Hi i used a zefal magnum when i was touring solo in January from Adelaide to Perth. I choose it because it was the biggest bottle i could find that would fit in a standard cage.
This is the worst bottle i've ever had. it leaked the whole time. Firstly you have to screw the top on so tight just to get it to seal that when you need to unscrew it, it's almost impossible. The nipple also leaks air when you're sucking on it so it's like sucking on a straw that has a hole in it. I lost about 1/4 of the water from it whenever drank from it so i gave up and just used it to refill my 1.5L bottle i had in a Topeak ModulaCageXL.
You naturally squeeze a bottle when your drinking from it. When doing this to the Zefal Magnum over time it stuffs up the roundness of the top where the thread is so you end up cross-threading it when putting the lid on. This lets a hell of a lot of water out.
I hope that I am the only one that has had this experience with this bottle.
Has anyone else got any feedback on it?
