Prevent the headache and frustration of removing your hub's end caps or dust shields during routine maintenance or swapping over to a new standard with the Hub Genie from Unior. This simple, yet unique tool uses an expanding mechanism, grabbing the hub end cap evenly from the inside. With a simple yank, it easily removes even the stubbornest end caps, and unlike the traditional method of removing end caps by pinching and pulling with pliers, this tool won t damage or mar the caps or hubs.The tool is available in two sizes, a smaller one for 12 and 15mm thru axles and bigger version that works with 20mm thru axle hubs. Both versions feature plastic-dipped handle for better ergonomics and grip.
