Ultra-light bottle cage for cyclists

The Hollywood Racks ROCKBROS cage weighs 35g and is moulded from polycarbonate. It suits road, mountain, hybrid, touring and electric bicycles that have pre-drilled frame mounts. The silver finish adds a clean look without adding bulk.

Tool-free fit in under a minute

An Allen wrench and two pairs of stainless-steel screws are included so installation takes less than 60 seconds. The frame must already have threaded holes; if they are absent the cage cannot be mounted. Missing hardware should be reported immediately for replacement.

Holds standard and oversized bottles

Wraparound arms grip the bottle firmly on rough trails while rounded corners protect the frame from scratches. The open-sided design allows quick one-handed access while riding. Very large or unusually shaped bottles may not sit securely.

Questions about this item

How can I confirm the cage is holding the bottle securely after installation?

After fitting the cage with the supplied 3 mm Allen wrench and screws, place a full bottle inside; the wrap-around arms should grip it firmly with no movement on rough trails.

What components are included and what must I supply myself?

The package contains the polycarbonate cage, two pairs of stainless-steel bolts and a 3 mm Allen wrench; you only need a bike frame that already has threaded mounting holes.

Which version should I choose for a standard road or mountain bike?

The single silver 35 g model with part number 31210007001 fits most standard and oversized bottles on road, mountain, hybrid, touring and electric bicycles.
