How to Choose Good Hardtail Mountain Bikes

A lot of people tend to get confused when they hear the term “hardtail.” Hardtail bikes are usually compared to full-suspension bikes because they only have a single fork. As for the latter, they have a shock at the rear in addition to the suspension fork up front.

Shape, material, suspension, brakes, and wheels are just some of the factors you need to consider before buying a hardtail mountain bike.


Slack, low, and long are the adjectives you usually hear whenever frame shape or geometry comes to mind. Of course, there are other considerations like the length and height of some crucial sections around the bike.


Slack refers to the angle of the head tube. A slack angle greatly contributes to downhill rides. However, a slacker angle at the head tube can significantly affect your performance on other activities like hill climbing.


The concept of lowered bikes doesn’t necessarily mean that they have smaller wheels, but it indicates that the bracket at the bottom is lower than or level with the axles. This is the preferred type of frame geometry for technical riders.


Long bikes show that the gap between the wheel axles is longer. Simply put, the length of the wheelbase is increased. This greatly contributes to the stability of the bike at high speeds. A longer wheelbase also gives better control on steep trails.

Other Factors

Additional aspects to consider when thinking about the frame are the length of the chainstay and the standover height.

The frame’s component between the rear wheel axle and where the crankset sits is the chainstay. The length of the chainstay contributes to the bike’s overall stability when moving. A longer chainstay means better stability.

Meanwhile, the space between your crotch and the top tube is the standover height. This space is essential to allow the rider to move around on the bike while riding.


Steel, carbon fiber, and aluminum alloy are the materials commonly found on hardtail MTBs.


This material was already used for the earliest groups of mountain bikes massively produced for people around the globe. Mobility may be affected due to its weight, but it has more strength than the rest. Shock absorption is tested and proven with steel bikes. Being reparable through welding is also a huge plus.

Carbon Fiber

Despite being the lightest among the frame materials, carbon fiber is extremely sturdy for rough trails. Carbon fiber sheets are flexible and stiff, so it can be strategically layered onto different parts of the frame to cater to the needs of the rider. However, more stiffness on the frame also means it’s less likely to dampen vibrations.

Aluminum Alloy

The first substitute for steel bikes, aluminum alloy is lighter and cheaper. Aluminum is as durable as steel and also less stiff than carbon, meaning it can handle rougher trails. Even though steel usually lasts longer than aluminum, proper upkeep is already enough to keep the latter in tiptop shape.


Here are the things you need to know when it comes to suspension forks:

Short-travel suspension

Used for cross-country and trail mountain bikes, the short-travel suspension has a travel length of 120 millimeters or less. This type of suspension fork is designed for all-around riding. They’re also best for hill climbing and pretty decent for downhill rides.

Long-travel suspension

With suspension travel of 120 to 200 millimeters, this type of fork is designed to go down on rough trails at higher speeds with excellent control and also perform decently on uphill trails. Having a longer front travel means better performance for downhill riding.

Diameter of the Seat Tube

The size of the seat tube contributes greatly to comfort, especially during long rides. The best seat tube diameter is about 27.2 millimeters. It’s the perfect size for versatility in terms of terrain. It’s obviously lighter as well.

On the other hand, some riders who love the thrill of downhill riding prefer 30.9 or 31.6 millimeters for comfort. A large diameter means more weight, but it can also accommodate an adjustable dropper seat post.


When it comes to brakes, it’s important to understand the major types and the ideal rotor size for your needs.


There are three types of brakes: coaster, rim, and disc. Coaster brakes are the old-school type which relies on back-pedaling to clasp the rear wheel.

Meanwhile, rim brakes have two pads near the wheel in order to hold the rim and slow down the rider. However, it’s not exactly recommended for most users because of its minimal stopping power.

Lastly, disc brakes come in two types: hydraulic and mechanical. Mechanical disc brakes are operated by cable, similar to rim brakes, and are cheaper and easier to maintain. Meanwhile, hydraulic systems use brake fluid to transmit the stopping power to the caliper. They’re more expensive but more efficient.

Rotor Size

The stopping power of brakes isn’t just about the system used but also the size of their rotors. Rotors have four diameters to choose from: 160, 180, 200, or 203 millimeters.

The larger the rotor, the stronger the brake is. It also lessens the possibility of overheating. Bigger rotors, however, are heavier and may affect your mobility.


Size and material are the most important factors when checking a mountain bike’s set of wheels.


Nowadays, mountain bikes have two wheel sizes to choose from: 27.5 and 29 inches. The basis, mostly, for choosing the wheel size is the size of the rider. The taller the rider, the larger the wheels should be.

A 29-inch wheel is great for riding tough downhill trails at maximum speed but not exactly the more responsive and flexible one. Meanwhile, 27.5-inch wheels are ideal for sharp corners since they’re more flexible than 29ers.


The material used for the rims is another factor in choosing wheels. The two common types of rims available in the market are aluminum and carbon.

Carbon rims are stronger, stiffer, and lighter than aluminum. The stiffness of carbon rims contributes to faster acceleration but can be bad for rough downhill riding as the material isn’t really effective for shock absorption. Cracks on carbon rims are irreparable.

Aluminum rims, on the other hand, have better shock absorption and a higher chance to just get dented rather than crack. They’re heavier and cheaper than carbon rims but better at dealing with bumps.


Among the high-quality hardtail MTBs we’ve discussed, the Diamondback Bikes Sync’r Mountain Bike has caught our attention the most. It’s comfortable, versatile, and convenient, unlike most bikes that perform perfectly but have poorly designed seats and are a hassle to set up. Despite not being the best option for shorter riders, it can be used on various terrains no matter your riding style. It’s also pre-assembled and compatible with tubeless wheels.

If you’re planning to search for more options, keep in mind these factors: geometry, frame material, suspension, type of brakes, rotor size, and wheels. Aside from making sure that the geometry of the bike ultimately leads to a hardtail, check the durability and versatility of the frame, the level of shock absorption from the suspension, the efficiency of the brakes, and the maneuverability of the wheels.
