The YoyoFactory Nightmare is one of the first bi-metal designs with a overhanging steel rim, they didn't just slap a steel ring on the yo-yo, they wrapped it over the edge and down to create maximum spin stability and capture more rotational energy. This steel rim placement gives the Nightmare a really beautiful weight distribution and an amazingly fast and stable feel in play. It allows this light weight yo-yo to perform with the power of a much heavier yo-yo and creates the ability for the player to move faster through trick segments!
