The key word here is "Rossetti", which in Elite-speak means this cage is made from a high-impact composite material that looks like carbon fiber, but isn't carbon. Its "carbon-look" finish gives it the same carbon-y exterior. But it's composite construction saves you a boatload of cost in comparison to true carbon without sacrificing style, lightness, or bottle security. In fact, it has the same self-adjusting 'V' design as the Custom Carbon, allowing the Rossetti Bottle Cage to adjust to the size of your bottle. The Elite Custom Carbon is the ideal choice for a cost-is-no-object cyclist. But if you're the kind of rider who loves to maximize performance-per-dollar, the Rossetti Bottle Cage is made for you.
