Shimano Tourney Rear Mech Derailleur - 6/7 Speed

Use a degreaser and brush to remove dirt and debris. Rinse with water and allow to dry. Apply chain lubricant.

You will need a hex key set, a screwdriver, and possibly a chain tool for chain adjustments.

It's compatible with 6/7 speed chains.

Lubricate the derailleur and chain every 100-200 miles, or more frequently in wet or muddy conditions.

While it can technically work, it's primarily designed for MTB use and may not offer the best performance for road bike applications.

Use the limit screws to prevent the chain from shifting beyond the largest or smallest cog. Turn the screws clockwise to limit movement and counterclockwise to allow more.

The SGS cage is a long cage design that allows the derailleur to handle a wide range of gear sizes, including up to 34-tooth sprockets.

Check and adjust the cable tension. Ensure the derailleur hanger is straight. Inspect the derailleur for damage.

Adjust the limit screws. Check for chain wear and replace if necessary. Make sure the derailleur is aligned with the cassette.

Lubricate the chain and derailleur. Check for bent derailleur parts. Ensure the chain is properly aligned with the cogs.
