"Blast" from the past (BikeStream)

Cleaning out stuff this weekend, look what I found! Anyone else remember this failed product?! The one I tried had a penchant for having a mind of its own.

Is that Pollentier's rig from the '78 TDF?

Behind the seat. Was basically a bladder-based hydration system. Several have tried to make similar over the years. One of many examples: https://newatlas.com/veleau-bicycle-...-system/18435/

There's a piece or two missing in what I've got pictured here. I forgot this even existed. I hated it, but there were a ton of people who loved it. After half a dozen times of having it willy-nilly release at the wrong time, I gave up.

From what I have found on the duckduckgo, it's a pressurized hydration system for triathletes. The bulb would be used to pressurize the bladder, which went in that cloth sack and mounted somewhere on the bike behind the saddle. The only photo I've found suggests that it's meant to go on the seat stays just below the seat binder, and the drinking tube goes next to the rear brake cable. Like so:



It does look a bit like the rig my old employer had for fertilizing cattle.

Exactly, this. The downside was, if any part of that simple system failed, it would just release fluid until pressure was equalized. Failure could be anything from a pinch or bend to a leak (happened for me where the bulb meets the hose a couple times, best I could trace). No bueno. Wasn't worth the headache if you ask me, but some people swore by it.

Looks like something I'd want to be sure to leave behind after checking out of the hospital.....

I had one in the early 90s for one or two years.
I used it for triathlon racing only and only for water.
There was no way I was going to put anything with sugar in it and be confident I could keep it clean.
The funny thing I remember was when the bite valve got worn and wouldn't shut off immediately.
You'd get a mouthful of water, and as soon as you pulled your mouth away, the thing kept spraying, usually onto your face.
We called it the "Bikestream baptism".
It actually was kind of refreshing because it rinsed away the salt build-up around the face and eyes.
In fact, sometimes I would bite the valve to get a face shower primarily.
It was an interesting idea for triathlon back in the day, but prone to failure and not useful for long-course racing as it couldn't be refilled or replaced on the fly and had limited capacity.

I had one. They were most popular for time trials, duathlons and triathlons, where you didn't want to get out of your aero position to take a drink. I mounted mine to the saddle rails and seat post, similar to a tyre sock. However, due to their capacity, they were only good for about 40km. They were fairly popular but were replaced by simpler bar mounted hydration systems. I also consider them the inspiration for the Camelbak and many of the modern hydration systems.
