Bottom Bracket – White Industries, square taper, stainless steel

The $20 Shimano cartridge BBs work great, if you want to go fancy and don’t want to commit to the once-a-year maintenance of the IRD cup-n-coner, get this White Industries one instead. They’re made in Petaluma and should be good for a long, long time.  

White Industries square taper stainless steel bottom brackets

JIS taper for White Industries, Shimano, Sugino, Clipper, etc. (but not Campy) cranks.

All our bikes have 68mm bb shell width except the Gus and Susie which have 73mm bb shell width.
