Headset and Bottom Bracket Cup Remover

The RT-1 makes press fit headset and bottom bracket bearing cup removal easy. The tool is pulled through the frame until the flared ends snap in behind the cup. The tool end is struck with a mallet and the flared ends evenly distribute force around the cup as the cup is driven out. Strong heat-treated alloy steel construction with nickel finish for a long service life.
