What the checker says28will not fit

Run variant by variant through the e-MTB 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 495 verified e-MTB parts in this catalog. 488 produced no finding of any kind; that is Fall Line 31.6 / 150mm (INLINE). Fall Line 30.9 / 125mm (INLINE) clears 481. Each variant produces 7 to 14 distinct errors and 0 distinct warnings.

    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 267 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.
