i've a bit of a problem in keeping hydrated whilst cycling.
if I use a bottle & cage, the water freezes super quick. I'm thinking of using a hydration pack but beginning to think that will not be without problems either.
anyone any advice/experience of keeping water in a liquid form in temps below 0?
Use a Camelbak & blow it back up the tube after each drink
Use a hose insulator? [url= http://www.lezyne.com/index.php/products/bags-packs/hose-insulator.html ]Clicky[/url]
A vodka mixer always works in mine...
Would an insulated bottle that keeps cold/cold and warm/warm also keep cold/unfrozen?

Get a bottle with a good seal and put it in the cage upside down.
Works for me in the 'Puffer.
Camelbak and I keep the tube down the front of my jersey (but on top of my baselayer). Worked fine in the -7 degree forum ride last year so unless it got much colder I'd be inclined to keep using it.
could you pressurise the bottle?
say to 10GPa? 😆
+1 for Uplink, although remembering to do this each time is easier said than done.
If you've got the space, stick the camelback under your jacket, so it shares your own little micro-climate, plus blowing back.
i fill mine with boiling water . I am lucky to have the insulated tube , and its nice and warm 4 hours after leaving home. Alot easier to glug when its cold and encourages you to drink.
uplink is spot on, it doesn't need to be all that cold to freeze up a bottle's workings or a camelbak hose but it needs to be very cold indeed to freeze a whole reservoir, so blow it back in and problem solved.
From many years of backcountry snowboard experience, none of the Camelbak type insulators / blowing the water back really work. You always get left with a wee bit of water in the bite valve. That then freezes solid and you're screwed.
For snowboard stuff now, I just carry a water bottle in my pack, never had it cold enough to freeze that.
