MoYu RS3M V5 – lightweight 3×3 speed cube with dual adjustment
Released in October 2023 as the follow-up to the RS3M 2020, the MoYu RS3M V5 from the Cubing Classroom (MFJS) line rebuilds the classic budget speed cube around a simplified internal structure. Thinner edge pieces and smaller, stronger magnets cut the weight of the cube while keeping turns stable and controllable. Corner and edge magnets provide consistent alignment, and the 9-level adjustment system lets you tune tension and compression to match your turning style.
Three versions share the same 55.5 mm shell. The Magnetic Dual Adjustment edition keeps a spring core with a 9-level dial. The MagLev edition replaces the springs with repelling magnets for a quieter, lower-friction turn. The MagLev Ball-Core UV Coated edition adds 8 ball-core positioning magnets and a full-coverage glossy UV coating for sharper auto-alignment and a brighter finish.
