From One Drop:
“The 54 is the first full size release from One Drop. It is named after the diameter which is 54mm. It is designed to be floaty and is the first yo-yo to use the Side Effects axle system. You will get aluminum spikes as pictured as well as brass domes. We’ll have many more available in the future that you can use with this yo-yo.”
The 54’s innovation of Side Effects has had a huge impact on yo-yo design, with many other companies licensing out usage of the system. There is a huge assortment of Side Effects available today in many different styles, materials, and colors.
