Replacement Dustcaps F1 Ceramic BBs


Product Description

To keep your BB running smoothly year after year, we offer replacement dustcaps for our F1 Ceramic BBs.

Over the years we've had a few different designs, explained below.

  • Our current design uses a silver inner race (on both BB bearings) and a plastic outer dust cover. If your BB uses this, please choose the "SHIMANO or SRAM GXP (new style)". This style works with ALL Shimano or SRAM BBs that use the silver inner race. Please note, we do not send a new silver race as those typically do not need to be changed. We only send the 2 outer dust covers.
  • Users of our older Shimano BBs, with all black plastic dustcaps that snap into the bearings should choose "SHIMANO (old style)".
  • Users of our older SRAM BBs, with all black plastic dustcaps that snap into the bearings and a shim on the non drive side (NON DRIVE is printed on the black shim) should choose "SRAM GXP (old style)". This kit includes new shims and wave spacer.

Please view the pictures below for help in determining which type of dustcap you need.

We recommend also buying our F1 Turbo Grease or Rocket Sauce to apply before installing dustcap/dustcover to help protect the bearings from the elements.
