Hello,

With my daily commuting way going through a forest that is getting quite
muddy, and that will probably get worst when it starts snowing, I have
noticed my regular mudguards do not protect me completely.

I know some people are completing their front mudguard by mounting some
additional plastic foils on the bottom. I am looking for reports or
tutorials for this, would you happen to know about this?

I assume you're talking about what we call "mud flaps," like this:

I've used them almost forever and have made them out of several
different materials. Most of mine were cut out of the sides of
polyethylene gallon jugs. Cylindrical jugs work better than the vaguely
cubic shape of milk jugs. I now have more elegant ones I cut out of EPDM
rubber sheet about 1/16" thick. Mine are shaped with a sort of flare, so
the lower portion is two or three times as wide as the fender.

I fasten mine to a 1/4" hole drilled in the bottom edge of the fender. A
nylon screw (rust free) goes through the hole in the mud flap, then
through the fender from the inside. A wing nut screws down on the
outside of the fender, so I can easily remove the flap and toss it in
the handlebar bag when its not needed. (That's for aerodynamics!)

BTW, I learned the hard way that if you're riding with fenders in muddy
conditions, you need lots of clearance between the tire surface and the
fender's inside surface. But you probably know that already.
