Park DH-1 Dummy HubThe Park DH-1 Dummy Hub is also called the “Sleeping Hub” because it sits in the frame’s rear dropout to act as a placeholder for the rear wheel while the chain is being cleaned or traveling. The innovative design allows the chain to shift gears with the Dummy Hub in place. Compatible with all derailleurs and 1/8’’ chains. Compatible with frames with open-type dropouts, as well as 12mm thru axle dropouts.763477002709
