BOX Single-Speed Tensioners. Measurements printed on the top edge of the tensioner make this one of the the best tensioners on the market for making sure you have perfect rear wheel alignment.  No need to break out a ruler or estimate whether both sides are even by holding your fingers a certain distance apart (that never works).
