Sorry the Aim solo2 wasn't for sale. I did sell it a month ago to a buddy because I upgraded to the DL version. sorry. But no they are GPS so they just work and there is a guy in the uk that makes good fork mounts for them but can't recall his name. All that is listed in the last update post I made is what I have left.How much for the Aim Solo 2. And does it work as a stand alone device? Do you have mounting for it?
