The Crupi "Solo" BMX Race Chain Tensioners keep a rear wheel with a 10mm axle in place in classic open dropouts, so it does not slip forward when you push out of the gate and the chain stays on.
They are CNC machined from 6061-T6 aluminum. Each tensioner has two axle holes with inserts, tension is set with a single screw and lock nut, and marks help to set both sides the same. Sold as a pair.
