For real? This obstacle looks really amazing to me. Greg Hermann will show us what is it to fingerboard on this fantastic piece of concrete in this video. It looks like some secret material, something similar to harrier or stuff like that. But the difference is in that small pieces of glass in the grind. Sounds pretty fantastic when Greg grind on it. It must be really awesome feeling to fingerboard obstacle like that. Whole video is really good and Greg can ride it like a boss, am I right?
