It's not as pretty as the $85 fender from OW or super-sexy like the magnetic carbon fiber fender, but for less than $5, some of you will probably enjoy this DIY fender :-)
Goal: Create a OW fender that I can take on/off easily and stick in my pack
Why: I just LOVE that big tire, and I want to see it when I ride. Yet, I want a fender when it's wet (I have the $85 fender from OW).
Price: $5 (for 2 fenders!)
Time: About an hour
Result: Super light weight fender, that I take on and off in seconds & easily stuff into my backpack.
The key component here is a flexible piece of plastic big enough to be a OW fender (24x45cm, 9.5x18" or longer) and stiff enough to support itself without rubbing the tire. It turns out that a A3 clear book is the right strength & length - and comes in blue to boot. Just trim it to the width of the OW. I bought this at Seiyou (Japanese Walmart) for $5.
Next, unscrew the fender screws a bit...
You'll be cutting & folding the corner of the plastic to fit under this screw.
Here's a side shot.
It will look like this...
You may need to fiddle with it to get the cut depth right, so the fender doesn't hit the tire. I bent the end which goes near the sensor pad to get the best angle.
To install, slide into the end, insert plastic under the screws. I don't tighten the screws, because I want to be able to pull it right off, but you can tighten them if you like.
Attach the other side... and you have a fender. Cut nice curves in the sides if you choose..
Bonus - if you need a little case to slide your fender into when it's wet, the A3 clear book has 20 of them built in :-)
Have fun in the water!!
