## Long description

Rockbros FK338 Black Red is a lightweight alloy bicycle water bottle cage designed to secure standard cycling bottles on a wide range of frames. Finished in black with red accents, the FK338 provides a balance of low weight and structural rigidity for road, gravel and urban bikes. The open-sided shape allows quick insertion and removal of bottles while keeping them firmly in place during rides. It installs on standard bottle bosses using two bolts and is compatible with common cycling bottle sizes.
Advantages
The FK338 offers a low-weight construction that minimizes added mass to the frame while preserving firm bottle retention. Its alloy material provides corrosion resistance and durability for everyday use. The shape and mounting design ensure secure holding even on bumpy surfaces, and the open profile enables easy one-handed operation when reaching for a bottle in traffic or during intense efforts.
Suitable for
 Road cycling where low weight and quick access matter
 Gravel rides that require secure retention on rough terrain
 Urban commuting for regular hydration on city bikes
 Casual and training rides with standard cycling bottles
Key specifications
 Material: lightweight alloy
 Finish: black with red accents
 Mounting: fits standard frame bottle bosses, two-bolt attachment
 Compatibility: designed for standard cycling water bottles
 Design: open-sided profile for easy insertion and removal
How to use
Attach the holder to the bicycle frame by aligning it with the frame's bottle bosses and securing it using two bolts. Tighten the bolts to a snug torque appropriate for frame fittings to avoid loosening during rides. Insert a standard cycling water bottle by pushing it into the cage until it clicks into place; remove it by pulling outward and upward. Check bolt tightness periodically and ensure the bottle fits securely before each ride.
Usage recommendations
For best performance, use bottles with standard diameters and avoid oversized containers that may not seat correctly. Inspect mounting bolts and the cage for damage after heavy impacts. If you ride on very rough terrain, periodically verify that the holder remains firmly attached and that the bottle does not rattle free.
