I have a F7 snopro that I am thinking of tacking the inner wheels off . I saw the way the snowcross sleds are set up and they don,t have any inner wheels . I am also purchasing 8'' billet wheels to replace the rear wheels from mountain machines . I would like to know if any one else has tried this set up and if there is any benefit? I heard that you would get better longevity from the hyfax and a more even wear. I also heard that I would get a better hole shot . Advice and input appreciated!!! Thanx!!
