The Metal Spin (メタルスピン) was an obstacle in the Second Stage that replaced the Gyakusō Conveyor from the past thirteen SASUKE tournaments.

It consisted of an array of chains, dangling from a horizontal wheel that spun freely (resembled a chandelier), over a water.

Competitor must jump to grasp one of the chains, and then spun the wheel to the landing platfom. Starting in SASUKE 15, the chains were given bungee cords, causing the chains to stretch and requiring competitors to have a strong grip to prevent the chain from slipping out of their hands.

It was the only Second Stage obstacle to be retained after Nagano Makoto's kanzenseiha. However, it was modified with a longer run-up, but the actual obstacle was also further from the platform than the previous versions.

This obstacle was proven to be one of the toughest obstacles in the Second Stage. In SASUKE 16, it took out almost half of the competitors who attempted the obstacle (including Akiyama Kazuhiko, Kobayashi Shinji, and Paul Hamm). In SASUKE 27 (its last tournament appearance), it took out 6 out of 16 competitors who attempted it (including 3 American competitors: Travis Rosen, Travis Furlanic, and Brent Steffensen).

In SASUKE 28, this obstacle was taken out in favor of the Backstream.

The Metal Spin appeared in Stage Two from American Ninja Warrior 4 to American Ninja Warrior 6, with the same position as SASUKE (as the fifth obstacle). However, unlike in SASUKE, the distance between the starting platform and the array chains was smaller, and the array of chains was placed lower (resulting competitors could grab the middle of the chain instead of the lower end).

On American Ninja Warrior 4, 3 competitors (Paul Kasemir, Brent Steffensen, and Derek Nakamoto) could reach this obstacle, and Brent Steffensen was the only one who could complete it, and later finished Stage Two. On American Ninja Warrior 5, 8 competitors could reach this obstacle, and only one competitor (Andres De La Rosa) failed.

On American Ninja Warrior 6, the gap between the array of chains and the landing platform was made larger than on American Ninja Warrior 4 and 5, requiring competitors must swing the chain to reach the landing platform. As the result, many competitors could not stick the dismount to the landing platform, got hung up on the chain, and forced to fall into the water (e.g. Travis Rosen, Andrew Lowes, and Chris Wilczewski). Only Joe Moravsky and Elet Hall could complete the obstacle, and later finished Stage Two.

On American Ninja Warrior 7, the obstacle was replaced by the Roulette Row.
