HSC PF30 Ceramic Adapter Bottom Bracket

Article number: 010-04-07
Availability: In stock (3)

The SRAM-developed PF30 bottom bracket shell standard was originally designed around the modern BB30 crankset standard. Fortunately, the enlarged shell with its narrow bearing stance allows this standard to be adapted to fit older 24 mm crankset spindles. HSC manufactures these PF30 compatible bottom brackets to fit both Shimano's Hollowtech II and SRAM's GXP cranksets. These bottom brackets use the same size 6805 bearings used in the manufacturers' stock bottom brackets, but offer a performance uprade with an ultra high quality hybrid ceramic configuration.



These adapters are designed to fit frames with 46 mm diameter and 61 mm(OSBB), 68 mm, 73 mm, 83 mm, or 100 mm wide bottom bracket shells. The option you require will depend on the crankset being used:

  • Shimano HTII - Adapts to fit 24 mm spindle cranks
  • SRAM GXP - Adapts to fit stepped 24 / 22 mm spindle cranks.
  • SRAM DUB - Adapts to fit SRAM's proprietary DUB design, 29 mm spindle crank.
  • BB386 EVO - Designed to fit 30 mm spindle cranksets, sometimes referred to as "long spindle" BB30 cranksets.
