Special tool HG 20

The HG 20 bicycle tool is a specialised removal tool designed for loosening and installing compatible Shimano HG 20-type threaded freewheels.

Key Features

Construction and Design

The tool is made from durable metal capable of withstanding the torque generated during bicycle repairs. Its accurately shaped splines engage with the freewheel fitting and provide stable transfer of force.

Main Functions

The tool is used to remove or install the freewheel on the rear wheel. Correct engagement helps reduce the risk of slipping and damaging the splines of the component.

Use and Compatibility

The tool is intended for freewheels using a Shimano HG 20-type fitting. Before use, its profile should be compared with the splines of the component, as cassette lockrings and threaded freewheels may require different removal tools.

Additional Features

Depending on its outer shape, the tool is operated with a suitable spanner, ratchet or socket. The rear axle nut or quick-release skewer may need to be removed to allow the tool to engage fully with the freewheel.

Summary

The HG 20 tool is intended for cyclists and mechanics carrying out replacement or maintenance of a compatible rear freewheel. Its durable construction and precise engagement profile support safe and controlled removal or installation.
