This is a FIDLOCK bottle and bottle cage set. It's magnetic, so the bottle is unlikely to fall out. When the bottle is removed, the road bike looks clean and cool. I'm selling it because I haven't been using it recently. It has been disinfected. This is a used item, so please refrain from returns or claims. - Brand: FIDLOCK - Type: Bottle - Mounting: Magnetic - Mouth Diameter: Standard Thank you for looking.
