Is it absolutely necessary to change axle size? I know most unresponsive use 10mm axles but some like the shooting star uses an 8mm for responsive and an 10mm for unresponsive. But you don't HAVE to change the axle to play both bearings. Same thing with The Passion by iyoyo, it has a 12mm axle but you can use the 10mm for both responsive and unresponsive.
Hey Evan, do you sell the wedge 1.0 metal hub thing, because I accidentally over tighten when tuning the yoyo, I damage the tread from the hub, I bought it last year, it’s been a year now. I still found no way to fix it. I really like this yoyo. The sad thing is I just bought it for one week, I really wish to change the hub to enjoy the wedge again 😢
