Well, it is actually, but that doesn't mean your zombie steed shouldn't be able to roam the streets with you astride its back. Keep your vintage machine spinning smoothly with a Shimano UN-55 Square Taper Bottom Bracket and its sealed cartridge bearings.
Remember, never grease the axle flats of a square-taper bottom bracket, and resist the urge to put your Incredible Hulk strength into tightening the cranks down. Just go nice and snug!
