Adjusting chain, water spills out when loosening pinch bolt

Hi all,
Has any body ever seen this. I was washing the bike. I just use a hose, bucket of water with some standard car/bike cleaning shampoo. I don't use a pressure washer.

The next moring, I wanted to check the chain tension and tighten if required. It needed a bit of tensioning, so I undone the pinch bolt, and some water started coming out of the pinch bolt hole. I'd say about 1-2 cup fulls.
I was wondering where would that water have been sitting before I undone the chain tension pinch bolt?
Thanks, Sprockets.

I would always clean the chain with a rag and kerosene or WD40 after I washed and dried the bike. I typically use waterless cleaner after I ride my bike and will only use soap and water when the bike is extremely dirty and needs to be thoroughly cleaned and waxed. Afterwards I always dress the chain.

I have no idea what happened to your bike. But I do recommend cleaning and dressing the chain.

If you are saying the water can puddle in the swingarm and is released per the pinch bolt, that indeed is a new maintenance and cleaning consideration.

Haven’t noticed that myself but I’ve also never undone the pinch bolt fully. Will check.

Yes indeed. I also cleaned the chain before lubing. I used WD40 chain cleaner, & I use a spray on chain wax. I find wax based chain lubes do not fling as much as other chain lubes.
Obviously the water pooled in the swingarm somewhere, and was released when I loosened the pinch bolt.

That's interesting I'm going to have a good look at the bike and see how the water got in there ? I haven't ever thought about it before.

There are holes in the swingarm people have dropped screws into when swapping out huggers and fenders.

My guess is water got in there.

Did you use a pressure washer?

This is actually an important notice regarding water pooling in the swingarm.

I am thinking about rain as well as washing.

Wish we could tell if this is an anomaly or if the swingarm really does have a pooling flaw.

My bet would be riding and simply moving the bike around would get rid of most of the water, not to mention the heat in that area would help as well.

Doesn’t sound like the op did anything hit wash and put it away.

Op, I see above you said you didn’t pressure wash, my bad for missing that.

Water will get inside the swingarm. I have experienced that on many occasions. I park my bike nose up, and after washing with pressure washer there will be water coming out of it near the rear axle. It propably does that in the rain too, but then there is water dripping everywhere and the ground is wet, so the issue with the water coming out isn't apparent.

Never thought that to be a big deal though. There clearly is a hole that prevents the water from gathering up too much.
