The X Games is often the place you'll see someone put down a new trick for the first time, and the 2017 edition was no exception. After seeing a few quads put down on purpose-built monster booters - beginning with Billy Morgan's backside quad cork 1800 back in April 2015 - we can now, frighteningly, expect them to become the norm in contests.
Two variations of the quad were unleashed in the men's Big Air final, and naturally they secured podium spots for the riders that put them down. While they're unlikely to stoke out the 'floaty backside 180' crowd, for pure bonkersboarding check out all three medal-wining runs below.
3rd: Mark McMorris (Canada)
There are few riders that can stomp triple corks with the consistency of Mark McMorris, which goes some way to explaining why he keeps winning X Games medals. While he put down a couple of belters in the final, this time it was only enough for bronze.
2nd: Marcus Kleveland (NOR)
The honour of stomping the first quad in competition went to young Marcus Kleveland. He put down a backside quad cork 1800, a trick that may have got him the gold had it been a little cleaner. He may not have taken the top spot on this occasion, but he certainly got a priceless reaction from Danny Davis & co at X Games HQ.
1st: Max Parrot (Canada)
Last year's champ Max Parrot edged out Marcus this time round with his quad underflip, which scored one point higher than the Norwegian's quattrocorking. It's certainy not the prettiest trick in the world, but after he put down a contest NBD with authority, the judges had to hand it to Max. Both he and Marcus scored the same on their second-highest trick - just look at the laziness of that Cab triple 18 - so the Canadian took home the gold once again.
