Chiaravalli 428 Aluminium Blank Rear Sprockets

It's not always easy finding the right sprocket for your bike. Most of the time, sprockets are ready made and available in the size you need, but if your bike is old, rare, customised, or you're just trying to do something a little outside of the box, a blank sprocket might be the best option.

Chiaravalli aluminium blank sprockets are made from 7075T6 aluminium. They come with a raw aluminium finish, ready to be custom machined to suit your bike, or other application.

428 sprockets are ½” pitch x 5/16” wide.

We can offer a basic cutting service with a central mounting hole and bolt holes on most sprocket sizes. Contact us for details to see if this is something we can do for you.
