A pair of high - quality bottle bobs and hose clamps. They're perfect for securely attaching downtube and water bottle batteries to frames that lack eyelets, ensuring a stable and reliable setup.

Using these bottle bobs is easy. First, place the battery where you want it on the frame. Then, use the hose clamps to attach the bottle bobs firmly to the frame and around the battery. Make sure the clamps are tight to prevent any movement. When it comes to maintenance, regularly check the clamps for tightness. If they seem loose, simply tighten them up. Also, keep the bottle bobs clean by wiping them with a dry cloth. Avoid using harsh chemicals as they might damage the product. This will keep your battery secure and your setup in top - notch condition.
