Using the Struka Micro - adjustable Bottle Cage is a breeze. To put a bottle in the cage, just place it inside and use one hand to turn the ratcheting twist - buckle to tighten it around the bottle as much as you need. If you want to take the bottle out, simply pull the buckle up. When riding on bumpy roads, make sure to adjust the clamping tightness well to prevent the bottle from falling out. As for maintenance, you can clean it with a damp cloth from time to time. Avoid using harsh chemicals as they might damage the fibre - reinforced resin construction. Store it in a dry place when not in use to keep it in good condition.
