In a video that will have you biting your nails all the way through, a daring cyclist is seen cruising down one of the steepest rock rolls on his bike. <br /><br />Making the clip even more intense is the sound of Dylan Crane's (the subject) heavy breathing as he carefully glides across the narrow surface and approaches the downslope.<br /><br />And then comes the highlight of this footage, which shows Dylan just zapping down the track in an effortless but chill-inducing manner. <br /><br />"This is the 10-story tall, near-vertical sandstone rock roll first pioneered on a bike by Kenny Smith and recently done once again by me on my Propain Tyee," the subject shared with WooGlobe. <br />Location: Utah, USA<br />WooGlobe Ref : WGA567928<br />For licensing and to use this video, please email licensing@wooglobe.com
