Park Tool Dummy Hub The Park Tool Dummy Hub fits into the rear dropout and will hold the chain in place when there is no wheel present, such as when the frame is packed up in a box or bag for transportation. Fits both quick-release frames and 12mm Thru-axle frames for road or mountain bikes. Will work with Shimano, SRAM and Campagnolo.
