It is the tool to use when the classic Hollowtech II tool does not fit: on Dura-Ace BB9000 and BB-R9100 and on XTR BB93, the cups have a smaller diameter and need a dedicated profile. It replaces the Shimano TL-FC38 tool.\u003c\/p\u003e\n\u003cp\u003eIt is CNC-machined from solid aluminium in-house by Park Tool and anodized for instant identification. The 16 notches have a major diameter of 39-40 mm and a minor diameter of 37.6 mm. The 3\/8\" square drive works with ratchets and torque wrenches, while the integrated threads accept the BBT-RS retaining system, sold separately, which uses an adjustable spring to keep the tool fully engaged and prevent it from slipping off the notches during removal.\u003c\/p\u003e\n\u003ch2\u003eWhere to use the 39 mm Shimano bottom bracket tool\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eShimano Dura-Ace BB9000 and BB-R9100 bottom brackets\u003c\/li\u003e\n\u003cli\u003eShimano XTR BB93 bottom brackets\u003c\/li\u003e\n\u003cli\u003eToken bottom brackets with compatible 16-notch cups\u003c\/li\u003e\n\u003cli\u003eShimano STEPS E6000, E6002 and E6050 chainring lockrings on square-spindle e-bikes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose Park Tool BBT-49.3\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e16-notch 39 mm profile specific to compact Dura-Ace and XTR cups\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminium, light and precise\u003c\/li\u003e\n\u003cli\u003e3\/8\" drive to tighten with a torque wrench to Shimano's specified torque\u003c\/li\u003e\n\u003cli\u003eIntegrated threads for the BBT-RS retaining system\u003c\/li\u003e\n\u003cli\u003eAlso useful in the e-bike workshop for Shimano STEPS chainring lockrings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe tool is not designed for impact drivers or other power tools.
