Marin Frame

2 models, 3 verified variants. Only rows checked against Marin’s own page are listed.

A value shown as a set or a range differs between this model’s variants and is never one variant’s spec. A cell marked not stated is a field the maker does not publish, so nothing here checks it.

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.
