The Chain Reaction (チェーンリアクション) is the first obstacle of the Second Stage from SASUKE 7 to SASUKE 17. It consisted of two perpendicular zip-lines. Each zip-line has a chain hanging from it by a single point. Competitors must grasp the chain on the first zip-line, ride down a 9.5 meter-long track and switch to the next chain in midair. Once on the second chain, the compeitiors must kick off a wall to travel along the second track (7.5 meters long) to a landing platform at the end. Competitors are required to wear gloves (for safety reasons) when holding the chains, which they must discard prior to reaching the Spider Walk. This particular rule came into play when Yamada Katsumi forgot to take off his gloves during the Spider Walk in SASUKE 12. After Nagano Makoto's kanzenseiha, it was replaced with the Downhill Jump. Starting in SASUKE 13, the producers were given a new wallpaper for the obstacle. This SASUKE 13-17 wallpaper was also used on the Downhill Jump. 5 people failed it.
