I've just thrown away a worn out DA BB. Served me well for many years.
I'm considering replacing it with the Ultegra BB as its cheaper and may be better sealed. I can
accept the greater weight. But before I buy, I want to know what's inside, in terms of bearings and
sealing. With the DA BB its easy, as it can be disassembled, inspected and maintained. But,
Shimano's web page shows a two!!! piece exploded view of the Ultegra BB. Not very revealing... to
say the least.
Can anyone comment on...
a) What kind of bearings are inside the Ultegra BB (roller, ball, combination a la DA)?
b) Whether the sealing is actually better that the DA version?
c) Any other comment on stiffness / longevity / etc...
Thanks in advance.
