Besides protecting you, the mudguards will also protect your fellow riders (when cycling with your friends) from getting sprayed.
On top of it all, these fenders will block debris from getting into the moving parts of your bike and causing havoc while keeping your bike cleaner.

What To Look For Before Buying?
The biggest reason why most cyclists end up spending their money in the wrong mudguards is that they don’t know how to choose the right one for their bikes.
There are some KEY aspects that we associate with the best mountain bike fenders. And if you can focus on these features during your purchase, you’ll end up with just the perfect fenders for your mountain bike.
These features include:
Type of Fenders
The FIRST thing you should look for in a fender is what type of bike is made for.
Many cyclists make the mistake of thinking that all fenders can be fitted on just any bike. But the real truth is that mountain bikes come with their specific mudguards which are characterized by more robust construction to enable them to hold up to the harsh terrains, debris, sticks, rocks, etc., which can easily damage it.
Once you’ve confirmed that the fenders you plan to buy are mtb-specific, you can then go ahead and check other crucial features below…
Front or Rear Fender?
Would you like to install both the front and rear fenders or just the rear fenders only?
Most bikers prefer installing mud guards to the rear only. Whether to install both rear or just the rear one is a personal preference.
If you decide to go for both fenders, we recommend you to look for fenders sold as a set to ensure uniformity on your bike (buying a set is also cost-effective in most cases). You should also ensure that the front fender isn’t long enough to block your view of the front wheel.
As for the rear fender, we recommend you to go for models meant for fitting on the bike seat post. Such fenders offer you sufficient clearance for limited resistance and to prevent jamming.
Besides, the seat post fenders are easy to install and can fit bikes with different seat post/tube diameters (though it’s always important to check the manufacturer specifications on seat post fitting).
Another essential thing to consider when looking for a mountain bike fender is whether it will work your specific bike size.
Remember that MTBs come in varying sizes. The manufacturers usually indicate the bike sizes to go with their products. Whether your bike is 26”, 27.5", 29", or comes with fat and plus size bike wheel sizes, make sure you get corresponding fenders.
Be sure to check the length of the fenders as well—the longer the fenders, the more effective they are at keeping water and debris from reaching your face and back.
We’ve already stated that mountain bike mudguards generally come with durable construction…but it’s always advisable to confirm the durability of the guards you want to buy.
Most of the top-rated fenders are made using durable plastic materials like polypropylene, polycarbonate, etc., whose sturdiness and toughness enable them to retain their shape and form ride after ride.
Despite the toughness, the mudguards should remain lightweight to ensure they don’t add unnecessary weight to your bike which can directly affect your cycling experience.
The material should also be flexible so that you can freely turn it into any shape and for easy installation.
Ease of Installation
Lastly, make sure you buy mudguards that are easy to install. You should be able to fit the fenders on your bike without hiring a professional.
Most of the MTB fenders on the market today come with a clip-on design which makes them extremely easy to install, without the need for any tools. The manufacturer should also include zip-ties and instructions set to make them easy to install.
An additional advantage of clip-on fenders is that you can easily remove them from your bike when transporting your bike or when the weather is fine.
If you go with the bolt-on fenders, make sure you have pre-drilled holes on your bike for hassle-free installation. In most cases, the bolt-on guards are not easy to remove and are regarded as permanent.
Can You Make Your Own Custom Mudguard?
You can make your own custom mountain bike mudguard using cheap and readily available materials.
Whether you want to save a few bucks or you’re a DIYer looking for a fun project to work on, we’ll show you how you can make a fully functional fender (customized according to your preferences) from scratch.
What You will need:
Cutting the metal
Cutting the metal should be easy since the metal piece comes with the right width. You’ll only need to cut the length. Create a paper stock that matches the length of the fender you wish to make and lay it over the metal to mark where you should cut to get the correct length.
If you’ve got a 20-inch wheel, you’ll need to cut a 30”long rear fender; the remaining piece will be ideal for making the front fender.
Drilling the metal stock
After obtaining the right length, the next thing you’ll need to do involves drilling the metal piece to obtain the bolts and wire brace holes that’ll help you secure the mudguard to your bike frame.
Again, using a paper template will help you easily mark where to drill the holes; you can use a marker or masking tape to mark where the holes will be drilled.
When you’ve drilled all the holes, add mounts by measuring approx. 3-inch up from the bottom and then make a line perpendicular to each side. Measure about ¼-inch from outside edge on the two sides of the line. Repeat this until you create marks for the 5 holes.
Filing and bending into shape
As you’ve already noted, the aluminum stock comes with sharp edges which you’ll need to file to ensure your own safety. Sanding the rough edges will also enhance the fenders’ smoothness. Then, you can bend the metal into place using your own hands (nothing hard here).
Now thread the wire braces through the two holes you created earlier on the inside of the aluminum piece and then wrap them around fender’s top edge. Bend the wires at the bottom into loops and secure them to your bike frame, and secure the fender with a ¼-inch screw. A simple curve on the aluminum will work.
The process might take up to an hour, but you’ll surely love the results and the amount of bucks it’ll save you.
Check the video below on how to come up with something similar to what we’ve just discussed above.
Alternatively, you can make a fender out of a simple 2-liter plastic bottle. This is a cheaper and easier one as explained in the video below:
Don’t let the rain or the winter weather stop you from enjoying cycling your mountain bike.

Besides, the mudguards will also stop the same elements from splashing onto your friends' faces if you’re group-cycling in the wet weather.
