I now have over 750 miles on my Radrover and am very happy with it. However, I would like the handlebars to be a couple of inches higher. I went to my LBS and was told that there was not enough slack in the wires to put spacers in and raise the handlebars. I am now considering the Ergon GP5 handlebar grips which will allow me to raise my hands a little higher on the bike. The factory Radrover grips are 5 inches on the left (which I assume is standard) and only 4 inches on the right to accommodate the throttle. If I get the Ergon GP5 grips can I cut an inch off the left side of the right grip and still make it work? Any other good ideas?
