How to Choose Good Single Speed Mountain Bikes

Whether you are looking for an upgrade or a starter bike for your return after a long time of pause in biking, the selection for the best single speed mountain bike remains a challenging task. With continuous upgrades and innovations on mountain bikes, it can be overwhelming to come up with a decision on what model to take. So to help you find the model with the best specifications to suit your needs, we have prepared a useful buying guide that you can use.

While speed is important when looking for a bike, considering other factors proves to be your best approach for this one. Let’s take a look at the things that you can’t miss when making a purchase. These can give you the ride of your life.

Be Specific with Your Riding Style

There are different types of bikes and riding styles that you can choose from. If you are looking for rigid or hardtail bikes that are simply made with one gear, then a singlespeed mountain bike is the right choice for you. This usually requires minimal maintenance because it does not have shifters and derailleurs. Plus, it can be used in different settings such as off-road, singlespeed XC races and even for regular cruising and commuting around town.

Check Out the Frame

A mountain bike’s frame can be crafted with different kinds of materials. A bike’s frame can be made with aluminum, steel, titanium and carbon. Each has its own strengths and weaknesses. Aluminum is ideal for those who want a lightweight and strong build. This does not rust, it is responsive, pleasant to look at and definitely a more economical option than other types.

On the other hand, bikes made of titanium, carbon and steel are definitely more durable. Among the three, steel is the most expensive as it combines sturdiness and reparability while sporting a lightweight build. As for carbon and titanium, these are leaning towards the more expensive side as these are usually found on models that are high-end and more sophisticated looking.

Carbon is super-light weight and has excellent anti-corrosion properties. This is strong enough to endure constant use, however, it may not be able to stay in good structure during powerful clashes. As for titanium, it is as strong as other materials and it features a natural look that needs no painting to look presentable. The only downside for this one would be its cost as this is the most expensive among all the options.

Get One with Excellent Suspension

While tires are built to give you extra cushion while riding, it is also a good decision to get one with excellent suspension forks or front and rear shocks. These are capable of remaining intact even when faced with a lot of bumps while riding. Trail riders invest on bikes that have effective suspension because it absorbs the shocks in the most challenging trails. Plus, this gives your body a lot of benefits because it lessens the stress and beating you go through during the ride. So if you have neck and back issues, keeping this on top of your checklist are necessary.

Mind the Brand

A bike can sport various brands for its components. A few manufacturers to take note of would be Shimano and SRAM. These two produce first-class components that range from brakes, crankset, drivetrain and more. These brands are known for a reason, hence, it pays to invest in bikes made of these because most of them have been tried and tested by a lot of bike enthusiasts. It is also important to go for a brand that caters to your needs and level as a biker. Some brands are great for entry-level and beginners, while some are intended for professional and race-oriented users.

Get to Know About Its Stopping Mechanism

Bikes can have rim or disc brakes to trigger the stopping mechanism. Rim brakes are more on the traditional side and it functions by rubbing on the rim to slow down and stop. However, the downside for this type would be that it can cause damage to the rims overtime. And it is not too ideal for those who often ride on wet and muddy terrains because it wears and tears the parts faster than usual.

On the other hand, disc brakes function through a rotor that is attached to the wheel’s center. When you grip to stop, your bike responds accordingly. This is a good choice if you want to avoid rim damage as you use it. A lot of people go for disc brakes because they require less maintenance as compared to the other type.

Wheels Matter

Whether you are aware of it or not, wheels play a huge part in giving you the ride you want. The wheels mountain bikes have are definitely stronger and more durable than others because it is created to endure the impact of off-road and trail riding. These are enveloped by big and fat tires to provide excellent cushioning to prevent damage to the wheels and rims. Tires also define traction and control so it is vital that you invest on those that are of high-quality.

Get the Right Handlebars

If you are a cross-country or long-distance rider, it is best that you invest on flat bars. This is because these are made to sit lower and lighter which allows you to feel comfortable during long rides. But if you plan to go up and down hill, riser bars are the best choice. These sit higher and give you a broader view and stance while riding. These are ideal for downhill riding and technical surfaces.

Fit the Seat

Apart from looking at all the other parts of your mountain bike, you also need to focus on the seat. Try it on and find one that gives you the most comfort in terms of cushioning and fit. Get one that fits your body frame properly because not getting the right one can leave you with a strained neck and back. Possible problems such as pain and numbness on your extremities can also happen if you get the wrong seat.

Choose Your Pedals

You can choose among platform, simple and flat pedals. If you want a more secure option you can get those that are equipped with straps and clips. But a rider who wants to use them will usually need shoes with cleats so it can lock onto the pedals. However, those who want to execute diverse movements such as turns, tricks and spins, getting pedals without clips and straps are recommended. It is definitely easier to perform those movements with flat, platform pedals.

Value for Price

If you purchase a bike just because it is expensive and is the latest edition, then you may be missing out on what you really need. Learning about the features and pointers to look at before making a purchase can help you determine whether the bike you are about to purchase is truly worth the price. So doing your own share of research can save you a lot of money while getting all the features you need for your desired riding experience.
