These fenders are for Road 700c wheels. I put a pair on my bike fairly easily (only a little bending of the steel rods)

The instructions were printed on the inside of the cardboard that holds it all together, but weren't that helpful - basically just said to put them on and tighten the screws.

One thing that made it a lot easier - my frame has mountings to accept the screws, most new frames don't.
