PARK TOOL OVERSIZED HEADSET CUP REMOVER RT-2

The Park Tool RT-2 oversized cup remover is built for large-diameter head tubes: 1 1/4" and 1 1/2" cups, as found on tapered-steerer MTB, gravel and e-bike forks. It covers SHIS ZS44, ZS49, ZS55, ZS56, EC49 and EC56 and works on cups and bearings with a 38 to 55 mm inside diameter.

Lower 1 1/2" cups are often the most stubborn to remove, with a wide contact area and years spent pressed in place. The RT-2 goes in from the top, the flared fingers open behind the cup lip and every mallet blow pushes evenly around the full perimeter. The tool also handles bottom bracket cups on one-piece crank systems. Before striking, check that both fingers have caught the lip: a partial hold would put all the force on one side.

Why choose Park Tool RT-2

• Fingers sized for oversized bores, where a standard remover has nothing to bite on.
• Even force across the whole cup, so it comes out square without marking the head tube.
• 25.4 mm shaft in heat-treated alloy steel with a nickel finish.
• Complements the RT-1: together they cover cups from 27 to 55 mm inside diameter.

If you work on modern frames with tapered steerers, the Park Tool RT-2 oversized headset cup remover takes out even the largest lower cups without putting the frame at risk.
