The Doughnut is the first release from Hubless YoYo, having first come out on Thanksgiving Day 2017.
Developed after several years of research and inspired by hubless wheels, the Doughnut is the first production yo-yo to have a hubless design.
Because of the design, however, the yo-yo uses a unique size of bearing, along with flowable silicone response. The bearing also features a string-centering groove. The Doughnut also comes in a variety of creatively-named colorways, two of which being artist choices from GruntBull Anodizing.
Large at 75.7mm in diameter, the manufacturer recommends throwing it with caution.
