ressurecting this a bit,
have purchased from another source the CR1 SL, its got a bb86 ?
what do i need in there for my hollowtechII ultegra cranks?
There seems to be 4 or 5 different bb’s!
bb92-41b 86.5 x 41mm
bb91-41b 86.5 x 41mm
bb91-41a 86 x 41
bb91-41b 86.5 x 41
bb71-41b 86.5 x 41
then there are these
SM-FC7800p which are classed as “adaptors” for push fit hollowtech2
my brain hurts!!!!!!!!!!!!!!!!!!!
if youve had to do yours, any help would be great
