here a picture of my pedals ... there replica Carbon Fiber with a mesh insert. I can't remember who there by off the top of my head.
Most pedals are simple to install ... basicly they have medal tabs which wrap around your existing pedals and then usually one bracket which you place behind your pedal and tighten.
This keeps it in place because you are tightening against the rubber on your pedals compressing it.
My pedals also had a little lip on them which fit on the bottom of the stock pedal to properly line it up.
They should all comes with simple directions.
