Setting up the RX for XC racing and singletrack carving means a low, narrow flat bar and a stretched out position. The problem is that this position places the brake levers in a precarious relationship to the top tube. If by some chance I pull a self induced T-bone and launch over the bars I run the risk of having the brake levers smash the top tube. I've seen many a frame ruined by this. If I add headset spacers to the steerer tube to get the bar high enough it defeats the purpose of a lower front end. Does anyone have an idea about how to make a bash guard to protect the top tube? I was thinking about fabricating one out of some PVC pipe and an old inner tube and slipping it over the tube. It'll look lame but it will work. Any ideas?
