My bike has a leak!

snooks

Rode back from my GF's the other day in what can only be described as torrential rain. Dried my bike off when I got home, and sprayed some lube into the places I should, I hadn't moved the bike until today.

I've just flipped the stem over, wheeled my bike back to it's house and got my commuter out, wheeled the commuter top the front door and there was a puddle!...Strange ,the rest of the pavement is dry...hmmmmm :? Put my commuter inside and went back to my road bike, took it out and pulled it up wheelie style. from the two holes at the back of the chain stays came jets of water...in all about 1/2 a glass came out!

Now I rode through a few puddles, well the road was a puddle in places, but none were deep enough to get to the frame.

So,

Where could this water be getting in?

And should I be worried? or is this normal for road bikes to do?

HI there.

The usual place is just under the seat clamp at the top of you seat tube. Water sprays up from your back tyre onto the back of your seat post. The seat tube often has a slot cut into it to allow the seat clamp to get a better grip on your seat post. My cross bike has the slot cut at the front of the tube for just this reason.

Cheers, Andy

Also from the bottom of the head tube above the front wheel. The water collects in the bottom bracket shell and can stay there for some time (as you found out). I tend to tip my bike up after a ride in the rain to get rid through the chainstay drainage holes. It's either that or the water drains on the carpet on the stairs to my flat

Water will get in even the smallest of holes, after you get home hold the bike up as you did wheelie style then reverse, endo style a couple of times and then bounce front and back that should release most of the tapped water.

Because I have too much time on my hands right now i've taken to removing all parts BB and all every so often, I was surprised at how much moister was trapped, all just another reason why my road bike is now packed away for winter.

+1 for the single speed.
