Freewheel thread extender

A helpful add-on if you're riding the Phatmoto Rover. It attaches to the Gemini hubs freewheel threads, then your freewheel sprocket spins on to it. Helps you achieve pedal side chain alignment by moving the freewheel threads a half inch towards pedal side. A must have if ordering a wheel set for the Rover.
