First released: February 2013


We set out to create a Side Effect yoyo that was pocket friendly and budget friendly without sacrificing performance. The result is the Yelets.

The Yelets blends the modern aspects of Side Effects with the classic attributes of affordability, performance, and simplicity continuing the tradition established by the Project, M1, and CafeRacer. We want to take the lead in bringing back smaller yoyos and we felt that 52mm was the perfect diameter. It is bigger than what is traditionally thought of as "undersized" (for example, the M1 is 50mm) to retain the performance of a big yoyo but small enough to give you confidence with chop sticks or tight tech tricks.

Once we had the specs perfect, we came up with a crazy idea for the name. We decided to map the diameter and width to latitude and longitude by plugging the numbers into Google Maps to see where it would end up. The result was a small city in Russia called Yelets.

The suggested retail price is $85 for solid colors making this the first Side Effect yoyo at this price.
