The Doughnut is the first release from Hubless YoYo, having first come out on Thanksgiving Day 2017.
Description[]
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.
