What Size Specialized Mountain Bike Do I Need?

You don’t just ride your bike because you like its design and color. You also need to consider many things. One of which is the size.

Mountain bike size is important because this is where your comfort and control depends on. Factor in your height, weight, and riding style, so you’ll have the perfect fit mountain bike.

It also turns out that Specialized is one of the most popular mountain bike brands out there. And you might have asked yourself, “What size Specialized mountain bike do I need?”

Well, we have the answer to that. This article also shows the different size options and some tips on how to measure yourself.

Specialized Mountain Bike Frame Sizes

Extra Small (XS)

The smallest size for Specialized mountain bikes is extra small. This is also called XS. These bikes are usually used by children and ladies.

They’re also a great fit if your height is 5’0” to 5’3”. Expect these bikes to be very nimble and playful. This is also one reason many dirt jumpers and slopestyle riders prefer XS bikes.

Small (S)

Then there are the Specialized mountain bikes that are sized small. They are ideal for riders who have a height of 5’2” to 5’6’.

This is also a very popular size because they are versatile. They’re not too short or too long. They do well on jumps and cornering because of their short chainstays.

Medium (M)

The size in the middle is medium. This is the most popular size for Specialized mountain bikes because it sits in the middle.

It does well for short and tall riders because of its versatile sizing. But this is ideal for riders who have a height of 5’6” to 5’10”. They are still nimble but are more stable on high-speed sections.

Large (L)

Here come the large-sized Specialized mountain bikes. This is the most common bike size in the US and Europe. Because most mountain bikers in these areas have a height of 5’10” to 6’2”.

These bikes are more stable in high-speed sections because of their longer wheelbase. But they’re not very nimble because of their long chainstays. This makes them a bit hard on tight sections.

Extra Large (XL)

There are also extra-large Specialized mountain bikes that cater to taller riders. They make these for those who have a height of 6’1” to 6’4”.

They have long wheelbases and chainstays. Their reach is also long which makes them a bit hard to control on technical sections. But they are very stable on high-speed sections. They’re also faster when you’ve gained momentum.

Extra-extra Large (XXL)

The extra-extra-large or XXL is the rarest of all mountain bike size chart. They cater to riders who have a height of 6’4” to 6’6”. They have very slow acceleration on the trails and road compared to the other sizes because of their long wheelbase.

But they’re very fast when you’ve gained enough speed and momentum. Their wheelbase and chainstays are very long. This makes them harder to maneuver in tight sections.

Advantages of riding a small mountain bike

There are a lot of benefits when riding a smaller mountain bike. And most of these have to do with the control and maneuverability of the bike. Riding a small mountain bike lets you have more fun on your bike.

You can do tail whips on jumps and drops. This adds more style to your ride. You can also easily put your center of gravity in your preferred position. Because you don’t have to adjust that much, especially that your bike size is already small.

You can easily go through tight corners without doing trials. Or maybe have a better time in handling technical sections because you can easily turn around rocks.

Disadvantages of riding a small mountain bike

Smaller mountain bikes aren’t very stable on high-speed sections because of their short wheelbase. You have a more stable ride if you have a longer wheelbase.

This happens because they distribute your center of gravity across a bigger area. You’ll also have smaller ground coverage with a small-sized bike. This is a disadvantage in races where bigger ground coverage translates to faster speeds.

When do you need a large mountain bike?

Large-sized mountain bikes are ideal if you prefer stability to playfulness. This means you are more of a conservative rider instead of a trickster. Large bikes give you the control you can’t have on smaller bikes.

This happens because of the long-wheelbase which gives you a better center of gravity. You have a lower chance of going over-the-bars as well. You can even roll drops without jumping them. This makes your rides safer and injuries less likely.
