Should any grease or some other thread prep be used when using alu Campag cups in a ti bottom bracket? As the BB is an Italian thread I also need to prevent the drive side cup from unscrewing.

    Don't worry just use some copper slip, I use that on all my BB's and never had one under or seize.

    I have an italian BB and never had problems with loose cups... UT has hardly any drag, so I don't see why the cups should come loose. Copper paste and happy days

    I have a titanium Colnago fitted with Ultratorque cranks - the cups come pre-prepped with suitable thread locking compound - simply torque them to the required spec and away you go. If installing new ones, use a medium grade Loctite like 248 - it's an anti-seize too. The cups are anodised so shouldn't create any problems due to corrosion .

    Titanium is horrible stuff to work with, you certainly need something on the threads to reduce the risk of it binding

    I installed new Italian cups on my steel Pegoretti and the drive side cup did unscrew. I had to put Loctite on it. Is Copperslip a kind of grease?

    Coppaslip is an anti-seize. However, for Italian threaded BBs because of the inclination of the drive side cup to to unscrew, medium-grade Loctite is a better solution IMO - particularly as the Loctite acts as an anti-seize anyway.
