With a channel in each side, this tool can be mounted in a vise, to keep things sturdy while you work on your R4 or R6 hubs.

It also features a close-fit inside diameter to allow for XD and HG freehub servicing. Just pop your freehub body inside the support tool and you have the perfect setup for knocking those bearings out. Fits Sram XD and Shimano HG freehubs best. Shimano Microspline freehubs are a loose fit. 

Made from highly impact resistant UHMW polyethylene. Fits vise jaws up to one inch (25.4mm) tall.
