DH-1 Dummy Hub

The Park Tool DH - 1 Dummy Hub is an essential accessory for your bike. It easily slides into the rear dropouts of your bicycle frame, replacing the rear wheel. This keeps the chain in place when you remove the wheel for cleaning, servicing, or transportation. With its unique design, you can pedal the bike and shift the derailleur, making it perfect for chain cleaning and diagnosing drivetrain issues. It's compatible with all multi - speed and 1/8' chains, as well as quick - release and 12 mm thru axle frames. A must - have chain keeper for every cyclist!

Using the Park Tool DH - 1 Dummy Hub is easy. First, remove the rear wheel from your bike. Then, slide the DH - 1 into the rear dropouts of the frame. Make sure it fits snugly. With the hub in place, you can pedal the bike and shift the derailleur, which helps you clean the chain or check the drivetrain. When you're done, simply remove the DH - 1 and put the rear wheel back on. As for maintenance, keep it clean and dry. You can wipe it with a clean cloth after each use. Store it in a cool, dry place to prevent rust. And always check for any signs of wear or damage before using it again.
