While mountain bike mudguards are not going to up the cool factor of your bike, they can definitely be helpful at keeping you and/or your bike clean and dry. I have already made a simple front fender, but I needed something that could be used at the rear as well. While it may not protect the rider much (at all), it will offer a dropper seat post and rear shock (and pivots) some protection against dirt and mud. Additionally, it will also keep your rear mounted water bottle cleaner, because who likes drinking from a filthy bottle? So it works for both full suspension and hardtail/rigid mountain bikes. Why not for other types of bikes as well? The best part is that the whole thing weighs less than 20 grams. That’s a very small weight gain for all the benefits.
Here’s how to make your own.
Required materials and tools
What you will need for making these mountain bike mudguards are:
- Flexible cutting board or other flexible plastic
- A compass will come in handy
- Scissors and a sharp knife (a hole punch can be useful, but I didn’t use one)
- Some tape and zip ties.
Note that these measurements need to be changed depending on the width of the tires and tire clearance. I made mine as small as possible for 2.25″ tires, so feel free to size it up to make it fit your bike better!
Also, the design may/may not work for full suspension frames. Test it out first with the paper template to avoid wasting material.
The mudguard is very straightforward to make. If you have got a printer, just print out the PDF-file, cut it along the lines, stick it on the plastic, trace it, and cut the mudguard out. If you haven’t got an access to a printer it’s very easy to draw one too by yourself. Just check the measurements and draw it on a piece of A4.
Remember that you only need to draw one side of the mudguard on paper. Once you’ve drawn it (don’t forget the holes for zip-ties), fold the paper along the centerline and cut it out.
Next, cut the template out following the lines.
At this point, it’s good to check the fit on your bike. If it fits then stick it on the plastic (tape helps), trace along the outer edges and holes and cut out the mudguard. You can use a hole punch for making the holes but in my opinion, a sharp knife will do the job just as well.
Now it’s just a matter of using some zip-ties to secure it in place and going on a test ride!
