Frame Ventilation

I have heard that a good steel frame has a lot openings so it can dry out and hopefully prevent moisture build up and rust.

I had an old Braxton which took it to the extreme.

I have also owned a couple of Thorn bikes and one even had sealed tubes. Does that make sense to you? Unless they somehow created a vacuum when sealing them, there will be no place for the moisture to go.

Wondering what your opinion is on this. When I lived in Seattle, a respected mechanic would routinely drill a small hole in the bottom of the BB to let moisture run out and I am thinking of doing this to my steel frame.

I have a similar set of slits on my BB, but it's a cromo CX frame and it actually has holes all around because welding or brazing = heat and expansion.
Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

use framesaver, first of all
and drill a small hole on the bottom of the bb shell.
cover with tape.
after it rains, turn bike over and peel back tape.

use frame saver or any spray oil type water displacer - I used a spray can of Gun oil that worked very well.
It seems a hole in the BB would allow more water in. If you are worried about water in the BB area just take out your seat post and turn your bike upside down.
