This is a "Chinese" ollie (also called crack nollie).
If you've tried one before then you know the deal: it's an easy trick to do mediocrely, a relatively hard one to do well (i.e. get any kind of height from) and is basically impossible to do over stuff, into grinds or to flip your board from.
The reason why we like these fiddly little tricks so much is that to the untrained eye they look like nothing, but to "those who know" they are are just as impressive as any brave handrail stunt. Just try getting your board even a few inches off the ground without popping your nose (or tail) and you'll understand why we deemed the tricks in this list worthy of their own appreciation post.
Parallel's buttery ground and tiny cracks make it ideal for "Chinese" ollies, there's no doubt about that, but that doesn't mean any of the stuff in this edit is even remotely conceivable. Especially not nollie flipping into a back tail without popping your nose...
The problem with doing these down gaps is that it's hard to film them in a way that does them justice. You'd almost need two angles like here but HD and with even more slow-mo to really tell that the tail doesn't hit the ground. Which is a shame because I can't think of a more terrifying trick (especially fakie) to try down a big set of stairs...
This one's rad because it's out of a mini kicker rather than a crack. Not sure if that actually makes it any harder but it looks sick. Plus the clip serves a good reminder that Oscar can do anything he wants on a skateboard. Dude's as good at switch heelflip back tails as he is at backside bonelesses.
The cheeky ones
These two are in their simplest form, but imagine the pressure you'd feel when doing them in the middle of ridiculously tech lines like these? Plus how bummed would you be if you did a really shit one when everything else in the line was perfect? The risk kind of outweighs the reward if you ask me... That being said doing something that you are used to doing casually when you are cruising around, in the middle of a line that's driving you mad could be a good way of tricking yourself into relaxing.
This ones incredible. There's such a long way to go when you look at that microscopic crack, yet he glides over those stairs effortlessly.
Sylvain's skating is all about fiddly tricks that are a lot harder than they look, so discovering that he could boost "Chinese" nollie flips like this (from Nozbone's Café Clope) was hardly a surprise. That being said it was executed incredibly well...
Not the hardest one in this list but something about it really makes you want to go out and feel that weightlessness for yourself.
The Chinese Nollie Heel
Since looking for "Chinese" flip tricks is probably one of the nerdiest skateboard-related activities ever, we thought it would make sense to end this article with the fruit of one of our many random google searches on the subject: Adam Shomsky. As you can see Adam is a grown man that has devoted countless hours of his life to making flatground tricktips for his youtube channel. Those of you who find pleasure in the social aspect of skateboarding may find the idea of this poor guy filming himself repeatedly crashing into a crack a little sad but we think he's rad. Plus apparently this is the world's first ever crack nollie heel...
