Analyzing The Usefulness and Practicality of Carbon Water Bottle Cages

Carbon water bottle cages have their benefits, but they’re more of a luxury than a necessity because the component has a low impact on performance.

What Are The Benefits Of a Carbon Water Bottle Cage?

1. Lightweight

Carbon water bottle cages are lighter than cages made of steel, aluminum, and plastic.

The entry-level models are hovering around 30-35 grams whereas the mid and high-range versions drop below 20 grams.

Meanwhile, average aluminum and steel cages can easily reach 50+ grams.

Titanium Cages


The average weight of carbon cages is 23.8 grams. They’re lighter than all other cages and cheaper than some titan models too.

Those properties make them attractive to people who want the lightest possible cage for a fairly acceptable price.

2. Aesthetics

Carbon’s appearance is one of the main reasons why cyclists like it.

Many see average plastic cages as “dull” whereas carbon has a “spaceship look”.

3. Premium Feel

If you have an expensive carbon bike, an ordinary aluminum or steel cage could be seen as an improper stylistic fit, and a way to spoil a luxurious product.

Installing a low tier cage on a high-end bike is similar to putting a cheap 1-dollar cup holder in a Ferrari.

A carbon water bottle cage, on the other hand, preserves the luxury aura of the bicycle.

4. No Deformation or Twisting

Some people experience unpleasant deformation and twisting when using a metal cage.

Conversely, carbon and composite cages are rock solid and do not change their shape during use.

What Are The Downsides of Carbon Cages?

1. Price

The major shortcoming of carbon cages is the price tag. Some models cost more than USD 50. For the same amount of money, you can easily buy multiple cages made of another material.

The price tag is the main obstacle stopping people from purchasing carbon cages.

2. Inflexibility

A steel water bottle cage can be bent to accommodate a larger or smaller bottle without suffering from structural compromises. This is possible because steel is a strong and elastic material allowing the user to cold set (bend) it.

To a certain extent, the same can be done with an aluminum cage, but one should expect some loss of strength because aluminum is soft and loses integrity upon reshaping.

Carbon cages, on the other hand, shouldn’t be re-bent because the material can be damaged irreversibly.

3. Sudden Failure

Unlike steel which is more likely to bend than break, carbon just snaps upon impact.

If your steel cage deforms during a fall, you may be able to put it back into shape, but the same cannot be done with carbon cages broken into multiple pieces.

4. Scratched Bottles

Carbon cages with poor design and/or finish may scratch the water bottle with their rough edges.

5. Non-suitable For Beater Bikes

If you want your bicycle to be a “stealthy beater” (deterring thieves with its cheap look), a shiny carbon cage wouldn’t fit the project.

Do Carbon Bottle Cages Offer a Performance Boost?

The weight savings that a carbon water bottle cage offers are too minuscule to make a difference. An average and even an experienced cyclist will not be hindered if their water bottle cage is 60 grams instead of 30 grams.

The percentage difference between the two is large, but the weight isn’t substantial enough to harm one’s performance.

But even if those grams were essential, you can easily lose them by skipping a meal or keeping your water bottle only 90% full.

Some cyclists say that they prefer carbon water bottle cages for their retention properties, but a quality aluminum or steel cage can hold a bottle just as well.

The Design Is Essential

The material of a bottle cage is only one part of the equation. The design and the build quality are of great importance too.

With the right design, a cage made of aluminum or even steel can become lighter than poorly engineered carbon models.

What’s Wrong With Using An Aluminum Cage on a Carbon Bike?

Technically, nothing. There are great aluminum cages. Some are even lighter than carbon models.

People criticize this practice for reasons that relate more to fashion than function.

Carbon frames are supposed to be an upgrade over aluminum. Putting an aluminum cage on one is seen as poor attention to detail and a way to spoil the lines of the bike.

In practice, however, none of this matters.


  • Carbon cages are aesthetically pleasing but have no direct effect on one’s performance. If your bike is lacking elsewhere, it will be wiser to rely on a cheap cage and invest the remaining money in parts that have a greater carryover to your cycling.
  • Carbon cages are very light and compliment the looks of a modern carbon bike.
