Miche Primato Bottom Bracket sucks

Haj
I have said this before, and Ill say it again, ITALIAN BB SHELLS ARE FINE, its the MECHANIC that causes the failure of the bb unit coming out. You need to tighten the bb in with GREASED threads, and torque down to 70 Newton Meters, with a torque wrench.

  And there will be no loosening.Put some responsibility on yourself, not the component giant Shimano. This could have happened with a Campagnolo BB!
                 Pardon me, but I once got stressed out by a dork who kept pestering me about "will by bb come out?"  I could'nt provide enough confidence with my work that day at the bike shop. Please confide in me though, when I say, Proper INSTALLATION and TORQUE spec ensures that an ITALIAN bb will STAY in PLACE
