This is a super cheap way to have an indestructible mud guard on your mountain bike.
Things you will need:
Cheap plastic cutting mat ($1 at Dollar Tree) http://goo.gl/rh3oYy
Printer (to print out stencil 8.5 x 11)
X-acto knife or hole punch
Print out stencil PDF on 8.5 x 11 (landscape) letter paper and cut it out with scissors. Don't forget to cut out zip tie holes.
I added a second version of the mud guard. I extended the guard past the forks to control even more of the muck and mire. Enjoy.
You will need to print out both pages line them up and tape them together and then cut out the whole stencil. (I did this because I figure most people only have letter size paper not 11x17 or the like.)
Trace out line of paper stencil with pencil onto plastic cutting mat
Cut plastic cutting mat into shape traced onto mat. Punch or cut holes in plastic for zip-ties.
Mount mud guard onto forks. Loosely attach all four zip-ties to fork. Stating with the top zip-ties snug them up to the cross member making sure the mud guard is centered. Then snug the zip-ties on the down tubes. Then snip off zip-tie tail.
APPLY STICKERS, and go get muddy!
