Box One™ Chain Tensioners are extruded then CNC-machined from 7075 aluminum for an optimal balance of strength and weight. A minimalist design adds style while reducing their overall mass. Laser-etched graphics that include wheel position guides and two 10mm mounting holes ensure perfect adjustability on most frames every time you remove and replace your wheel.
