## Long description

Rockbros FK338 is a lightweight on-frame water bottle cage made from durable polycarbonate (PC). Designed in black for discreet integration with most bike frames, this single-pack bottle holder secures standard cycling bottles for everyday rides, commuting and leisure use. It is intended as a direct replacement or upgrade for existing cages and requires correct fastening before each ride; it does not include a suction cup.
Advantages
The PC construction delivers a balance of low weight and impact resistance while maintaining stable grip on bottles. Its minimalist profile reduces interference with frame bags and pedals, and the universal on-frame mounting fits most standard threaded bottle cage bosses. The single-piece design is simple to maintain and easy to install, providing a practical solution for riders seeking a lightweight, unobtrusive bottle holder.
Suitable for
Road and hybrid bikes for commuting and casual rides
City bicycles where a compact, low-profile cage is preferred
Replacing worn or damaged bottle cages
Adding a spare cage for multi-bike households
Key specifications
Material: polycarbonate (PC) for low weight and toughness
Colour: black
Mounting: on-frame, fits standard bottle cage bosses
Pack quantity: 1 piece
Suction cup: not included
How to use
Mount the cage to the bike frame using the two threaded bosses and appropriate screws (not supplied). Position the cage so the bottle can be inserted and removed comfortably without interfering with pedaling or accessories. Before each use, check that the cage is securely fastened and that screws are tight. Insert a standard cycling bottle until it is held firmly by the cage; remove by pulling the bottle outwards with a slight angle as needed.
Usage recommendations
Regularly inspect mounting screws for tightness and check the cage for cracks or wear. Use with standard-diameter cycling bottles; avoid forcing oversized containers. If riding on rough terrain, verify the bottle is retained securely before starting and consider using a cap or bottle with a secure lid to prevent spills.
