Scottish trials ace Danny MacAskill has posted a video to Facebook showing him riding on a slackline – and it’s left some of his million or so followers on the social network slack-jawed in amazement.

Let’s face it, riding along a thin, unyielding surface – the top of a set of railings, say – can be difficult enough, but add in the effect of the weight of rider and bike on the slackline and it’s something else altogether.

The clips have even earned MacAskill an invite to the Stuttgart headquarters of slackline firm Gibbon, with the company’s Patrick Stern saying, “We’ll hook you up with gear!”

There’s no way of knowing whether or not a slackline will feature in MacAskill’s next full-length video.

It would have to go some way, however, to top this effort from multiple UCI trials world champion Kenny Belaey that emerged a couple of years ago, with the riding a slackline above a dropof 100 metres between two peaks in the Alps.
