VoulVoul Racing Team 2013: Fast and Slow

 For that season, the VoulVoul Racing Team comes with new ambition, new sponsors.. and a new young pilot: Marine Cabirou. She joins her brother Rudy who rides with that team since the last season. With the other pilots, Romain Goulesque, Christophe and Olivier Afflatet, Jean-Didier Payet, Guillaume Gravoulet, Sacha Malta, Teddy Perrier and Patrice Afflatet (Manager), they will race for the regional cup, the national cup and the world cup (for Rudy and Romain).
They all ride on the La Grand Combe track in Gard, maybe the best track in the region... or beyond !
From the title, you will see that this video shows speed and slowmotions !

 Who makes that direct mount stem in the intro ?
