Bicycle hub axle for REAR BMX hubs. These are some "unknown" axles I received in a large parts lot a few years ago.
Color: GOLD (YELLOW ZINC finish)
Dimensions: 150mm overall length (each threaded section is 56mm, center unthreaded part is 35mm)
Threading: 3/8" x 24T (usually coaster brake). Skyway mags are also sometimes 24T in the rear even when freewheel.
Weight: 69g (which is the same weight as the solid chromoly ones we sell, so they are probably also chromoly)
