I've Broken Several Things On My Bike, But This Was A First
I was riding along when I heard a loud "tink". My water bottle and metal cage went bouncing out into traffic. After pulling over to retrieve them I noticed the metal had snapped right in front of the top screw. Apparently the back screw had come loose and perhaps the stress had weakened it. The weird thing was I hadn't even touch the bottle in awhile. On the good side nobody ran over my newly purchased water bottle and the remaining screw was still holding my frame pump.
