You may not think much about your bottle cage, but you probably should. After all, you take pride in the fact that you hand-selected every single component on your magnificent race rig, so why is your bottle cage just an afterthought Fortunately, while you were busy not thinking about your bottle cage, the folks at ENVE were obsessing over it. What they came up with is pretty special. The ENVE Carbon Bottle Cage is made from carbon fiber (what else) with stainless steel hardware. It was designed to keep your water safe and sound in any kind of terrain, and it makes access easy with entry from the top and both sides.
