CYCLUS TOOLS T47 standard bottom bracket shell facing pair for 720151.
The new dimension in bottom bracket assembly, T47, combines the advantages of the BSA thread system and large-volume bottom bracket shells with a diameter of 46 mm, e.g. PressFit 30, BBRIGHT PressFit, 386EVO, OSBB.
Using this cutter, the existing bottom bracket housings can be milled with a flat surface, thus as with BSA, bottom bracket shells can be securely screwed into the frame.
The proper function of the milling cutter can only be guaranteed with metal. Furthermore, not every frame is suitable for this type of machining and conversion. Please ask the respective frame manufacturer!
