KH20 pedals?

I just received my new KH20 08 and I was wondering if the plastic twisted pedals are mainly for indoor riding, or do some people use them outside? I would think that they would get worn pretty fast on concrete, rails etc.

i use plastics for everything except trials and muni. plastic will do fine on rails. so yeah, go plastics.

The plastics are great for all kinds of riding. I’ve been on the same pedals for almost half a year now.
