The Cageless water bottle is a cycling water bottle, developed by British cycling design company Fabric, that does away with the ubiquitous water bottle cage. Most cyclists don't really pay attention to their water bottle cage, but it is actually one of those things that could be refined and optimized.
This bottle's design is rather simple. Rather than necessitating the use of a bottle inside a separate cage, Cageless comprises a BPA-free 600-milliliter bottle with built-in retaining clips and a number of plastic studs, that can be mounted on the bicycle's existing cage boss.
This setup ensures that there's no naked bottle cage sitting on the bicycle frame when the bottle isn't used, and also makes it easier to retrieve and attach bottles.
