This is the Archetype Frame Only (Open Box) version. It includes the core carbon frame, TPU parts, XT60 battery port, and battery strap, but does not include the full hardware kit or pre-cut wiring normally supplied with the standard frame kit. The frame is packaged loose in the box rather than in the full retail packaging. This option is ideal for builders who already have spare hardware and wiring and simply need the Archetype frame and printed parts. This kit is not defective. It comes from overstock frames that were originally prepared for full retail box kits.
