Park Tool DH-1 Dummy Hub Chain Keeper

Support the chain while the rear wheel is off

The Park Tool DH-1 fits in the rear dropouts after wheel removal, taking the wheel's place as a chain guide during cleaning or transport. It keeps your maintenance setup more manageable without reinstalling the wheel.

• Supports the chain with the rear wheel removed.
• Useful for drivetrain cleaning and bicycle transport.
• Design allows the drivetrain to be shifted during maintenance.
• Works with derailleur chains and 1/8-inch chains.
• Compatible with open-dropout frames and through-axle frames up to 12 mm.

Before ordering

Check your frame and axle arrangement. Follow the manufacturer's fitting instructions and remove the tool before reinstalling the wheel and riding.
