Canberradude: The polyethylene bottles become extremely plastic-tasting after a while. Makes them useless for more than a few rides. I prefer PET for this reason, like the PUMP type - very squeezable and reusable.

I just had a quick look at one of those objectionable bottles and it's got your BOA logo underneath.

Look at their website, the first page (if you click on sports&recreation) shows a roadie they sponsor.

I realize you said it was your opinion, and Im not saying you opinion is wrong... Im just wondering why you came to that conclusion.

I think it's more of a style issue than anything else... mountain bikers hit more jolts and bumps that can knock regular water bottles out of their cages so camelbacks are very practical. Road cycling style these days is based on the racing scene, where due to whatever reason they generally don't use camelbacks (weight? With water stations maybe they don't need to carry that much water with them?). Look at all the recreational bikers out there in full kit vs. plain jerseys, etc... people are just following the style of the day.

I say if you want to use a camelback, use a camelback... you might not win OCP points but who cares. At least you will be well hydrated and won't have to worry about finding a decent water bottle that doesn't leak.

Hey JUR,

with out trying to put you off, you should definately NOT be re using PET bottles. They are not designed for re use and actually have poisonous carcinogens in the plastic. PET is designed to break down eventually and if you keep re using them the carcinogens will enter your blood stream, not pretty! If you want to not have LPDE become plastic tasting you need to make sure you regularly wash them in the dish washer on the top shelf. Most people neglect this.

OK, I will try washing the one bottle that I have left. I have tried washing before with zero success, but not in the dish washer. Unfortunately I have retired almost all those ones I had to chain washing duty.

Can you back up the PET re-use issue with some sources? And with plastic-tasting poly-eth, what about those plastic molecules entering my gastric system?

*Please note that these are made from LDPE #4, which is widely considered to be a safe plastic.


The same Nalgene bottle caused me to crash and break my elbow last week. That cap was tight and I needed took both hands off to open it, lost my balance, and came down on my elbow cap.

I'm sure my lack of balance played a bigger role in the crash, but hey, why not blame the bottle :D

I will have a look at work tommorow, Im sure I would have some info somewhere on PET. Polyeth, be it high density (hard) or Low density(soft) doesn't break down like PET so molecules wont enter your blood. Im not trying to turn you off it I'm just saying that if you wanna use PET bottles to replace them on a regular basis, weekly if you can. The majority of people arent aware of the dangers, I wan't either until I worked in the industry.
You'll notice that PET gets softer the longer you have it, thats because it's breaking down and needs to be thrown away, which is the use it's intended for.

Canberradude 08-21-05 09:27 PM

Hey Jur, here is some info for you. It's kind of long so sorry about that but hopefully this will help you.

That is odd, you'd think anything being used to carry something for human consumption would be free from carcinogens. I'm skeptical about that claim that after time the bottle breaks down and can introduce carcinogens into your body.

jur 08-22-05 12:47 AM

I looked into this just then, and it turns out that email is a hoax. Reusing PET is OK.

See for example

Your instinct was right on target. :)

Canberradude 08-22-05 03:25 AM

It certainly sounds like they have done their research. Im sure my boss would be interested in seeing that info, she just forwarded on what she had but has been in the industry for over 15 years and they know their stuff.
I think well just have to agree to disagree on this one, I'm obviously not going to support the use of PET because well, I work for BOA and I just don't think they look very good in your cages. It's going to sound extremely snobby (this is cycling after all) but I don't want to put a 1$ mount franklin bottle in the carbon cage of my $6000 Caad 7 R3000 because normal bottles look and function a lot better (and our metallic blue matches my frame!). Just my opinion though and I am happy to admit that I am a lot more snobby about this sort of thing than most.
Happy Riding

It wasn't 15 years, more like 3-5 years max the PET hoax has been circulating.

Perhaps BOA could consider using PET on a line of bike bottles?

aham23 08-22-05 07:55 AM

i too use the polars. two of them. i keep them in the fridge until i ride. they are excellent at keeping the drink cold. once you get to the end it is hard to get that last bit out. i normally take the lid off at that point. later.

snoboard2 08-22-05 10:56 AM

hmm...thought it was dihydrogen monoxide;) gotta specify the number of oxygens

Just an update... I broke out my polar bottle for my weekend ride and it wasn't bad. No leaks and it sure was nice having cold water for most of the 38 miles (I only had one and refilled a couple times on the way... if I had two I'm sure it would have kept cold for the whole way). I still wouldn't mind one of those sure shot spouts, but until I find one I'm sticking with the polar!

Caine 08-22-05 06:44 PM

I had a couple of the Nike bottles and while relatively soft and easy to squeeze, they ultimately split and began to leak where the rubberized panel in attached to the translucent main body. This was two summers ago so maybe that problem has since been solved/fixed.

Canberradude 08-22-05 09:16 PM

What I meant to say is that my boss has been in the industry for 15 years. We don't have anyplans to go in to PET in the future. We actually have a plastics company which moulds our bottles in Sydney and our specialty is the printing. Pet bottles are harder to print on due to the thinner and crushable plastic which is why you see most of them with stickers and not ink printed on.
We are at the higher end of the market so quality and long life our main concerns and you don't really get either with PET.

Cheers
Jason
