Check before you buy

  • Check before you buywarning · Front RotorFront 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.

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.

The rest of what the maker states4 not published

4 further fields the checker looks for are not published by Giant, so we leave them blank rather than estimate them, and those 4 checks stay silent on this fork. They are minimum front rotor, maximum tire, maximum tire mm and maximum tire basis. Each is recorded as “not stated by the maker (not checked)”.

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 1831 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.
