'Don't try this at home' says professional MTB stuntman...

A cyclist has released a drone video showing him taking on a virtually vertical rock face on his mountain bike.

Polish-born Michal Kollback visited Sedona, Arizona and after a few days’ consideration, let much of the air out of his tyres for added grip and took on the death-defying feat.

"Conquering this ride was all mental," he told the Huffington Post. "I was confident with my skills and knew I could execute it. The key was to block the out the scary thoughts about the potential danger, so I just focused on the trail and not on the terrifying space around me."

Posting the video to Youtube, he described it to his Instagram followers as "one of the scariest things i have done on a bike."
 

 

"I live for thrills like this, and I would have tackled this line whether it was filmed or not," he added.

"The drone was a bonus, and [videographer Marshall Mullen] did a great job capturing the moment. However, it's not for everyone, so I strongly advise inexperienced riders against trying this line."

The 30-year-old daredevil makes one journey across the rock face of the famed White Line before also completing a journey back.

After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur.
