Park Tool BBT-179 12-Notch 46mm Bottom Bracket Tool in Black

Brand:Park Tool

Code:QKBBT179

Park Tool BBT-179 heavy duty workshop bottom bracket tool.

Constructed from precision-machined 4140 steel, the BBT-179 is a heavy duty tool for the removal and installation of select threaded bottom brackets with 12-notch tool fittings. It is designed to be compatible with any bottom bracket with the corresponding tool fitting, with an extra-deep body to accommodate extra-wide spindles and low-profile walls at the point of engagement for recessed lockrings. The tool has three methods of engagement—a 0.95cm (3/8") drive fitting, a 2.54cm (1") hex fitting, and 36 mm wrench flats—allowing you to take on even the most seized bottom bracket cups. For added stability, the BBT-179 features integrated threads for use with the Park Tool BBT-RS Bottom Bracket Tool Retaining System or GPS-1 Guide Pins (each sold separately).

Features:

  • Fits 12-notch threaded bottom bracket tool fittings with a major diameter of 45–47 mm and a minor diameter of 44 mm.
  • Compatible with SRAM BSA DUB, Race Face Cinch, Rotor BSA30, Zipp Vuma, Hawk Racing BB3086, and more.
  • 0.95cm (3/8") drive fitting.
  • 2.54cm (1") and 36 mm wrench flats.
  • 5.00cm (1.97") outer diameter at point of engagement.

  • Not rated for use with impact drivers.
