This BB is designed for 30mm spindle cranks installed into press fit style BB86 and BB92 bottom bracket shells that have an internal diameter of 41mm. They have a 30mm ID bearing to work with our MR30 series cranks as well as many other manufacturers that use 30mm spindles. Bearings are Enduro stainless steel angular contact and the kit includes (2x) 1mm spindle spacers.

Keep in mind when calculating for compatibility that “86” bottom bracket shells actually measure 86.5mm and “92” shells actually measure 92.5mm. For descriptions they are normally referred to as just “86” or “92” shells.

Specs
  • Enduro stainless steel angular contact bearings
  • Cup outside diameter: 41mm
  • Cup flange diameter: 44mm
  • Cup width/flange thickness: 1.5mm
  • Comes with 2pcs of 1mm x 30mm spindle spacers
  • White Industries R30 and G30 cranks will only fit on 86 shells
  • White Industries M30 cranks will fit on both 86 and 92 shells, with 86 shells requiring 2x 2.5mm spacers (1 on each side, not included)
Instructions

  • Always use a press to install cups/bearings
  • Light preload on bearings is all that’s needed!
  • Start with no spacers and see if that works, then add 1 spacer at a time (either side) to check bearing preload
  • Always back out bearing preload collar before torquing crank arms
  • Starting with too many spacers will permanently damage the bearings if arms are torqued down
