This bike part is a single-speed freewheel designed for bicycles, mountain bikes, and dirt jump bikes, with an 18-tooth freewheel layout for straightforward drivetrain use. Built as an HG-format freewheel, it is made to fit an HG-format freehub body and works as a practical replacement or upgrade for compatible setups. The machined metal freewheel combines an AL7075 wheel with an AL6061 spacer and cover for a solid, precision-made structure. At 69.3 g, this lightweight freewheel helps keep the rear hub assembly compact without adding unnecessary bulk. The toothed sprocket and cylindrical hub-mount section support fluid single-speed riding, making this machined metal freewheel suitable for everyday cycling and off-road use.
