The torque spec for bottom brackets is usually around 30 to 35 ft/lbs. That's a pretty good amount. It's more than I would have used if left to my own judgement. Judging from the majority of bikes that I've worked on, it's more than most other mechanics use when left to their own judgement too. Bottom brackets are one of three places on a bicycle where I use a torque wrench.
