Bottom Bracket Adapters: PF30 to Shimano/Sram
Convert a PF30 BB to Shimano Hollowtech II or Sram GXP.
Machined from alloy instead of flimsy plastics so they are more durable and less prone to deforming during installation and use.
They have multiple O-ring seals to help prevent the contamination of your bearings by water, grit, or grime.
This adapter comes with spacers and wavy washers.
