Two-time Olympic snowboard gold medalist and multiple X Games gold medalist Shaun White has mastered a new trick that has eluded him since 2009: the double alley-oop backside rodeo.

“It’s like doing a reverse Gainer. You’re running forward and doing a backflip or going backwards and doing a front flip,” White said in an interview with ESPN. The trick’s off-axis spin makes it incredibly difficult to land, which is why it has never been stomped in competition before.

Last February, White and his long-time sponsor Oakley set out to change that by holding a private halfpipe session at Northstar-at-Tahoe in California. White first attempted the trick in a foam pit until he felt confident he could land it on snow.

Now as the professional halfpipe season draws near, White and Oakley released a video of White stomping the trick, which shows he has it on lock.

According to ESPN, there are only two other riders, Danny Davis, and Elena Hight, who have ever landed the trick, and each did so after White. So will the double alley-oop backside rodeo be the ace in Shaun’s back pocket–the card he’ll play when the competition edges too close this season? We’ll have to wait and see.
