Review on 🚲 CDHPOWER 56 Teeth Sprocket for 410/415 Chain - Multifunctional 2 Stroke Gas Engine Motor Gas Motorized Bicycle by Marcus Amillion

So this would get five stars if it just MENTIONED that the 6 hole internal pattern CANNOT be used with ANY traditional bike design. To use a 6-bolt hub to mount the sprocket, you must cut a 2.5" diameter center hole in the sprocket to mount a separate disc/sprocket adapter. This adapter costs about $29 with Prime. So if you were planning on using this sprocket directly on the disc hub, forget it. You have to use a hub mount or a rag mount (broken spokes in the sand). Hole in the sprocket in a variety of ways, most commonly using a 2-1/4" Lenox hole saw and mandrel (about $25). Or you can attach this to your new band saw or plasma cutter.
