The best deal on this quality dual-bearing spring chain tensioner!
Not only is the pulley fitted with a sealed bearing, but the lever is also on a sealed bearing as well. This sure beats relying on bushings and spacers/washers like the competitors use.
Keeps your chain properly tensioned at all times. This prevents chain binding, derailing, and excessive chain wear. Fits 2 stroke and 4 stroke motorized bicycles alike.
NOTE: some pulley arms are silver and not black like in pictures. These will function exactly the same, and there is no other difference besides color.
