The Box One™ Chain Tensioner is a BMX race essential, extruded and CNC-machined from 7075-T6 aluminum to deliver a 20% increase in structural stiffness at a mere 69g. Featuring a unique XO Skeleton design, it provides 100% security for your rear hub, preventing wheel slip during high-wattage gate starts. With 15mm of primary adjustment and dual 10mm mounting holes, it offers a total adjustment range of 45mm to ensure perfect chainring and cog alignment. This tensioner acts as a critical shield for your frame dropouts, absorbing the torque generated when you pull maximum leverage against your bars and grips.
