BB90/95 Trek OVERSIZED (Ø ext 37,1mm) Bottom bracket for Shimano 24mm - BK-5419

BB90/95 bottom bracket for Shimano 24mm cranckset 

High quality bearings "Enduro Bearings"

Include with seals, wave washers and spacers

Trek BB90 bottom brackets require the bearing to be directly pressed into the BB shell that is usually made from a material that is softer than steel (carbon or aluminum), and over time quite often the bearing seat can become slightly oversized from use. The custom replacement bearings in this kit have been made just slightly oversized (0.1mm) to compensate for any slop that may have developed in the BB shell.
