Mudguards deflect the sludge that is flung up by your tires, ensuring that your vision is clear and your bike stays clean.

Mountain bike mudguards are a type of mudguards designed for off-road bikes, but they are also commonly used for on-road cycling. In this article, we will discuss everything you need to know in order to decide whether you need mountain bike mudguards or not.

Mountain bike mudguards are beneficial for riding in wet and muddy conditions. They protect the bike's mechanics and seals from grit and block water and mud sprays, keeping the bike and rider protected and clean.

What is an MTB mudguard?

When using mudguards a rider is kept dry and comfortable in harsh weather conditions. They also protect riders cycling behind from the water and mud that is flung up.

A mountain bike mudguard is a wing or fender designed to cover the wheels of a mountain bike for protection. They shield seals and rotating bike parts from getting damaged. Mudguards also serve to prevent water and mud from flying into the rider’s eyes and onto their clothes.

A variety of MTB mudguard types exist. There are clip-on mudguards, full-length mudguards, bolt-on mudguards, downtube mudguards, headtube mudguards, and rear mudguards. Mudguards are available in different sizes to suit different widths of bike tires. When choosing a type you should consider the attachment points on your bike. For example, if your bike has eyelets you can use traditional full-length mudguards.

Should I Install Mountain Bike Mudguards or Not? Reasons Mudguards are Useful

Many cyclists wonder whether they should install mountain bike mudguards or not. We will explain in detail when and why you might need MTB mudguards.

Whether to install mountain bike mudguards or not depends on the weather conditions and terrain. Mudguards are most effective for riding on muddy roads and in wet weather. One should definitely consider using them when in a group as riders cycling behind won’t suffer the spray of water and mud flicked up by the tires.

One should consider using mountain bike mudguards for the following reasons:

1. To Keep You and Your Bike Clean When Riding in Wet Weather

One of the most important advantages of using mudguards is that they block water and mud sprays from ruining the look and functionality of your bike. Without them, mud that flings off the front tire ends up covering everything from the fork to the frame. Using mudguards will save you lengthy cleaning sessions and extra maintenance. If you are the type of person that does their own repairs check out our ultimate list of tools needed for mountain bike maintenance.

Importantly, mudguards prevent mud from reaching your face. This study, published by Cambridge University Press, was conducted to explain the prevalence of gastrointestinal disease in riders after participating in cycling events. It determined that mud splashing was the cause as mud is often contaminated with bacteria originating from animal feces and using mudguards greatly reduces the risk of infection by keeping your face clean during rides. So, whether you need mountain bike mudguards or not depends on whether you ride in muddy conditions.

2. Because it is a Requirement to Join Cycling Clubs

Using mudguards is a requirement if you want to join some cycling clubs. For example, The Warwick Lanterne Rouge Cycling Club in the UK asserts that all cyclists should fit mudguards on their bikes to avoid bothering other riders with water and mud sprays. To join their club using mudguards is one of the requirements stipulated in their riding guidelines. Some cycling events also require participants to use mudguards for health protection reasons.

3. To Protect Seals and Rotating Parts From Grit

Another important feature of mudguards like these is that they protect seals and rotating parts from grit. They deflect grit away from the wheels and any moving parts of your bike thereby preventing damage and accidents. Thus, using mudguards also increases safety when riding in dry weather when stone chippings can also be flicked up.

4. To Improve The Look Of Your Mountain Bike

Some riders use mudguards like these to improve the aesthetics of their bike. There are a variety of colorful mudguards that help make a bike stand out.

Not only can this be irritating, but it can also be very dangerous, especially when riding at high speeds. Thus, using mudguards will reduce the risk of having an accident. 

6. To Stop Water and Mud Splashes from Landing on the Cyclist's Back

Lastly, mudguards prevent water and mud splashes from landing on the cyclists' backs. This is of particular importance in the winter when having wet clothes is not only very uncomfortable but potentially dangerous. For tips to ride in the winter see this blog by SKS Germany.
