What Is the 29” Mountain Bike Wheel?

Mountain bike wheels come in many different sizes. Older bikes were 26”, then you got 29,” and in recent years, we now have 27.5”’s. A 29” wheel is the largest current mountain bike wheel you will find on the market. It’s used in many different mountain biking disciplines, such as cross-country, trail riding, and even enduro.

A 29” wheel is actually the same size as a 700c road wheel. It is referred to as a 29” because it is designed for mountain bikes and they measure using the standard system compared to road bikes which use a different measurement system. Although the same size, the 29” is internally much wider than a 700c.

A 29” wheel is made up of many parts. The rim is the piece on the outside where the tire sits and on mountain bikes typically has a very low profile. Then connected to that, the nipples and spokes which lead down to your hub in the center, where the bearings and freehubs sit.

Being made for mountain biking, 29” wheels have to be lightweight, strong, and have flexibility under impact. They are typically made of aluminum. High-performance wheels will be made of carbon fiber. You can expect a set of 29” wheels to weigh anywhere from 1kg to 2.2kg in weight without tires or inner tubes.

The History

The 29” wheel was first used in the 1980s but wasn’t mainstream. It was only used by professionals for certain testing and in certain races. Companies did try to push these, but it never really caught on. Come 1999, lots of mountain bike companies started releasing bikes with 29” wheels, and a decade later, it was the majority of what riders were using and still, to this day, one of the most popular sizes of mountain bike wheels because of its ability to perform and many tire options.

What are the Pros and Cons of 29” Mountain Bike Wheels?

Like any piece of cycling equipment, it has its advantages and disadvantages. There are many reasons to pick a 29” mountain bike wheel over a 26” or 27.5,” and there are some reasons why they might not be ideal.

Pros

Top Speed

The beauty of riding wheels that are a larger size is that they have the ability to hold much higher speed with less effort. The larger diameter means the momentum carries further, your gearing can take you to high speeds, and it rolls much smoother.

Roll Over Ability

29” wheels have an excellent ability to roll over obstacles much better than smaller wheels such as 27.5” or 26”. This means that for situations like rolling over gravel, small rocks, or even tree roots, the bike can get over much faster, and it will feel much smoother.

Larger Contact Patch

When we speak about contact patches, we’re talking about the amount of rubber on the tire that sits on the floor. With 29” wheels, the contact patch is very large, and with more contact with the ground, the more grip you will have on the floor.

Flexibility

With larger wheels, you get longer spokes, providing extra flexibility when hitting bumps. This means wheels feel excellent to ride, and you know on the big impacts, they will rebound well.

Cons

Weight

Since a 29” wheel is larger than a 27.5” or a 26”, it generally weighs a little bit more. Also, if you had like-for-like tires with a smaller wheel, it would also weigh slightly more as it would require more rubber compound to travel further around the wheel.

Less Agile

Bigger wheels are better at going over obstacles, but smaller wheels are much better at going around obstacles. Smaller wheels like 27.5” are much more agile and responsive than larger wheels such as 29”.

Tire Sizes Are More Limited

Typically larger wheels have less space in the frame. You will find that less you will be limited to tires up to about 2.4”. When on a smaller set of wheels, such as 27.5” or 26” will generally be able to fit in a frame with larger tires on them.

They Don’t Work for Everyone

29” wheels are larger, and because of this, they don’t always work for shorter riders. Some bikes in smaller models will come with 27.5” wheels instead of 29” wheels. This is because larger wheels can make the bike too tall.

How to Find the Right 29” Bike for You?

29” bikes come in all different shapes and sizes, and finding the right one for you can be challenging. Here are the questions you should ask yourself when searching to find the right bike for you.

Discipline

Cross country, trail, enduro, and downhill, you first need to consider what kind of riding you will be doing. Once you know the riding you want to do, get a 29” bike which is going to have the ability to help you conquer the trails you have planned.

Budget

There is a lot of choice of 29” bikes you can choose from, find out what your budget is and then look for bikes that fall into that price range. Don’t be shy of a cheap bike, as you can have just as much fun. They just might not be as fast.

Size

You might have found the perfect bike for you on your travels, but you need to ensure it’s the right size for you. We highly recommend not compromising on the size as it will make the ride uncomfortable. Another thing to look out for is to check the wheel size on smaller bikes because sometimes they drop them to 27.5” for smaller riders.

Brand

We also recommend going for a reputable brand. The reason why brands like Giant, Trek, and Specialized are so popular is because they make great bikes. The same goes for components getting gearing from top brands such as Shimano, SRAM, or Campagnolo will last longer, be more reliable, and give you a much better experience while out on the trails.

Warranty

When looking for a 29” bike, you always have the option to go secondhand, but this does come with lots of risks, such as the bike could have issues working correctly, been dropped often, or even. Unlike when you buy a new bike, you know it will be perfect, it will come with a warranty, and many shops offer a free first service.

Who Is a 29” Bike For?

A 29” bike is ideal for many riders. They have certain characteristics which benefit certain types of riders. The first thing to mention is 29” wheels being large to suit taller people. Larger wheels generally work better for taller people as they help the bike’s geometry for a larger rider.

29” bikes, as we discussed before, also are great at rolling over objects better than going around them. This makes them perfect for XC racing and lighter trails at higher speeds. The best mountain bikers in XC generally ride 29” wheels as they are very efficient and make the work easier.

Another great feature of a 29” bike is that it is excellent at higher speeds compared to a 27.5” bike or a 26” bike. So if you are riding on flats or plan to be going at higher speeds, you will have a much easier time using a bike with 29” compared to a bike with smaller wheels.

Conclusion

When people started seeing 29” bikes on the cycling scene, they saw them as a passing fad, but over time, they grew to be one of the most popular wheel sizes that have ever come to mountain biking, and we won’t see it going away anytime soon.
