What Are 29 Inch Mountain Bikes?

When we call a bike a 29-inch mountain bike, we are referring to a bike type that is specially designed to be ridden in the mountains — and thus, a mountain bike — and that bike has a pair of wheels with a diameter of 29 inches.

To put things into perspective, bike wheel sizes start from 12 inches for toddlers, and kids’ bikes have up to 26-inch wheels. Adult bikes typically have three wheel sizes: 26 inches, 27.5 inches, and 29 inches. Thus, 29-inch mountain bikes are the mountain bikes with the biggest standard wheel sizes. (Of course, you can have custom bikes, and there are some exceptional bikes besides custom bikes, with over 30-inch wheels).

So, is having bigger wheels better than having smaller wheels? Well, while there are pros and cons for both sides, the short answer is yes: 29-inch mountain bikes are the best mountain bikes on the market.

Advantages of 29 Inch Mountain Bikes

It used to be that 26-inch mountain bikes were the standard for mountain biking for over three decades. Here is a review of the best 26-inch mountain bikes. However, since 2010, the 29-inch bike has revolutionized the mountain bike industry with its numerous advantages. These are detailed below.

Availability

29-inch mountain bikes are the standard for mountain biking today, and so you can bet that most brands — big or small — manufacture 29-inch mountain bikes. That doesn’t mean you won’t find 26ers or 27.5ers, but 29ers will be the featured mountain bikes on sale.

This also means that the latest technological advancements made in the bike industry are catered to 29-inch bikes. Bikes of other wheel sizes may or may not receive the latest updates, at least not immediately. Therefore, if you are a bike enthusiast or like to keep your finger at the pulse of the latest happenings, you’ll for sure want a 29-inch mountain bike.

Frame Geometry

One major reason why 29-inch mountain bikes are so widely available is that modern frame geometry is catered to them. In contrast, 26-inch mountain bikes do not have that luxury.

The current trend in frame geometry is progressive geometry. This means the reach is longer, the head angle is slacker and longer, the top tube is longer — basically, a longer front center. The current frame geometry also allows more customizability. You will have much more legroom and can adjust your seats.

Rolling Resistance

Mountain bikes are built for having low rolling resistance, and the bigger the wheels, the less the rolling resistance. This means 29-inch mountain bikes are great at dealing with rolling resistance.

But what exactly is rolling resistance? It’s the resistance or inertia or force that works against your bike rolling over obstacles on the road. As we know, mountain bikes are designed to ride on unpaved terrain, meaning they have to handle tiny rocks and twigs, and other dirt. The bigger wheeled 29ers can quite easily plow over these road hurdles. A 26-inch mountain bike also has traction to go over small hurdles, but they are significantly less capable of doing so than 29ers.

How significant is the rolling resistance discrepancy between a 29-inch mountain bike and a 26 inch one? Well, you might scoff at the difference, as it’s just about 5%. Yes, 29-inch mountain bikes have only about 5% more roll-ability than their 26-inch counterparts. But we kid you not: this 5% difference really adds up on a journey. And not only is the cumulative difference noticeable, but you will also feel the world of difference in this 5% difference in rolling resistance.

Speed

Some interesting bits of nuance here. You see, 29-inch bikes are faster than 26-inch bikes. But their acceleration is lower. This means that since a bike with smaller wheels is more nimble, it can pick up speed more easily. This helps with turning corners, and also if you stop and start a lot, like due to heavy traffic.

However, the advantage of 29ers over 26ers and also 27.5ers is the top speed. Although the 29-inch bike can take slightly longer to pick up speed, its maximum speed is higher. Why exactly is that?

It’s due to the larger wheels. If we pit a 29er against a 27.5er and a 26er, and if all three bikes have the same gears and quality components, then the 29er will take first place, the 27.5-second place, and the 26er last place.

Say, you go at 100 rpm (rotation per minute). Each rotation, however, won’t be the same for the three bike types. The 29er will cover more distance simply because of the larger wheels, and hence, its speed is the highest. Makes sense? The higher speed, like the rolling resistance, may not seem all that much at first glance, but really makes a difference in longer rides.

Stability

Yes, 29-inch mountain bikes edge over the competition even in terms of stability. As we know, mountain bikes need to be especially stable as they are designed for riding off the road. This is also why most mountain bikes have suspension technology.

29ers have more stability due to their larger wheels and added traction. As more of the tires come into contact with the ground, more traction is built up, grounding you even more. What’s more, the heavier weight adds to the stability.

