The chariot and trinity are in my opinion, amateur level bolt ons. Of course the customers will be happy because they got a NEW KIT. They don't have to deal with the hassle of figuring out or hunting to find the ones that do work. I have rode a handful of 2/1 bikes and I'm just saying, that the two most common and available setups are leaving a lot to be desired. But if you're new and don't know, how would you even guess the difference.
