The Sagmit carbon bottle cage is a lightweight, high-strength water bottle holder made from carbon fiber or a carbon fiber composite. It’s designed to mount using two screws onto the frame’s bottle cage bosses. The carbon material provides an excellent strength-to-weight ratio, making it stiff enough to grip the water bottle tightly even on bumpy terrain, yet light enough that it barely adds weight to your setup. The finish is often sleek, glossy black, or with subtle texture, giving a premium look. Ideal for road or gravel bikes where every gram and aesthetic counts.