Things to Consider When Buying a 29 Inch Mountain Bike

Now that we know that the 29-inch mountain bike is the king of mountain bikes, we also need to know how to select the best out of 29ers. A lot of variables may come into play, the simplest one being price.

Price

Naturally, the 29-inch mountain bike, being the most technologically advanced and mainstream, costs more than its 27.5 and 26-inch counterparts. However, it’s not as simple as to say that all 29ers cost more than all 27.5ers and 26ers. You can get a costlier 26-inch mountain bike than a 29-inch mountain bike, though in that case the quality of the 29-inch mountain bike will be entry-level and that of the 26er being quite top-tier.

We have mentioned that the reason why 29-inch mountain bikes are more expensive than the other two adult mountain bike sizes is that more modern tech is designed for them. This means that you can upgrade your 29er whenever new quality components come, which you wouldn’t be able to do with a 26er. Therefore, even if you buy a low-end 29-inch mountain bike now, you can slowly upgrade it once you get the hang of using a 29er or once you have committed to cycling more often. You don’t have the luxury of overhauling a 26er, though.

Suspension Technology

Most mountain bikes today have suspension technology. They have suspension forks attached at the front and the back. The forks absorb shocks that inevitably occur on unpaved and hilly terrain.

Mountain bikes without suspension are called rigid bikes. It’s quite dangerous to ride off the road in hilly areas without suspensions attached to your mountain bike.

Mountain bikes with one suspension fork attached to them are called hardtails. The suspension fork is attached at the front. Hardtails are lighter than full-suspension bikes, and so are faster. But they are less stable.

As for mountain bikes with two suspension forks attached to them — one at the front and one at the rear — they are called dual suspension or full suspension mountain bikes. 29-inch dual-suspension mountain bikes are quite stable and offer a very smooth riding experience. However, they are also quite heavy due to the two suspension forks, and for the extra frame, geometry is needed to hold the forks.

In downhill climbing, it is better to use a full-suspension mountain bike. Otherwise, you’ll feel quite a lot of bumps on your back. However, when climbing uphill, the dual suspension technology may do more harm than good, as it will feel like climbing a steeper hill than you already are. In that case, locking in the rear suspension will be a good idea. Look for a rear-lock-out option when buying a full suspension bike.

Also, keep in mind that full suspension mountain bikes will obviously be costlier than single suspension mountain bikes. In fact, high-end ones will cost many thousands of dollars! For example, the best full suspension mountain bike under $4000 in 2021 is perhaps the Santa Cruz Blur C R Build.

Brakes

There are two main types of brakes: rim brakes and disc brakes. And while both have their pros and cons, we suggest you opt for a bike that uses disc brakes. Beware that you cannot switch back and forth between the two braking systems and experiment with them both on the same bike.

Rim brakes exert force on the rim of the wheels whereas disc brakes work by the means of a rotor on the hub of the wheel. Disc brakes outshine rim brakes in several areas such as more customizability and durability in weather conditions. However, they are also more expensive than rim brakes.

That said, we will consider disc brakes to be an advantageous feature in our review. But do keep in mind that rim brakes will work fine enough and will be cheaper as well. Check out the blog section for a comprehensive discussion on different kinds of bike brakes.

Rider Height

Typically, 29-inch mountain bikes can accommodate rider heights of 5’8” to 6’4”. If you are 5’6”, you can also try a 29er. Rider comfort is subjective to a great extent. But in general, people with heights of around 6 feet tall will greatly benefit from a 29-inch mountain bike rather than a 26 inch one.

Wheel size itself does not determine the appropriate rider height range. Frame height also plays a factor. For example, the typical frame height of a 29-inch mountain bike ranges from 17 inches to 23 inches. Other things like saddle height and inseam height also matter. Fortunately, the best 29-inch mountain bikes have easy seat adjustability.

Frame Material

Modern bike frames are made of aluminum or carbon. Carbon bike frames are typically only made for high-end bikes, whereas aluminum frames are more mid-tier bikes. We do not recommend heavier steel frames. Opt for an aluminum bike frame if you are on a budget.

In competitive cycling, every edge counts, and the carbon make of your 29-inch mountain bike might very well provide the edge you need. It’s super lightweight. However, it is also more prone to damage. Therefore, if you don’t care for speeds or a heavier bike, you can opt for steel frames. Aluminum bike frames provide a happy middle-ground. It is both relatively lightweight and sturdy.
