The Enduro BRT-040 Series of tool kits for bottom bracket bearing removal and installation is designed for use with BRT-060 and BRT-050 bearing presses (sold separately). (Note: part # BRT-040 also works with hub bearings). This kit expands upon the functionality of the BRT-060 and BRT-050 bearing presses to allow for the gentle removal and installation of BB bearings by utilizing the nut and threaded rod from the bearing press to press the bearing from the component. This is ideal for bearings like stainless steel and XD15 that can be removed and cleaned over and over again should they become rough and gritty with dirt. These kits includes cups guides and pullers to allow for the removal and installation of BB bearings when used in conjunction with the BRT-060 or BRT-050 bearing presses.
