Stopping is just as important as going in cycling, so why leave that duty up to inferior brake pads? The Kool Stop Dura2 insert is a newly designed road pad insert. The pad is thicker than their standard Dura type for longer life. Plus, it has a 7.65 mm contact width for narrow rims and cut outs for reduced weight. Finally, the pads sit flat on the rim for superior modulation. If you want to go with a pad that you know can handle the responsibility of slowing and stopping, then you"ll be glad you chose Kool Stop. Choose from Black (standard compound; MFG Part Number KS-DR2B) or Salmon (most aggressive compounds for extreme all weather conditions; MFG Part Number KS-DR2SA) Water Grooves for max stopping power in adverse conditions 7.65 contact width Reduced weight Rim Friendly Compounds
