This is far from the first time that someone has created a cageless water bottle. Rhode Gear had one that I really liked because they made a plastic clamp on version that didn't scratch the paint on my Raleigh Professional that had no water bottle bosses. They also made a version of the holder that fit standard water bottle bosses. Held the bottle securely and was super easy to put the bottle into the holder. Cannondale also had a cageless holder that used velcro to hold the bottle in place. Again, simple to get the bottle in and out of the holder
