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/ |

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/ |

Sounds wonderful, since I got this MTB I've made daily tours and covered most of the city, but really just found one great place to go, and it is only some 25km! But I'll dig deeper and perhaps find ways between cities as well that aren't on the big roads with all the cars. I have 2*650ml bottles on the frame and a rack that takes 10kg. I usually lash a drybag to it. You panniers look interesting -- underground experts united http://user.it.uu.se/~embe8573 |

But I'll dig deeper and perhaps find ways between cities as well that aren't on the big roads with all the cars. Yes, do that, it's fun. On some of the routes I use 25km can take 3h and that's assuming a fit and skilled offroad rider. Some are easy, like this from Placerville to where I live and which is the only bike-friendly connection: https://www.youtube.com/watch?v=Z_T2c4AXaCY It's probably even smoother in Sweden. I have 2*650ml bottles on the frame and a rack that takes 10kg. 10kg can quickly become 50kg for a second when you bang down a drop-off. I almost found out the hard way. ... I usually lash a drybag to it. You panniers look interesting They are the smallest ones I could find and suffice since I don't do multi-day trips. I use the same on both road bike and MTB so switching bikes with tool kit and all takes just a few seconds. The rack has a loading platform to which cargo can be strapped but most of the time it's just the little trunk riding up there. Key is the diagonal strut, a "false bottom" and a flexing Perspex (Plexiglass) plate pressing down the pannier hooks. Before I had that the boom of the rack began to buckle on rough terrain under heavy load. This is the stuff the bike industry just doesn't understand and the reason why many offroad bike-packers have their MTB loaded too front-heavy. You have to build it yourself. Luckily one of my biking buddies is a machinist and has an industrial grade milling machine. -- Regards, Joerg http://www.analogconsultants.com/ |
