Hi,
I've got a 2011 Specialized Sirrus Elite with an annoying creak from the BB. I have tightened pedals and crank bolts without getting rid of it. I've ordered a crank puller tool online with the intention of tightening the BB but have just seen that the price of a new BB is very low so now plan on replacing the BB whilst I'm doing the job.
The trouble is I don't know the length of BB spindle that I need. I know that the spec is a 68mm square taper BB but have seen that these come in various lengths.
Anybody have the definitive answer?
Cheers,
Stu

It looks as though this is the crankset and bb on your bike.
