Water in the frame?

[Zula]

Thanks for all the advice.

 

Off to the garage

[stewie911]

Do what I do when out on the road without the torque wrench. (Real simple actually)

 

Just count the revolutions as you loosen the bolt and remember the angle of the allen key. The water will eat away at your bb.

[The Drongo]

using a torque wrench to tighten a seatpost bolt is like using a 747 to tow a glider. Total overkill.

 

Just remove it, and re-tighten when all the water has been released from the frame. It's not rocket science. Plus, you'll need to know how to do it if you need to adjust the height on the fly. Are you going to take your torque wrench with you on each ride?

 

I thought not.

 

NUBBIN. Its a torge wrench, not a monkey wrench !!!

[Johan Bornman]

Just drill the damn thing.

 

Water inside a frame is evil. In carbon frames it causes a galvanic action with alu BB inserts and eats the alu. I have posted photos of this effect on a Cervelo on this forum.

 

Water inside the BB rots the BB bearings from the inside out. There is nothing wrong with drilling a small hole (6mm or so) in the BB shell. It will NOT affect the structural integrity of the bike at all.

 

Further, as from April, frame suppliers will not be able to discriminate you in case of a gaurantee claim. If the hole is not related to the frame defect, they cannot void the gaurantee.

 

Drill away and save yourself money.

[The Drongo]

And? ther you have it!

 

Can we go sleep now while you disturb your neighbours with your drilling and banging?

 

Lekka!

Just unscrew the little bolt at the bottom that the cable guide is fixed on with. It should all drain out. Otherwise doesn't your bike have holes in the rear of the chain stay right at the rear axle. It should drain out there if you put the bike on it s back wheel.

Hmmmm....only crappy mt bikes have cable guides at the bottom of the BB.

 

If you open enough BBs you'll soon realise that a cup of water in there almost never drains out the weld vent holes in chainstays or seatstays.

 

BB drainage is a must.

oi! My MTB has cable guides at the bottom of the BB! Granted, I have converted the cables to be fully enclosed throughout, so it's now useless, but anyway...

Johan!!! I am shocked at this advice.

 

Take the seatpost out and refit. Find a torque wrench from a friend, but for goodness sakes don't drill into your frame.

You are kidding me, aren't you? Do you really think a refitted seatpost tightened with a torque wrench will seal the drip? Further, what problems do you foresee with a hole in the BB?

[HeartCoppi]

Thanks JB, your advise is a preventative maintenance measure and sound.

 

Just taking out a seat post continuously is purely a reactive maintenance measure and does not allow ventilation to address low moisture contents.

[LazyTrailRider]

People scared of loosening seatpost bolts?! Honestly, what has this world come to?

 

I agree, drill it. It's not like you're machining a freakin' laser mounting bracket onto your bike... It's a small hole, sheesh.

 

Reminds me of when we moved into our new offices and I asked one of the developers (he called himself that, at least) to fit a normal plug to a multi-plug so he could get going and not have to wait for the technical guy. His response: "But I'm not an electrician!" Needless to say, he doesn't work for us anymore. I sometimes wonder why the rest of keep on turning the world for people like him.

I take it that you have a carbon frame (based on the fear factor)

If you do not have holes in the down tube for bottle cage bolts that you can undo, then fear not and try this.

 

If you do not have a torgue wrench, this is the general rule of THUMB for tightening to the correct(ish) torque.

If your clamp bolt is 5 or 6mm allen, take an extended lever allen key, support it in the four fingers of your GOOD hand, with your thumb placed like this just below the end of the long leg. Place the short leg into the bolt and tighten using the pressure of your thumb only, until you can push no more. If you check with a torque later, the difference will be minimal.

 

Ali and steel welded frames should have small holes present at the rear dropouts (at least), for release during welding and powdercoating. Standing the bike front wheel up sometimes allows drainage, as there are holes inside tubes at all joints that will allow the water to get through to this point.

 

If you are going to be drastic and drill holes, perticularly in the BB shell, don't forget to ensure that you: 1 - remove the BB and its water seal tube before you do. 2- always ensure that same is installed when new BB cups are installed.

 

Hope that helps.

 

DRILL CARBON FRAME - eiiish!

 

 

Water in any frame not good. Why scared of removing seatpost, it is not made of class. Drill hole in frame. I have done that with my SCOTT carbon CR1, no problem. I have'nt heard about anybody that has drill a hole and had problems.

JB, I want to drill a hole into my Morewood Zula. Where do I get more info about the "April" thing

Listen to JB. SCOTT CR1 does not drain via seatpost. Only when you drill a hole

[The Drongo]

Just need to clarify a few bits here.

 

If you wish to drill a hole in Carbon, go ahead. Drill sharp and clean. REMOVE your BB first so that you can remove the waterseal tube, and avoid drilling a hole through same.

Carbon frame construction usually has a BB shell that is not 'linked' by holes to the other tubes, and is reinforced in some way. It may need a hole, a hole wont hurt.

 

Water will go INTO a hole a lot quicker than it will come out the hole,viz:

Warm BB shell with all the spinning - puddle, river, rain = water in.

Water in, mixed with grit and sy!t = clogged hole = no water out.

 

MAINTENANCE be the key. Learn to do it. It saves mega $$$$.

 

Beware the BUSHMECHANICS!
