Petrohrad has maybe the worlds biggest dyno called The Czech Chuck.

A friend of us pointed on an interesting video showing the biggest dyno at Petrohrad and maybe one of the biggest dynos ever.

The jump did David Gater who thought that it could be one of the biggest dyno in the world much bigger than well-known dyno Rainbow Rocket in Fontainebleau.
David didn’t give the grade but he measured it and he claims that it has length 260 cm.
Quite impressive.
The dyno is in Mlynsky vrch area on the stone called Placička (number 818 in the topo) and has a name The Czech Chuck .
