About the JDS Boss
The Boss was originally released by YoyoFactory in 2009 as an undersized H-profile metal that gained a devoted following despite non-standard specs for its era. The JDS Boss is a 2022 redesign by SUS YOYO MECHANICS, widened 3mm from the original while maintaining the H-profile shape and undersized 50.96mm diameter. Wall thickness around the axle was minimized to improve power transfer. Available in standard ($39.99) and Jun special edition ($49.99) colorways: Blue Jun, Silver, Orange Jun, Blue, Red, Green Jun, Gold Jun.
