This press-in bottom bracket is designed for use on
frames with a BB shell inside diameter of 41mm and a width of 86mm. Because manufacturing tolerances vary, on many frames,
no special tools will be necessary to install the cups as they will press in by hand. On frames with a
tighter fit, a mechanical means of pressing in the cups may be required.This can either be a dedicated
tool for BB86/BB92 applications, or you may improvise with a threaded rod, nuts, and fender washers. A center seal where the two-halves meet provides sealing from the inside of the frame.
chromium steel bearings use ABEC 5 cartridges with precision Grade 10 balls. The angular
contact design ensures 100 percent ball engagement for greater strength and longer life.
These Bottom Brackets do not use axle
us to reduce the bearing ID and use
balls for greater strength!
