• Changing sprockets on threaded hubs can be a time consuming operation. The 1722/2BI is a unique tool for removal of different standard sprockets from a threaded hub.

How to use the tool:

• With Unior’s 1722/2BI you can firmly grab the complete sprocket from two sides, turn the spindle and fix firmly. The spindle and the side bushings on the tool create a strong grip. By turning the tool counter clockwise you can unscrew the sprocket.
