What Size Specialized Mountain Bike Do I Need?

You don’t just ride your bike because you like its design and color. It would be best if you also considered many things. One of which is the size.

Mountain bike size is important because this is where your comfort and control depend 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 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 MTBs is extra small. This is also called XS. Children and ladies usually use these bikes.

They’re also a great fit if your height is 5’0” to 5’3”. Expect these bikes to be very nimble and playful, ideal for the shorter rider height. This is also why many dirt jumpers and slopestyle riders prefer XS bikes.

Small (S)

Then there are the Specialized mountain bikes that are sized small. These are called S-sizing bikes that are ideal for those that have a shorter rider height. They are great for riders with a height length of 5’2” to 5’6’.

An S size is also a very popular size because they are versatile. They’re not too short or too long. S-size bikes do well on jumps and cornering because of their short chain stays.

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, unlike bikes that have S sizing, which is geared for riders that have a shorter rider height.

But this is ideal for riders with a height and length of 5’6” to 5’10”. Medium-sized Specialized bikes are still nimble but are more stable in 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, contrary to the S-sizing bikes common in Asia. 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 chain stays. An example of 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 with a rider height of 6’1” to 6’4”.

An XL bike size features long wheelbases and chainstays. Their reach is also long, making it difficult to control in technical sections. But they are stable on high-speed sections, have a style-specific sizing ideal for xc bikes, and have tall ride heights. XL Specialized bikes are also faster when you’ve gained momentum.

Extra-extra Large (XXL)

The extra-extra-large or XXL Specialized bike is the rarest of all mountain bike size charts. They cater to riders with a height of 6’4” to 6’6”. They are not road and trail bikes because of their long wheelbase, resulting in very slow acceleration.

But these Specialized bikes are very fast when you’ve gained enough speed and momentum. Their wheelbase and chainstays are very long. This makes XXL-size bikes harder to maneuver in tight sections, unlike S-sizing bikes.

Advantages of riding a small mountain bike

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

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

You can easily go through tight corners without doing trials. Or maybe have a better time handling technical sections because you can easily turn around rocks if you get the right bike sizing and correct size.

Note that bike sizing for a Specialized bike is very important for you to make the most out of your Specialized bike. This includes the rider height, frame size, body size, and measurements of each part, like the top tube, standover heights, and frame.

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 an S-sizing bicycle. This is a disadvantage in races where bigger ground coverage translates to faster speeds.

When do you need a large mountain bike?

A large mountain bike size is 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 of Specialized, 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 on Specialized bicycles without jumping them. This makes your rides safer and injuries less likely because you factored in the rider’s height for the optimum experience.

Getting the right mountain bike size is important because this affects your riding. Having a size smaller than your weight makes the ride uncomfortable.

Your ride isn’t very stable, and you have a higher chance of getting injured. Meanwhile, a bike that’s larger than your intended size feels heavy. You also can’t easily move.

What’s also great with Specialized bikes is that the total purchase price can be subject to installment plans using your credit limit and PayPal credit.

Make sure that the shop you’re buying one from offers credit products and has a rights reserved company reputation alongside a registration number so you can keep up with legal matters.

Also, ensure that the credit provided the subject interest rate of the total amount is low. You need to consider these technical matters aside from factoring in the right frame size and rider height so you can have a great time with your Specialized bike.
