What the checker says52will not fit

Run variant by variant through the mountain bike builder’s own engine. Every sentence below is the checker’s, unedited. Nothing here says this part fits your bike; it says what it does and does not fit among the parts we hold.

Checked against 6050 verified mountain bike parts in this catalog. 5654 produced no finding of any kind.

Will not fit

  • Will not fiterror · FrameRear axle mismatch: Frame is Boost 148x12 but Rear wheel hub is SuperBoost 157x12. On 228 of the 258 verified frames in this catalog.
  • Will not fiterror · Rear RotorRear rotor: a 6-bolt rotor does not mount on a Center Lock rear hub as it is - the two use different rotor interfaces. The part that bridges them is a Center Lock adapter, and the ones makers publish fit one-piece rotors only. A shim or adapter may make other sizes or standards work, but that is a modification, not a fit. On 112 of the 177 verified rotors in this catalog.

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 1879 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.
