    7 further fields the checker looks for are not published by Race Face, so we leave them blank rather than estimate them, and those 7 checks stay silent on this crankset. They are speeds, chain width, speeds rated, front rings, ring mount as shipped, ring bcd as shipped and ring bolt count as shipped. 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 1833 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.
