Aluminum Alloy Bicycle Water Bottle Cage Holder Lightweight Side-Load MTB Bike

Staying hydrated on a long climb or a fast commute should never mean wrestling with a flimsy plastic cage or worrying about your bottle bouncing loose over rough terrain. This bottle cage is built from aluminum alloy and finished with a T6 heat treatment, giving it the strength of metal without adding bulk to your build. Every cage is designed with a smooth side-load opening that holds your bottle securely while sliding it in and out without scuffing or scratching the bottle surface, solving a common complaint with traditional rigid top-load aluminum cages. With universal mounting holes, it bolts straight onto the standard two-hole boss found on the vast majority of mountain bikes, road bikes, gravel bikes, and commuter frames, making it a simple, lightweight upgrade for any rider who wants dependable bottle storage that will not let go mid-ride.

Available Specifications

High Quality Material and Lightweight

Constructed from premium aluminum alloy and treated with a T6 heat treatment process, this cage is engineered to be super strong while keeping total weight down to about 41.5 grams, with the listed spec confirming a weight of less than 75 grams. That means it adds virtually no noticeable weight to your bike while still standing up to the vibration, impact, and constant load cycles of daily riding, gravel paths, and singletrack trails.

Never Lose Another Bottle

The cage's frame is shaped to deliver a genuinely tight, confident hold on your bottle so there is no need to worry about it flying out over bumps, drops, or sharp turns. If you have ever dealt with a bottle popping loose on a traditional top-load aluminum cage, this design is built specifically to give you peace of mind on every ride.

Smooth Opening To Protect The Bottle

Aluminum alloy cages can be tougher on a bottle's surface than soft plastic cages, so this cage uses a specially shaped, smooth-edged side opening that lets you insert and remove your bottle without scraping or scuffing it. The curved entry point eliminates sharp edges along the insertion path, so your bottle slides in and out cleanly every time.

Six Color Options

This cage is offered in six different finishes, giving you the flexibility to match it to your frame, your other components, or simply your personal style. Whether you run an all-black setup or want a pop of color on your downtube, there is a finish to suit your build.

Mass Compatibility

The cage uses a universal mounting hole design, which lines up with the standard two-bolt boss pattern found on the overwhelming majority of bicycle frames. This makes it compatible with mountain bikes, road bikes, gravel bikes, and commuter bikes alike, so you can mount it on your down tube or seat tube without hunting for a special fit.

What's Included

Installation Guide

  1. Locate the two threaded bottle boss holes on your frame's down tube or seat tube.
  2. Align the two mounting holes on the back of the cage with the threaded bosses on the frame.
  3. Place a washer onto each of the two included bolts.
  4. Insert each bolt through the cage's mounting holes and into the frame's threaded bosses.
  5. Use the included hex key to tighten both bolts evenly, alternating between the two to keep the cage seated flush against the frame.
  6. Check that the cage sits flat with no wobble, then test the fit by sliding a standard cycling water bottle into the side opening to confirm a secure, snug hold.

Ideal Use Cases

This cage is suited to mountain bike trail riding, road cycling, gravel adventures, and everyday commuting alike. Its lightweight aluminum alloy build and secure side-load hold make it equally at home on a cross-country mountain bike tackling rough singletrack as it is on a road bike covering long paved miles, keeping a standard cycling water bottle exactly where it belongs throughout the ride.
