Using this Topeak DF Duo Fixer Mount is a breeze. First, check if your saddle rails are compatible. It works with steel, CroMo, titanium, and carbon standard rails with 36mm width and at least 30mm height, but avoid monorail or spring - type rails. Then, use the simple slide - and - click mechanism to attach your QuickClick - equipped accessories or strap - type saddle bags (with the included adaptor) under the saddle. For a creative setup, you can mount lights above fenders or bags. When you're done with your ride, easily remove the accessories without any tools. To maintain it, keep it clean from dirt and debris. You can wipe it down with a dry cloth after each use. If it gets wet, dry it thoroughly to prevent rust and corrosion.
