The Metal Spin (メタルスピン) was an obstacle in the Second Stage that replaced the Gyakusō Conveyor in SASUKE 14.

It consisted of an array of chains dangle from a horizontal wheel that freely spins, resembling a chandelier, over a water.

The competitor must jump to grasp one of the chains, spinning the wheel to the other side. 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 proved to be one of the toughest obstacles in the Second Stage. In SASUKE 16 alone, it took out almost half of the people. In SASUKE 27 (its last tournament), it took out the most competitors than any other tournaments (10 out of 16 competitors failed on this obstacle).

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

American Ninja Warrior 4's Metal Spin in Stage Two

The Metal Spin was also used in Stage Two on American Ninja Warrior 4 to American Ninja Warrior 6, with the same position as SASUKE (as the fifth obstacle). However, on American Ninja Warrior 6, the gap between the chains and the landing platform was larger than on American Ninja Warrior 4 and 5.

Because of that, many competitors could not stick the dismount to the landing platform and failed. Only Joe Moravsky and Elet Hall could complete the obstacle and later the stage, but was replaced by the Roulette Row on the next tournament.
