That's why Red Bull Hardline is an event like no other. This long and technical course is played in a variety of disciplines, where extremely steep and rocky technical parts are combined with a 15.24 meter motocross and leap to create one of the most progressive descending trails on the planet. #MTB #redbull」3月6日 18時39分
