Re: bottom brackets:

Mine is squeaking something horriffic, which is driving me nuts because it's *new*.

I expect it's a cartridge. any ideas? I've ridden it in rain but that shouldn't really affect it... =P

If it's new and your LBS installed it, take it back to them and get it checked for free. It shouldn't squeak. Does it squeak when you turn the crank by hand? I'd pull off the crank arms and check the bb independent of the crank. When you put the arms back on, make sure they are installed VERY firmly. Is there movement between the bb and the frame shell (this is easier to test with crank arms on)? You could drip some oil into the spindle/bb interface if that is the origin of the squeak, but a squeak there is probably indicative of faulty tolerances in manufacturing.
