I am thinking about buying a bike and wondering if I can use V-Brake Levers with the BB-5 Disk? Also in my eye its better but was thinking about replacing the Deore Shifters and Avid FR-5 Levers with a LX combo shifter brake lever. I currently on my old bike have LX combo but old model. Feel I can do it and sell stock levers and shifters and would only have under $20 in the change. Good Idea? bad Idea? Not worth my time?
