Shimano Nexus INTER 3 Speed Sprocket Adapter 3/8ths Bolts
Made in China. Will accept Manic Mechanic Sprockets, USA Made Thick sprockets, and Chinese made CNC Sprockets.
These 2-piece, balanced adapters clamp solidly, and perfectly centered to coaster brake hubs. That means that instead of driving your rear wheel by way of the spokes, you actually drive the wheel through the hub. These are super quick & easy to set up, and you can easily align the chain with the engine’s sprocket. Especially helpful if you have fat tires or your engine is offset.
