The Promax "C-1" BMX Race Chain Tensioners are chain tensioners for 10mm axles and classic open dropouts. They keep the rear wheel in place when you sprint out of the gate, so the chain stays on. Tension is set with a single screw and lock nut, the marks help to set both sides the same. Two axle holes, CNC machined from 6061-T6 aluminum, sold as a pair.
