This action-filled crash happened on stage 4 of the Eneco Tour yesterday. Shortly before the finish, a rider from Giant-Shimano hit the tarmac setting off a domino-like effect involving approximately ten riders including two bikes flipping into the air.
Zdenek Stybar was one of the rider's involved in the crash and had to be taken to hospital afterwards with Velonews saying that he suffered "deep wounds to the Czech’s upper and lower lips, as well as broken teeth."
You'll want to watch this one a few times.
