WORKSHOP DUMMY HUB PARK TOOL DH-1

The Park Tool DH-1 workshop dummy hub slides into the rear dropouts in place of the wheel and keeps the chain in place while the wheel is off. It is not a hub for building wheels: it is a workshop tool that makes cleaning, servicing, transporting and storing the bike easier.

With the DH-1 installed you can pedal and shift gears even without the rear wheel. The chain stays where it belongs instead of dropping onto the frame, and the drivetrain can spin freely: ideal for a thorough chain clean or for tracking down a drivetrain problem. It fits both quick-release frames and 12 mm thru-axle frames.

When you need the DH-1 workshop dummy hub

• Chain cleaning: the drivetrain turns and you can work on chain and sprockets without the wheel in the way.
• Drivetrain diagnosis: pedalling and shifting with the wheel removed makes it easier to find where a problem starts.
• Transport: with the rear wheel removed, the chain stays in position.
• Storage: the bike can be stored without its wheel while keeping the chain tidy.

Why choose Park Tool DH-1

• Compatible with all multi-speed chains and 1/8" chains.
• Fits quick-release and 12 mm thru-axle frames.
• Lets you pedal and shift without the rear wheel.

For anyone who washes the bike often or transports it with the wheel off, the Park Tool DH-1 workshop dummy hub is a small tool that saves time and keeps chain and drivetrain in order.
