Drill a hole to allow water drainage

angotja said:

6/ 04 issue of MB Action "Ask R.C." section there is a
question about
drilling a 1/8" hole in the bottom of the bottom bracket
to allow
water which has entered the frame to drain and prevent
corrosion.

R.C. says this is a wise mod. Anyone else out there doing
this? If so, would you recommend that others perform
this mod?

If I recall correctly, that was specific to a certain make
and model of bike and not all of them.

Do you ride through a lot of water, or in the rain? If not
think of it as a way in for dust rather than a way out for
water. Almost certainly voids your warranty. I did it on a
couple bikes, more to let the BB dry than prevent corrosion.
It worked.

Even better (if moisture is an issue) is to install a BB Dry
Valve from Action Tec. It's a one-way valve, allowing water
out but nothing in.

My Cross-Check came with a hole in the bottom of the BB
shell - damn I love Surly. If you're comfortable running a
drill bit through your frame, fire it up.

Mine already has a hole.

Upon further consideration, I have decided not to drill the hole. I reckon that if I experience any water damage, and there is no drainage hole, the damage will be repaired under warranty by my mfr. Thanx for input.

I doubt it, sounds like a maintenance issue.

Er, no it won't. That would just fall under wear and tear /
maintenance / abuse.

A hole in the BB shell might be a good idea if you routinely
have water settling there. Major causes are a rear-facing
seat tube clamp or an open-topped seat post.

The main caveat with this issue is that a hole in the BB
will also let in water as well as let it drain out. This
means that your BB will need regular servicing and is likely
to see quicker wear than normal.

I'm thinking that because it's steel it's less of an issue
than it would be with aluminum. Almost all steel bikes have
a hole at the bottom. Most road bikes and older mtbs screw a
plastic cable routing clip into the bb. /scott

And my old Giant. Never have had a BB problem.

Yikes...structural integrity?

Yikes...if it didn't come with a hole there's a reason.

Yikes...not drilling any fscking hole in my BB!

BB's are more easily replaced than a whole frame.

Peace, Bill The mind serves properly as a window glass
rather than as a reflector, that is, the mind should give an
immediate view instead of an interpretation of the world.

IIRC the problem was that the seal on that specific BB was
suspect... I don't believe that they recommended it for
every bike.

Sounds like they're talking about the frame, just under the
bottom bracket. My chro-mo Marin already has a hole there.
Is it even an issue for anything but steel?

my alum. K2 has it as well, there's a twist.

I recently cleaned and lubed my bike. When I turned it upside down, and let it sit, water started draining from the seat post and from the stem. This is a cause of concern for me...

I noticed 2 holes on the frame just ahead of the bottom bracket with screws holding nothing in them. I wonder if these are intended for drainage?

They're either water bottle bosses or, more likely from your
description, mounting screws for an anti-chainsuck device.
Don't sound like drainage holes, but take out screws
(bolts?) and see.

You should try to figure out where water is getting in the
frame, and correct it. (I have a gift for the obvious.)
Might be as simple as greasing the seat post, so moisture
doesn't slip in there.

Tough to do if it's transferring by condensation in the
tubes. You take your bike from your nice warm house out
into the cold and what happens? Or is it the other way
around? I forget!
