Sprocket rear blank , Universal #520

Sprocket, Rear , Blank #520, Aluminium, (Gold)

These blank #520 sprockets are designed with the custom builder/racer in mind.

Finding the correct sprockets for your special is never easy, so we’ve done the hard work for you. All that’s left to do is turn out the center and drill the mounting holes.

Designed and machined in house from super strong 7075 T6 aluminium, and then anodized in gold colour for superior corrosion and abrasion resistance.

We advise seeking the advice of an experienced machine shop for truing up the sprocket prior to machining the center bore and mounting holes to ensure perfect concentricity and bolt fitting.
