This never occurred to me before

...probably because my normal route finishing points (home, work) are uphill.

But on the last day of our holiday on the Fermanagh border, I went out for a 40 odd mile spin in pouring rain. It was then time to load up and head home: as I lifted the bike into the caravan, a huge amount of water poured out of holes that I'd never even noticed before on the underside of the chainstays.

Did it all get in through those holes?

Think it can get in down the seat tube sometimes

I used to have a pair of Campagnolo Vento's which would fill up with water. If I'd done a TT in the rain, I'd take the tyre off and the water would pour out of the valve hole.

Didn't Boardman's "Athlete's Hour" record fall to someone who used an extra heavy back wheel? Hardly in the spirit of the rules. How do your TT times in the wet compare to in the dry GreasedScotsman?

Spray off the back tyre going down the seat tube, probably. Or else, if you have a saddle with a hole in it to protect the family jewels, water running off you into the tube.

I turned my tourer over once in a rare fit of fettling and about half a pint of very rusty liquid poured out of the inverted seat tube. At least I know that the bottom bracket seals were working properly

I don't think my TT-ing was ever consistant enough to gain any useful information...

FWIW the most common reason for ultralight steel frames failing was corrosion of the chainstays just behind the BB shell - I've heard of 753 frames failing in a 12 months
