thats probably good. I got a torker dx first adn it is pretty good and costs a little less. My uni now costs a lot more because really good trials unis cost around 330 i think but the cheeper ones are probably good.
That one is excellent for trials riding, nice and strong and not too heavy. The seat is a little thick for seat in front jumping, but it is managable. If you wanted you could buy a thinner one or modify it yourself, but as it is it works nicely.
The Qu-Ax unicycle is a pretty good choice, its extremely strong, only thing I ever broke on my Qu-Ax was a saddle, and they all have the same Velo plastic seatbase. Good uni for the price.
So does Koxx, the new Qu-Ax rim is a very good and wide rim, most probably you’ll get the new rim if you order it. I’m not saying the old rim is bad, I’ve done 2 meter drops on it, screwed up my ankles, and the dear old Qu-Ax was doing just fine.
