I was just wanting to know what the pros and cons are of doing the bearing roller mod. I was in a pinch a couple weeks ago and needed a roller fast so I found the thread where a guy shows you how to make your own rollers out of reinforced plastic hose and heater hose. Worked for my ride I went on but it looks like it might wear fairly quick so I was looking at my options for rollers. My lower one was replaced when I built the quad and its holding up pretty good I would say so I wanted to see if there is any real benefits to doing the bearing rollers.
