The 900 is a 2½-revolution (900 degrees) aerial spin performed on a skateboard ramp. While airborne, the skateboarder makes two-and-a-half turns about their longitudinal axis, thereby facing down when coming down. It is considered one of skateboarding's most technically demanding tricks.
On June 27, 1999, Tony Hawk, one of the most successful vertical pro skateboarders in the world, landed the 900 at X Games V after ten failed attempts. It was past regulation time but, as one announcer said, "We make up the rules as we go along. Let's give him another try." Other skaters protested, but Hawk continued. Hawk twice landed on his board, but it flew out from under him. When he finally completed the trick, his arms windmilled and his hand barely grazed the ramp. Nonetheless, he rode away.
In his book, the 900 was the last on the wishlist of tricks Hawk had written a decade earlier. Other tricks on the list included the ollie 540, kickflip 540, and varial 720. In a 1999 interview, Hawk said he does not have "any desire to spin further." He successfully landed the trick during press interviews for the video game Tony Hawk: Ride and at the "Tony Hawk: RIDE Presents Stand Up for Skate Parks" event. In 2011, Hawk was still able to land the 900, and posted a video of the trick via his Twitter account, stating, "I'm 43 and I did a 900 today." On June 27, 2016, Hawk was again successful.
A number of opinions exist about pre-1999 900s. The most prominent of these is the argument that Danny Way landed the 900 in 1989, and it appears in an early Santa Cruz film. In 1999, Tony Hawk said:
"Well, he was shown in a video almost 10 years ago. He was really close, but he didn't make it. He came the closest by far, but they cut the video before he fell. So it may have misled some people. There are only four people who have been able to spin completely and he's one of them. Tas Pappas and Rob Boyce also have spun it, but they haven't landed it."
In May 2020, 11 year-old Brazilian Gui Khury became the first person to land a 1080 using only a vert ramp.
In 2012, Tom Schaar landed a 1080 on his fifth attempt on the mega ramp.
In August 2019, Mitchie Brusco became the first person to land a 1260 (three full and one-half revolutions) in a Big Air competition at X Games Minneapolis.
The 900 can also be attempted on a BMX bike, skis, snowboard, inline skates or a scooter. BMX rider Mat Hoffman was the first person to successfully land the 900 on film at a competition in Canada in 1989. In 2002 at X Games VIII, Hoffman took the trick a step further by landing a no-handed 900. BMX rider Simon Tabron's signature trick is the 900. In the 2007 at X Games XIII, Simon Tabron landed the first back-to-back 900s on a bike.
Because the gear of snowboarders, skiers, and inline skaters is affixed to their feet, the 900 is not considered to be a difficult trick for professionals in those sports and is performed comparatively often. 1620 and 1800 degree spins have been landed on skis, a 1620 has been performed on a snowboard as well as on inline skates, 1080 on BMX, 1080 on scooter.
