The Box Two™ Chain Tensioner is the go-to solution for riders seeking 100% drivetrain reliability and a locked-in rear hub. CNC-machined from 6061-T6 aluminum, these tensioners offer a 30mm adjustment range via a dual-mounting hole design, ensuring your chain remains taut during explosive gate starts. By providing a rigid physical stop, they protect your frame dropouts from the crushing force of high-torque crank rotations. At a lightweight 55g, this set minimizes bulk while maximizing the stability of your alloy or carbon rig, keeping your wheel perfectly centered even when you are pulling maximum leverage on the bars and grips.
