Water in seat tube?
Everytime I get caught in the rain with my Bianchi I end up having like an inch of water in my seattube, I can't see how it gets in there. Any suggestions on how to keep it from getting water? Thanksfully I have framesaver in there so hopefully I won't have any issues but it is getting annoying having to empty it out everytime and is getting a little worrisome.

Not sure about the source of the water, but a quick fix might be drilling a small hole in the direct bottom of the BB, allowing the water to drain. I'd coat the inside of the BB shell with grease though to be sure that the bare metal has as much water sealant/repellant properties as can be.

This is normal. The water usually gets in through the seatpost clamp area. If you have a bottom mounted cable guide just take out the mounting screw after a rain ride to drain the water.

I was amazed at the crude that got in the BB shell when I developed a click and removed the BB...
I have no idea how so much stuff gets in...
Take out the seatpost and hang the bicycle upside down...
Or drill a 'small' hole in the BB 'shell', not through the BB

To the OP, check with your LBS. Many bikes can be retrofited with a drain hole at the bottom bracket. My LBS did this for free on my Trek 5200. Otherwise, you'll need to turn the bike upsdie down as HT mentioned.

I suppose just turning it upside down as I've been doing is the easiest then. Unusually the bottom of the seat tube where it meets the bottom bracket is actually welded shut so there is no hole leading into the BB.

It's more of a concern if you've got a steel-framed bike, like my Sarthe. I put a bead of grease around the top edge of the seat post clamp, that seemed to make a difference. I think some black electrical tape would help prevent water from getting in there too.
Otherwise pull the saddle and hang the bike from a hook.
