The cage is made from polycarbonate (PC), a rigid yet impact-resistant plastic that is generally lighter and more affordable than aluminium alloy cages, though aluminium cages tend to offer slightly better long-term wear resistance under heavy daily abuse. For typical Indian riding conditions including rough roads and occasional bumps, the polycarbonate build holds up well while keeping the overall bike weight down.

The cage is designed to hold standard-diameter cycling water bottles, including most 600ml-750ml bottles, and mounts using the standard two-bolt pattern found on the vast majority of road bike, MTB, and hybrid frames sold in India. It's a good idea to check your frame's bottle mount spacing if you have a non-standard or compact frame.

Installation is straightforward: align the cage with the two threaded bosses on your frame's down tube or seat tube and secure it with the bolts provided or your bike's existing cage bolts, using a standard hex key. No special tools or professional fitting are required, and the cage can be installed in a few minutes at home.

All four gradient colour options, Black, Black/Blue, Black/Red, and Blue/Purple, share the same polycarbonate construction, bottle grip, and mounting hardware, so performance and durability are identical regardless of which colourway you pick. The choice is purely about matching your bike's colour scheme or personal style.

This bottle cage is a genuine, authorised Rockbros product rather than an unofficial copy, so you get the described polycarbonate build and gradient finish.
