Marijn vdBergh went too hot into that curve, hit the brakes to the max sliding out.
The worst thing about that curve is that the barriers went inwards at the end of the curve. They could have solved that by going from wide to narrow in the curve in a smooth line, not with a sudden jump of around a meter that vdBergh couldn't adjust anymore to.
Crash with Buitrago at 3.9K from the finish so time loss counts.
The funny thing is that Groves thought he didn't have the win, looking behind and shaking his head. Then he saw that around the curve there was the last straight, going uphill, he recharged and overtook Molano with a last hard kick.
