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 5997 verified mountain bike parts in this catalog. 5690 produced no finding of any kind; that is TR-45 203mm (CL). TR-45 180mm (CL) clears 5648. Each variant produces 12 to 112 distinct errors and 6 to 9 distinct warnings.

Check before you buy

  • Check before you buywarning · ForkFront rotor: 203mm exceeds the fork max of 180mm. A post-mount adapter is the part that steps a caliper up to a bigger rotor, sold in the maker’s own discrete size steps (commonly +20mm, e.g. 160 to 180mm or 180 to 200mm) rather than for any gap - and not every step is offered for every caliper model, so check the maker’s own fitment before buying. On 31 of the 490 verified forks 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 1861 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.
