If you’re new, it’s always a good idea to go for a middle of the road product that is good for a wider range of conditions and won’t break the bank. However, if this isn’t your first rodeo, read this article carefully so you can spend your money wisely and buy the cool mtb mudguards for your bike.

What Makes a Good mtb Mudguard

The best mtb mudguards should be able to stand up to the rigorous conditions of mountain biking, while also not adding too much weight. This is why you’ll find that most mtb mudguards are made from 100% plastic.

The Right Wheel Size

Depending on the trails you’re riding or the mountain bike you own, the wheels and tires you have on can greatly differ. Because of this simple fact, not every mtb mudguard is made for every mountain bike. Before you go and purchase an mtb mudguard online or in-store, you should know the diameter of your wheels as well as the thickness of your tires.

Some mtb mudguards are narrower than others due to their features and the way they are designed to deflect mud. Having the mtb mud flap be too narrow could cause your wheels to damage the mudflap or at the very least, cause a very annoying noise throughout your ride.

Not only do you need to know the diameter of your wheels, but also the distance from the wheel to where the mtb mud flap would be installed. Depending on the design, the mtb mudguard could dip down too low into your tires, causing damage in this way as well.

For this reason, the best thing you can do is take your mountain bike to your local shop. Working with experts in person can help you be sure that you’re buying the right product for your needs while also letting a professional install it for you.

The Various Materials Used in mtb Mudguards

The majority of mtb mud flaps are made with a plastic called polypropylene. This material is cheap, light, and easy to manufacture. While it is becoming increasingly common for brands to only use 100% recycled plastic, it is not the case everywhere.

Some mudguards are made of other materials such as metal. These can add unnecessary weight and not be as flexible as plastic models. These products are usually older in design.

The Size of the mtb Mudguard Matters

Just like shoes, mtb mudguards come in various shapes and sizes. Typically speaking, the longer and wider your mudguard is, the better. However, depending on your wheel and tire size, you may want a shorter mudguard.

How Easy is the Install Process

The install process is more important than it may seem. If you’ve ever built your own furniture, you know that it is easy to put together can make a huge difference with having clear instructions and products that .

With hundreds of models of mtb face fenders out there, you can instal these products onto your mountain bike in many different ways.

Velcro

This is probably the most common version of mtb mudguards you will see. This is a great option for when you want to remove the mtb mudguard frequently when you don’t need it or want to swap it out for something else.

Velcro is incredibly common for these products because they are incredibly adjustable, and the straps are easy to replace if there is damage. Even though Velcro doesn’t always mean high-quality in most industries, here it can be. If you see an mtb mudguard that you like and it has Velcro, it might be the perfect one for you.

Zip-Ties

mtb mudguards with zip-ties are also quite common. Similar to Velcro, mtb mudguards that use zip-ties are highly adjustable and easy to take off when you want to remove the gear. While some products have been known to shift a little more when using zip-ties, this is rare and can be easily fixed with a new set of zip-ties.

Additionally, zip-ties offer a replaceable component advantage that Velcro doesn’t have. You can find high-quality zip-ties in large quantities for very little money. Further, some manufacturers and websites suggest that you can turn any mtb mudguard into a zip-tie mtb mudguard by drilling a couple of well-placed holes. For this reason, mtb mudguards with zip-ties are a bit more accessible and better for mountain bikers who are constantly making changes to their bike or gear.

Nuts and Bolts

This is the strongest form of mtb mudguards. This form factor without a doubtis going to be the most reliable option. However, there are some downsides. First of all, the install process can be tricky. Some products come with their own tools and screws. This can mean that losing a screw or the tool can mean it’s hard to repair the product in the future and may mean you have to fully replace the product.

Best Mudguard for the Worst Conditions

Brand: CRUD XL Fender

This mtb mudguard is a new design that features high-tech solutions to some common mountain biking problems. This mudguard features a tool-free installation process that claims it is compatible with any type of bike suspension fork.

The features of CRUD XL Fender mudguard:

The clamp works by using 6 heavy-duty O-rings that are stretched around the bike fork legs and looped back onto the mudguard. Further, the arms of the fender are protected with a neoprene coating that mitigates some of the effects of wear and tear on the product and the bike.

This mudguard used by high-caliber materials and engineered to an exciting degree. However, because of all these perks, the mudguard is quite heavy, weighing in at 195g. Despite its above average weight, the mudguard is sure to stay in place and not wobble.

This mudguard has stood up even to the most rigorous of tests. After heavy use, reviewers claim that the product has not cracked or deformed in any way.

One unique feature of this product’s design is its soft nose. Near where the mudguard connects to the fork brace, this flexible nose will act as a trap door for mud to escape.
