it won’t fit; warnings mean it works but check; infos are notes.

Checked against

The checker ran this model against every verified part below that it has a slot for, the same way it checks a build in the builder. What follows is the verdict it actually produced for that specific pairing — not a recommendation, and not a guarantee any of these parts fits your own bike.

6 of 1874 counterparts with a page of their own that the checker actually probed this model against, in alphabetical order by brand and model — never by price, popularity or the verdict itself.
