The Delta Stream takes the Overlap.Pro concept as its starting point, then tightens up the dimensions and adds a stainless steel ring. The goal is clear: modern competition-ready performance without feeling overly heavy or inert on the throw.
With a 55.5 mm diameter and 50 mm width, it hits a sweet spot for today’s play — plenty of catchability with a clean, controlled feel. At 65.7 g, it keeps enough presence for stability and spin, while still staying nimble and quick in the hand.
Compared to earlier versions, the weight distribution has been refined once more for stronger spin and greater stability — without losing the agile character that makes this size range so fun to play.
Downsized dimensions + stainless ring → stronger spin and stability
50 mm width → modern catch zone without feeling “too wide”
65.7 g → nimble feel with real power reserves

JulyYoYo was founded back in 2020 by the Chinese YoYo player nicknamed “Hornet”. JulyYoYo initially flew under the radar of many players, but thanks to various champions in China and collaborations with other brands as well as a very professional appearance on Instagram, the brand has made a name for itself.
The designs clearly show that there is a real YoYo player with passion behind the brand and not a run-of-the-mill factory that also produces a few YoYos on the side. The quality of workmanship is absolutely world-class, as JulyYoYos are manufactures exclusively in the factory with probably the highest quality standards in the world.
