To bad this does not work with the QDII system. I have broke a cv while while on the trail & it does suck. Now I am not sure about the QTII system but I do know from experience that if you break an cv on the QDII system that it will still move under its own power while in 4lo.
I want stronger cv's so hope they do make them for the QDII
I did send them a message to make sure that they do not make on that will work with the QDII system.
