Just in case anyone else thought, like me, that these no-name reproduction(?) aero water bottles from Ebay would be just the thing to complement your aero tubing or Lo-pro bike:

They leak. I tightened it as tight as possible, and it just leaks out a different side of the cap. Also- the quality of the plastic molding is pretty crude. Just don't.

Ok, for the thousands of silent forum readers following along , here is the closure to my story. I tried sanding down the mouth of the bottle to smooth out the flashings but it still leaked. Then I lucked out and got an original OGK bottle


The real OGK bottle has a much nicer slick/shiny finish and the base is Pearl looking plastic. AND it doesn’t leak.
So the moral of the story is don’t buy the cheap Ebay copy. Buy the real deal.

Did you try an O-ring in the cap?

TPL

use a o-ring

That's assuming that the cap is configured to hold an O-ring to good effect.

Making injection molds to high standards is quite expensive, so Chinese vendors selling lowest-cost items will have almost certainly not made such an investment.

I did once fix a leaking vintage bottle top using a thin gasket pirated from some sort of liquid container top (like windshield fluid or anti-freeze). I did the same trick to stop a snap cap on my truck's charcoal EVAP canister from leaking vacuum air, added some gasket sealant as well and it's been good for the last 24 years now.

This one looks iffy, too.


You have to be thirsty with this one. Taste is awful.


I actually need one of these.



This one had a rubber nipple with a slit in it.
You basically bit it. Gross, even at speed.

Are any of us still fast enough to justify the need for any of these?

Just wondering

That's a good one. There's the 'O.G.K. Japan' wording on the base of the bottle. That and the shiny finish on the bottle and pearlescent finish on the cage base.

I use them on my period-correct builds because that is what they came with. Shown are a Shimano DA EX Team-Miyata and a DA AX Pro-Miyata with matching aero water bottles. Other than that, all of my other vintage bikes have normal round bottles which I prefer.

Excellent point. I finally learned to efficiently drink while riding, and that took practice. In fact, after switching my focus to centuries, I switched bottles to use a certain top that works better for me. Once a real hydration protocol became necessary, bottle priorities moved up a couple of notches. Hydration became a technique, and it proved itself over and over, especially on a 230-miler.

Aero bottles are likely more of a fashion item. I’m sure they make a difference for a top level TT or tri, but I’ve yet to see a triathlon podium order determined by such a slim margin that all that made a difference in the middle stage.

George Jetson bottle.

Personally, I think those bottles are ugly af. That was a best forgotten era in cycling history (except for the Huffy Aerowind; that’s cool af).

Attempts to reduce air drag on a tiny area as a water bottle makes no sense when the rider themself is a giant wind sail.

So instead I'm going to compensate by deleting my helmet and my hair for aerodynamicy and weight saved.

T-Mar

I was thinking more along the lines of who can ride a lo-pro long enough to justify the need to fill the water bottle.

I had the Campy aero bottle bitd. I couldn't keep my hands on it... I never had a water bottle that I dropped so much and then ran over with my bicycle. Maybe I had a drinking problem. That's not cool. Of course, your mileage may very.

Another aero bottle to avoid is the one from Cobra, unless you just want it for display.
The plastic chemical odor and I suspect, taste that comes from those bottles is as bad as it can get.....
The NOS one I found for my Medici is so bad that it just always sat it in its box in my stash since I bought it years ago.

@icemilkcoffee

An O-ring sized just a bit big to fit snugly in the inside corner of the cap along with smoothing the lip of the bottle would likely drastically reduce or eliminate the leaking.

Everybody has a decent O-ring selection at home, right?

That's not meant for speed, but meant for comfort....rims look like they'er riding on fat tires".

Do not buy vintage aero bottles.

FIFY

No way they'd even take the time to make a new mold - it's almost certainly the original mold from Japan. I'd be thanking the seller for these; and providing feedback about what's lacking. Most likely they can't use the same plastizer as the vintage ones ... because BPA

Edited to say the eBay link shows them as NOS not repro?

Drillium Dude 

I've always wondered why I see so many negative refs to BPA when it comes to vintage bottles. I mean, check this out: BPA Facts

Or this: BPA Report

The truth is out there
