The Sealed USA 19mm Bottom Bracket includes two green-ring sealed bearings, a splined cylinder, washers, and circular spacers—all arranged on a white background.

Description

A sealed bearing bottom bracket for USA sized frames. It takes the place of a loose ball setup, so the bearings run in sealed cartridges instead of loose in the cups.

It suits 19mm spindles and USA bottom bracket housings with a 51mm inner diameter frame housing. Supplied in black.

Features
  • Sealed bearing upgrade. Swaps a loose ball bottom bracket over to sealed, which is the easy win when you are fitting fresh cranks.
  • Suits 19mm spindles. Made for 19mm spindles, so check what your cranks run before ordering.
  • USA housing fitment. Fits USA bottom bracket housings, meaning a 51mm inner diameter frame housing.
  • Not for loose ball spindles. The listing is clear that this suits non loose ball 19mm spindles, so it will not save an old loose ball crank.
  • Finished in black. Black only, so it sits quietly inside most frames.
