The purpose of the tool is to press out the threadless bottom brackets BB30 and Sram DUB from the frame. The tool safely presses the caps of the bottom bracket out of the frame without the need for hammering. It features two interchangeable pressure plates: a 30 mm plate for the BB30 standard and a 29 mm plate for Sram DUB press-fit bearings. The 30 mm plate also makes it suitable for many other bearing standards with a 30 mm inner diameter. The rubber O-ring ensures a more secure fit of the tool, preventing scratches on the frame.
