Today, we’re diving deep into the world of BMX rims to compare two of the most commonly discussed types: Single-wall and double-wall rims.

Knowing the difference between these two can be a game-changer.

Stick around as I lay down each type’s facts, advantages, and disadvantages.

My aim? To help you make a more informed decision the next time you’re in the market for new rims.

Hint: STAY AWAY of single-wall rims!

Single-Wall Rims

You might have heard the term tossed around in biking circles or seen it in the spec sheet of a bike you’ve been eyeing.

But what does it mean, and why should you care?

Let’s break it down!

What Are Single-Wall Rims?

In the simplest terms, single wall rims are made up of a single layer of material that connects the tire to the hub of the wheel.

Imagine a simple hoop with a groove for the tire and holes for the spokes β€” yup, that’s a single wall rim for you.

These are the OG rims that probably came with your first BMX bike or that retro ride you might have picked up at a garage sale.

I’m sure many of you remember these because of TOO MANY flats caused by them.

I was the happiest kid alive when the double-wall rims came out.


Regarding materials, single-wall rims are typically made of aluminum alloy, which is both lightweight and decently strong for most casual riding needs.


The design is straightforward – a single layer of material is shaped into a hoop with indentations or grooves where the tire sits.

No frills, no extra layers, just a simple, straightforward structure that’s easy to understand and even easier to install.

Advantages Of Single-Wall Rims


One of the biggest draws of single-wall rims is that they’re usually cheaper. If you’re on a tight budget or just starting with BMX, these could be a great option.

Lighter Weight

Because of their simpler construction, single-wall rims are generally lighter, making it easier to get those jumps and tricks off the ground.

Easier to Manufacture

The simple design means they are easier – and cheaper – to manufacture. That’s why you’ll find a lot of entry-level bikes equipped with single-wall rims.

Generally Good for Casual Use

If you plan on cruising around the neighborhood, hitting the local skatepark, or doing light trail riding, a single wall rim should serve you well.

Disadvantages Of Single-Wall Rims

Less Durable

The flip side of being lightweight and simple is that single-wall rims are less durable.

You don’t want to use them to send a (big) drop and expect them to survive because they likely won’t.

Susceptible to Dents and Damage

Because they are made from a single layer of material, these rims can be more susceptible to dents, especially if you accidentally hit a pothole or have a rough landing.

Not Ideal for Rigorous Activities

If you’re into serious BMX shredding, you WILL find that single-wall rims don’t have the toughness you need.

Double-Wall Rims

Now it’s time to meet the big league player on the block β€” the double-wall rim.

If you’re thinking about getting serious with your BMX adventures or just want something that can take a beating, then you’ll definitely want to stick around for this!

What Are Double-Wall Rims?

Simply put, these rims have not one, but two walls of material, providing extra strength and durability.

Imagine a regular rim but beefed up with an additional inner layer that adds EXTRA support.

Yeah, we’re talking about the SUV of rims here β€” stronger and ready for anything.


Just like their single-wall cousins, double-wall rims are made of aluminum.


This is where things get interesting.

Double wall rims have an additional inner wall that supports the outer one.

This dual-layer structure makes them substantially more durable, allowing them to effectively distribute stress and impact.

Advantages of Double-Wall Rims

Increased Durability

This is the major perk!

Double wall rims are like the bodybuilders of the rim world.

They can take a lot more abuse, making them ideal if durability is a high priority for you.

Greater Stability

Because of their reinforced structure, these rims provide greater stability during your sessions.

Whether doing jumps, tricks, or navigating rough terrain, double wall rims can help you feel more in control.

Suited for a Wide Range of Activities

From cruising city streets to extreme BMX shredding, the versatility of double wall rims makes them suitable for any kind of riding.

Disadvantages of Double-Wall Rims


The extra material does add weight. If you value a super lightweight setup, this could be a downside for you.

But even if you want to make your BMX bike lighter, I still don’t recommend using single-wall rims.

More Expensive

Quality comes at a price, folks! The added durability and performance capabilities mean you’ll typically spend more on double-wall rims.

Nipples are Harder to Access

Because of their complex structure, adjusting the spokes can be a bit more challenging as the nipples are harder to reach.

Key Differences Of Single- & Double-Wall Rims

Feature Single-wall rims Double-wall rims
Definition Single layer of material connecting the tire to the hub. Double layers of material, an inner and an outer wall, for added strength.
Structure Simpler, lighter design. More complex, includes inner & outer walls for greater strength.
Weight Lighter. Heavier.
Durability Less durable. More durable & able to withstand greater abuse.
Suitability Good for casual riding & light trail use. Suited for heavy street, park & trails shredding.
Cost Less expensive. More expensive due to complex construction & greater durability.
Nipple accessibility Easier to access for spoke adjustments. Nipples are harder to reach, making spoke adjustments a bit more challenging.
Risk of dents/damage More prone to dents and damage. Less prone due to reinforced structure.

Conclusion: Stay Away From Single-Wall Rims

While there are some parts on a BMX bike that you can go with the cheaper version, I don’t recommend you go with the cheaper rim version.

In other words, if you are getting new BMX rims, don’t look at single-wall rims – unless you’ll have your BMX for commuting exclusively.

It’s better to get a cheap double-wall rim than any single-wall rim.

The enhanced durability and greater stability of a double-wall rim provide better performance and an added level of safety that’s hard to put a price tag on.

Unfortunately, entry-level complete bikes mostly come with single-wall rims.

So riders who start progressing will likely need to replace the front and rear rims soon (or at least when they’re completely destroyed).
