Keeping water out of the frame
Well my Trek 5200 arrived and after assembling it, I realize how many entry points there are for water. The drill outs for the water bottle cages, the bracket that holds the handle bars. Holes where the cable comes out of the frame.
For a carbon frame does it matter?

i'd be serprised how much water gets into a frame realy, and as the BB is the lowist point it will all meet there, i normaly cover the BB in copper grease just to stop corrosion and ofcourse do the threads

But the BB shell is solid, right? That is, if you remove the seat, and pour a cup of water down the seat tube, none of it is gonna go into the BB shell. Right? Maybe it's different on a CF frame.

Wow, I was wondering about the same thing on my bike. There are holes everywhere that water could sneak into.

Since I ride in the rain a lot, I make it a point to occasionally pull the seatpost and tip the bike upside down to expunge the frame of any water from time to time.

Some wheelsets (Rolf Vector Pros) are notorious for collecting water during rain rides. PITA. The only real remedy for those is to pull the tire and rim strip to let them dry out.

i think this idea has come up on here before and ive heard of people doing this regularly with AL frames... Drill a small hole at the very most bottom part of the BB. that way any water in the frame will drain out.

Tonight, I'm going to put a simple gasket around those cage holes to block water. And look for other entry points. Water seems to be a problem in general. Last night while installing the rear blinky, I noticed that the bracket screw that goes directly to inside of the light was unsealed. The small gasket I made should work. The light did have a gasket for the permimeter tho.

My experience is that, during heavy rain water will find a way
in no matter what. So, the some other posters have said, it's
more a case of finding ways it can get out rather that going nuts
trying to stop it getting in.
Having said that, I dont have a carbon bike.
