This tool is designed to remove the non-threaded bottom bracket bearings and cups of the BB90 bottom bracket system. It also supports other press fit standards with 24mm spindle, such as BB86, BB92, SRAM Press Fit GXP. The removal tool will pull the bearings & cup from the frame. Carefully insert the guide head of removal tool trough the bottom bracket cup (marked green).
To remove the bearing cup from the bike frame, screw the nut as long as the puller does not completely extracts the cup from the frame. Repeat steps on opposite side.
Assemble bottom bracket cups and our bearing cup press tool (item 1680/4) as shown. Turn handles of the bearing cup press, making sure the cups are always aligned. Continue pressing until each cup is completely pressed into the frame.
