For a long time YoyoFactory didn’t enter the market with a Yoyo designed specifically for the competitive style known as 4a. There was a lot of other good options for players. A recent conversation with a friend and retailer finally convinced YoyoFactory to make this a reality. Design wise we have been recommended many ideas, some conflicting, but stuck to the elements we liked. It has a Simple design. Nothing super radical, a stepped profile. Inner foil to assist with grinding tricks. Durable thanks to premium materials (polycarbonate) and a thicker stronger axle. Easy to maintain with standard parts and spacers which are slightly looser fit.
