There is only one rider that truly has those type of tricks on lock: Forest Bailey. Check his Too part. I bought the DVD, but I am sure Transworld snatched already givin’ (no pun intended) that Bailey is filming for their new video.
Rather than speculate via quick opinion, let’s take a scientific approach.
Did he, or didn’t he, complete the trick?
When one is challenged to this type of trick on a rail of this fashion, upon riding through each of the transitions there are 3 possible exit strategies. (4 if you count bailing like a dandy.)
1. Exit stage left. 2. Exit stage right. 3. Drop front stage.
Pausing at :55 we can see the rider has made it through each kink – successfully navigating the challenge though each kink & flat transition, and is – based on angle of the landing, personal preference, and snow conditions – making the judgement to exit right. These conditions can only be determined by first-hand knowledge. Thus, from a scientific perspective I would propose that the rider did complete the trick through the kink, and his exit. Could he have waited a moment longer? Perhaps, however I think that’s a tough judgement to make without first-hand knowledge of the rail and based on the conclusion above I don’t believe it’s necessary.
To the issue of whether this is a Double, Triple, or Quad kink rail. Pausing at :35 gives you a great perspective on the rail.
2 panels – Kink – 1 panel – Kink – 2 panels – Kink – 1 panel – Kink – 2 panels
It would seem that 4 kinks in the rail would make it a Quad. Depth of field on the fluid shot gives an illusion of a straight rail in a couple of areas, however looking up at the rail from :35 gives you a direct view of individual kinks.
In conclusion, my scientific evaluation has determined that the rider successfully navigated the trick, and thus “Can”. Conclusions to the contrary are of course acceptable, however if you are unable to perform said trick, you may have come to an erroneous judgement about what qualifies as a successful conclusion. Thank you for your time.
