how much??

They must be pretty cheap coz its just plastic

it doesnt say on there website either it just says they will be cheaper than the normal won

i wouldve expected them to be alot weaker than normal BBs so yea cheaper but if theyre stronger and lighter then alot more expensive

yer probly

i would run these if i needed a new BB without a doubt.
Oh and by the way, bushings should hold up in a BB easily, they use them in various high end hubs [proper magnalite] and most sealed pedals.
