The company that invented the low cost high performance metal yo-yo is back with their new economic model the Y Factor. The Y Factor is a synthesized version of One Drop's past works rolled into one awesome bundle using the cut rim grooves from the Projects, and the round-nut axle system used on M1s and Dingos, plus the well tested Flow Groove silicone response pads and large size C 10ball bearings for response. Grinders will be happy to see a newly designed and quite epic grind lip. The Y Factors also come standard with One Drop's new Pyramatte (tm) finish giving it a smooth and unique finish that is super durable. We also have nickle plated versions as well. One Drop wanted to get rid of any X Factors, so the Y Factors emerge.
