Water in bottom bracket?

Guest
I recently replaced my Capy Centaur 53/39 with a compact. I had the funky
Centaur BB, and took it by the bike shop to have them break it loose. When
they did, water poured out on the floor. I looked underneath the BB and on
the chainstays, and there are no drain holes.

First, I avoid riding in the rain, but I occasionally get caught in it.
Next, it appears there are some decent size holes around the water bottle
mounts.

The bike has had about 2000 miles of opportunity to collect water, so how
did it get in? How should I get it out, and how should I keep it out?


PS - it's an all-aluminum frame, if you want to suggest drilling...

I would suggest drilling a small hole in the bb shell, and then plugging it
with a rubber plug or stopper, a good place to look for a plug would be an
auto parts store, Or even a home / harware store. It is definatley not good
to be storing water in your frame.

It probably got in between the seat post and seat tube. Put a good coating
of grease on the seat post, and put some caulking in the cutout of the seat
tube. The grease will also prevent the seat post from getting "frozen" in
the frame.

Why plug it? Gravity will do fine.

Probably down the seat post, though very small amounts also could have
come past the headset and through the downtube if the headset is not
sealed and the head tube is open to the other tubes, which is usually
the case. Given the lack of ventilation and/or escape routes, the
water may have collected a few drops at a time, and even condensation
from temperature changes might have contributed if you live in a damp
climate.

> How should I get it out, and how should I keep it out?


Assuming that your seatpost is not carbon, pull it out and thoroughly
grease the inside of the seat tube before reinserting the post; this
will help to seal the path against additional water intrusion. Then,
assuming that you've installed a sealed cartridge BB, drill a 1/8" or
larger hole in the bottom of the BB shell and just leave it open.
Many frames are supplied with such a hole present; it does not seem to
cause any problems. If you limit the amount of water coming in, and
allow that which intrudes to escape, the problem should be solved.

Drilling a hole at the bottom of the bottom bracket and greasing the seat
tube are both very good ideas.

Water can also accumulate via condensation; storing the bike in a cool
place, taking it to a warm environment and then returning to a cool place. A
hole in the bottom bracket and occasional removal of the seat for several
days when not using the bike will allow water to escape. Or you could keep
your bike in the house which may ******** the wife, but you won't have
condensation problems! <grin>

Well yeah for draining, but you wouldn't want road grime and dust / dirt
getting up in there.

That's no problem with a cartridge bottom bracket. Leave the hole open
so you can't forget to unplug it.

You could trade in your wife for a cycling compatible model.

What's the plug for?
A hole is sufficient.

Well I was thinking you might not want road grime / dust / dirt getting in
there, even with a sealed bb it might degrade the seals slightly quicker.

Drill the hole and leave it open.

Apparently that's a nonissue. Traditionally the artisan builders have cut a
rectangular window or taken the opportunity to do something interesting like
playing card suits or letters.

Apparently it has cooties. There's a lot of negative buzz about it that strikes
me as received lore and exaggeration.

Luckily, my wife is my riding partner so there are no problems there. She's
the kind that dogs me, pretty much regularly, about getting out and going
for a ride. I hate it when that happens!

It's a well designed piece recombining existing proven
Campagnolo bits. Perhaps someone's uninspired by the color
or some other small aesthetic point ?

The holes you see on some bikes, on the stays, are not drain holes,
either. They are there to let heated air out during welding/brazing,
which would othewise ruin the weld/brazing.

The water is most likely getting in around the seatpost collar. A lot of
water splashes up there in the rain. Grease the seatpost well before you
re-insert it.

Drilling a hole in the bottom of the bottom bracket always strikes me like
Curly Joe drilling a hole in the bottom of a boat to let the water out.

Uh, no. There is about 2 liters of air inside the tubes of a bike. How
much water do you think is in that air? It is a very, very small amount.
The air also circulates very poorly, so you don't exchange much warm air
for cold air in the process you describe. There is essentially no water
getting in that way.

Water may condense on the outside of the bike if it is cooler than the
air, but in that process a large volume of air circulates past the cold
metal, giving up water as it passes.

Sorry - I've been out of town for a while. It was the one with the teeth
on the outside, which requires a special tool, that doesn't fit any modern
Campy BB's.
