DK Professional-X Complete BMX
What the checker saysnot checked
No fit check runs on a complete bike, and we will not pretend one does. A complete bike does not fill a slot in the builder, so the checker has no counterpart to compare it against and has never produced a single sentence about one.
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.
