usa BB

(1/1)

priv:
The metal cups on an unsealed usa BB is it a case of hitting the cups out of the frame or do they stay in?

and if you remove the cups when installing a new sealed BB do they have a lip on to stop them going too far into the frame?

basically i'm after advice on removing and fitting usa BB"s

the only BB's i've removed were on a MTB euro ones and they screwed in.

cheers.priv

theRuler:
hit them out

the lip stops em going in too far

you can fanny around with clamps n shite but a block of wood and a hammer is fine for hitting in unsealed bearing cups

RATTY:
Bang the cups out mate, they are tight but push fit. The new cups will go straight in the hole, may need some help with a rubber faced hammer if they are tight :daumenhoch:

priv:
thanks for the quick response men, i better get looking in the forsale/wanted now for a cheap light bb/and cranks.
