Italian bottom brackets - how bad are they?
« on: July 27, 2020, 05:39:17 pm »
I've bought an old Eddy Merckx frame and, despite being Belgian, they all have Italian BB shells.  Do you simply install the RH cup bastard tight and/or use threadlock?  It'll be a conventional Shimano 7400 or 6400 BB.  I have a big fixed cup spanner.

Italian driveside BB cups are fine if the frame is faced, the cup done up bastard tight and weak threadlock is used. Miss one of the three and it will probably stay in place. Miss two and it won’t.

Ugo De Rosa helped Merckx set up his factory and I guess Italian BBs stuck around. https://www.marchettispa.com/ were the biggest manufacturer of production framebuilding equipment but might not be now.
