This set is for pressing 24mm bottom brackets into a BB86 or BB92 frame. To install a conversion bottom bracket like the BB86-30, you will need a mixed set of drifts, which is available in the dropdown menu.

Our drift sets are designed in such a way that it is close to impossible to damage the bearing races during installation. Every set consists of two frame drifts and a frame guide. The guide centers the tool in the frame so everything stays lined up straight.

Born out of a frustration with the current offers on the market, we decided to tighten up the tolerances and design a set around the Park Tool HHP-2 bearing press, the most common tool used by professional mechanics.
