    The rest of what the maker states1 not published

    1 further field the checker looks for is not published by SDG, so we leave it blank rather than estimate it, and that check stays silent on this dropper post. It is cable pull. Each is recorded as “not stated by the maker (not checked)”.

    Source: each variant links the maker’s own page in the table above. Last checked 2026-07-16 to 2026-09-20.

    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 1858 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.
