what makes you think it's the VX? not saying it's not, just that there are no model identifications on it, other than "Edge" and all the photos I can find on the WWW show "Edge First", "Edge Racer", "Edge VX", etc.
are there any distinguishing features from one model to another? tube shaped? lugs? I'm not really bothered either way, but it would be good to know for sure!
