Adjusting chain tension is quick and easy with the Box Three Chain Tensioner. With a single hole "lollipop" design, these tensioners reduce weight and help keep your rear wheel locked in place.
Box Two Chain Tensioners let you dial in your chain tension so it's just right. Two mounting holes provide room for ample adjustment on most frames. When used properly, Box Two Chain Tensioners help protect frame dropouts and keep your rear wheels locked in place where they should be. For use with 10mm axles only.
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. When used properly, Box One tensioners will protect your frame dropouts and hold your rear wheel in place. Keep in mind, however, they aren’t indestructible (neither are your dropouts). Install these lightweight chain tensioners with care and leave the 15-inch breaker bar in your toolbox.
