Mountain biking can be an extreme sport where riders can experience an array of riding conditions on any given day. Depending on geographic location and time of the year, rain (or snow melt) can produce sloppy conditions that can add an additional element of adventure to the ride. Selecting the right mud guard, or fenders, for your bike can reduce the amount of mud that you (and your bike) will be wearing at the end of the day. And unlike the more permanent style of fenders that your childhood bikes might have possessed, most of the newer versions can be added and removed as conditions dictate. As with any bike component, there are an array of options and finding the right one for your bike or riding conditions can be slightly overwhelming.
Don’t let the mud drag you down! Here at The Adventure Junkies, we pride ourselves in helping you choose the best gear for your next muddy experience. In this guide, we’ll help you pick the best mountain bike mud guard so you can stay relatively clean and mud free on your next foray onto the trails.

The unique design covers a large area providing more protection for you and your bike. As a bonus, this set is less than some single products in this guide.
THINGS TO CONSIDER BEFORE BUYING MUD GUARDS
Unlike road riding, mountain biking takes the rider off-road where they are bombarded by an assortment of substrates. Certain geographic regions are more prone to muddier conditions and riding in these conditions can spray the bike (and rider) with mud, water, and loose pebbles. Over time, this grime can take its toll on your bike and the components. And while it’s important to clean your bike after each ride, preventing some of the material from reaching your bike is part of the battle.
Additionally, utilizing mud guards can have an additional benefit of protecting those riding with you from the spray that you’ll kick up if you’re the lead rider.
COST
Cost is not a primary concern as most mud guards in this guide are inexpensive. Even the most expensive model included here is a set (includes front and rear). The true benefit may come from protecting the other parts of your bike from the grime that can wear out other more costly components, thus reducing the lifespan of more costly items.
SIZE
All of the mud guards in this guide are designed for mountain bikes and are relatively low profile due to conditions that will be encountered when riding on trails.
FEATURES EXPLAINED
POLYPROPYLENE
Polypropylene is one of the most commonly used plastics in the industry.
COMPOSITE
