Race X Lite Carbon Cage A full carbon construction & a revised shape make Bontrager's Race X Lite cage lighter & consistently dependable. The Rubber gripping pieces combine with the tension in the carbon ensure a firm, rattle free hold on your bottle without making it hard to remove. One thing worth noting for carbon weave lovers is that the black version we have here actually has a black finish & doesn't show the carbon weave pattern like the one in the picture. Still made from carbon, just like the white one, but finished in gloss black. Full carbon construction 23 grams Rubber grippers for enhanced bottle retention Designed to offer secure bottle hold & easy bottle removal Suitable for MTB & road use
