It is a tensioner set to make the frame for the external transmission proposed by Grange, a brand developed by Tokyo Sanes, into a single speed bike.

Tensioner 2 is a simple chain tensioner that is fixed with a quick nut and a rear derailleur pedestal. Also, unlike Tensioner 1, it has a built-in spring, so it has a mechanism to adjust the chain tension with a pulley.
