I've just got my first ti-axled BB. Frame is steel, BB threads are alloy, axle is ti, cranks are alloy.
The question is, what do I use on the tapers and the threads? With steel axles, I usually use threadlock on the tapers and anti-seize on the BB shell threads.
Anyone got experience? I gather ti and alu like each other a bit too much in a chemical bonding kind of way...

Thanks
Matt

I'd go with anti-sieze on cup threads, grease on bearing/axle contact surfaces and a lower-strength threadlock (eg Loctite 238) on crank bolts and tapers.

Copper grease on everything always works.
Except inside cassette bodies!

Finish Line Anti Seize Grease is like very thick copper grease. It seems to stay in place much easier. On my singlespeed the BB was always working loose using normal grease, not since using the thicker stuff, it almost sticks it in place.

Thanks people! Will go with anti seize on threads and loctite on the tapers and crank bolts (cartridge bearings, so no grease needed!)
