So today I lifted my bike up and this happened...



So I'm thinking its water from the road some how gettin' stuck in my tube. If this is the case, should I be worried about having water just SIT in there? I've already noticed a rust-colored discoloration on my seat post... Will this cause structural damage on the rear thinner parts of the frame?

Ewwwww, I think the conventional wisdom is to drill a hole in the bottom bracket shell
Are those hollow axles? I assume thats where the water came from, I've never used them but maybe try and splosh it out when you take it inside (assuming it lives inside)

assuming thats just water

the water is dripping from small holes in the frame that vent pressure during welding. Nothing to be worried about, drill a hole in the BB shell or invest in some frame saver if your that concerned.


and for the second poster....no those are solid axles...... going to guess Fuji track formula loose balls...

Thew water came out of the little holes in the chainstays, ( the wheel side ) just a half inch or so infront of the track fork. ( visible in pic, not in circle. )

No need to drill holes in the bb, the water came out when you had the bike standing on the rear wheel, so... its actually water that has been sitting in the bb, that finally hadsomwhere to go.

this is why its a very good idea to "flip your bike" and dry your bike off after its ridden in the rain. To remove water from inside the frame I actually remove the seat post, flip the bike upside down till I get out as much as I can, then I stand it on the back wheel with the front wheel facing up toward the ceiling and let whatever water remains drip out of the vents, then I dry the whole bike off and let it dry without the seat tube on.

I usually just wipe my bike down, I've never tried to actually get the water out of the frame. I'll start doing this, thanks for the advice.

Mine does that too.

I have a drilled brake bridge and no rear brake, so I put a bolt through there to try and plug the hole.

Water still gets in. I have no idea how. I've got a cartridge bottom bracket, the seat clamp and post appear to seal that junction- there's the top of the seatpost I guess, maybe it's dripping off the underside of the seat down there. The headtube is obviously plugged. So, I'd say either the top of the seatpost or the holes it's dripping out of there are the likely candidates for entry.

Really, I'm just not that worried about it. I'm guessing the tubes will get a bit of surface corrosion on the inside, and that'll be the end of it. Given that the bike lives indoors and is dry almost all the time, I don't think there's any chance at all it'll be compromised by rust ever, especially not before it ceases to matter to me, due to it being hit by a car or stolen or something. If it bothers you you could always try some Frame Saver, as mentioned above.

water will get into any space, just give it time.
