The RISK RL235 Headset & Bottom Bracket Press Tool is designed for installing bicycle headset cups and compatible press-fit bottom brackets. It can be used for common semi-integrated headsets, external headset cups, and BB86/BB92 press-fit bottom bracket systems.

The tool uses a stainless steel threaded rod, aluminum alloy stepped press blocks, stainless steel nuts, and a flat thrust ball bearing system to help apply smooth and even pressure during installation. The multi-step press block design allows the upper and lower headset cups to be pressed at the same time, improving installation efficiency.

It is suitable for home mechanics, bike repair shops, and workshop maintenance for MTB, road, gravel, and other bicycles with compatible headset or press-fit BB standards.
