how long does water stay OK in a plastic bottle?
How long does water stay OK in a plastic
bottle? Here [1] it says 2-3 hours! Does it really happen that fast? And what is it that deteriorates? Will the movement of the bike preserve the freshness for additional time? I just bought two bottle holders from French Zéfal and installed them. I noticed when you do not have a bottle in them, the plastic arms are too close so they hit each other and make an annoying sound. But just cutting off a small part of one of the arms and it is fine. The bottles are also from Zéfal. 650ml, BPA free. Seems good. [1] https://www.quora.com/For-how-long-s...lastic-bottles -- underground experts united http://user.it.uu.se/~embe8573 |

Once the bottle is opened bacteria begin to grow in it. That's why it says 2 to 3 hours. However many bicyclists drink water (usually municipal tap water) that they've filled their water bottles with. That water has a longer life because of the stuff the municipality puts into water to purify it for human consumption. Btw, cutting the lips off of your bottle holders may cause them to not grip the bottles as securely as needed to keep the bottles from being ejected from the holder on rough surfaces or panic stops. this is more likely to happen with 750ml bottles than with 500ml bottles.

Cheers Two to 3 hours seems overly cautious to me. Pure water is *very* poor in nutrients. Whatever might grow after being fed with the bit of your spit that makes it into the bottle can be already growing in your mouth. Given enough time (weeks or months), some mold might grow, and to prevent this I wash out the bottles with dish soap and hot water after use. The municipal water supply where I live (Zurich, Switzerland) isn't chlorinated, so I wouldn't expect any difference between that and bottled water. Near the mountains there are lots of high-altitude summer pastures ("Alp" in Swiss German) with a fountain fed by a spring. I often refill water bottles from these. I always use anodized aluminum bottles like this one: https://en.sigg.ch/wmb-sports-white-touch-bottle . I switched to these back when plastic bottles always gave the water an unpleasant taste, although that might not be a problem nowadays. Ned |

I switched to these back when plastic bottles always gave the water an unpleasant taste, although that might not be a problem nowadays. I use a plastic drinking bottle, one or two stainless thermoses plus in summer several re-filled PET bottles (the cheap "disposable" ones). On long MTB rides easily five liters. Even after non-chlorinated water has been in any of those for a whole day I never had anything taste funky. We strip the chlorine out via a filter in the kitchen drinking fountain. -- Regards, Joerg http://www.analogconsultants.com/ |

How long are those MTB rides? So are all day, usually five to eight hours. ...Did you put a third bottle holder below the down tube? The MTB has no space for even one bottle holder on the frame so there is one holder for a 28oz (about 0.8l) on the handlebar. After all, every American vehicle needs a cup holder :-) The rest is all in the panniers and the trunk: http://www.analogconsultants.com/ng/bike/Muddy4.JPG -- Regards, Joerg http://www.analogconsultants.com/ |
