A pair of super light but strong and secure 3K carbon bottle cages. 18-20 grams each Carbon matt finish with weave. After trying a variety of different models I like these most. I've been using my own set of these on road and gravel bikes so can say from personal experience they do the job well (last 2 pics, red frame) . Holds bottles and storage bottles very securely and they look great too. Alloy Mounting screws included.
