What is the lightest?

I'm looking at saving some weight on my rides and it got me thinking, which water is the lightest?

Is mineral water lighter than tap water, what is the lightest mineral water? (i.e. the one with the lowest number of minerals).

How about Brita filtered water?

    Really, if you're that concerned about weight, you can't beat an empty bottle.

    Do you think it would be best to forgo the water completely then? Do I not need to drink on my longer rides of, say, up to 12 miles?

    Go for bottled, but sparking rather than still as the air bubbles will make it a lot lighter.
    Carlsberg don't make cycle clothing, but if they did it would probably still not be as good as Assos

    Any particular brand? I thought about finding which is the lightest 'still' water then putting bubbles in that using a helium canister in my Mum and Dad's soda stream.

    what I do is grab green things as I ride and get my moisture from them, just like sheep do with grass. So save weight on bottles, cages and liquid

    Green things like a bottle of S. Pellegrino?

    I suppose I could ride in the rain with my mouth open.

    I ride home from work 16Kms or 10 miles, i then change clothing and bike and go out for another 45Kms or27 Miles and in all that time do not drink anything at all. I cannot see how you need to drink anything for a ride of only 12 Miles.Or is it just me?

    I really had a psychological obstacle to overcome when I took out a bottle with frozen water the other day- it was certainly heavier :shock:
    Where\'s me jumper?

    Water is, generally, water - often, mineral water is the same water that comes out of your pipes (in the UK, quite a lot of water companies sell their water in bottled form with fancy names on etc). The main difference is that the treatment requirements for tap water tend to be more onerous than those for mineral water (which, therefore, doesn't always meet the standards required for tap water).

    There are better ways of saving weight such as scraping the bits off your shoe soles which don't come into contact with the pedals, shaving your head, removing every other spoke, not wearing clothes; all as silly as worrying about how much your water weighs!

    Still, funny thread :lol:

    He's being serious Pat........A 750ml bottle of sparkling is a lot lighter than a 750ml bottle of tap water!
  • I think amputating your little toes and fingers will make decent weight savings. Likewise, cutting of one of your bike's seatstays; scraping the paint of the frame; ride on inner tubes only (get rid of the tyres).

    Forget the water, drink your own urine

    You won't be able to as you won't produce any if you don't drink as all excess moisture will go out via sweat. But you could wring out your jersey and drink that - also help with salt levels.

    That's considered "not good for you". You really should think about taking on 150ml per 15m of riding, so you'd probably need about 1.2l of water on a ride of that distance (assuming you average around 17-20 mph)

    Have you not discovered powdered water yet? Much better, lighter and lasts longer to boot...

    Have you tried carrying oil in your bottles? It's about 80% of the density of water. And the primary product of combustion is - you guessed it - water!

    So all you need is a lighter and you can make your own water on the move!

    In a few years we'll have the cycling equivalent of John Smith's 'widget', except ours will consist of a teeny spark plug in the mouthpiece of our water bottles to 'convert' petrol into water.

    I'm heading down the patent office first thing Monday morning.

    there are a couple of things that might help here. First, bubble helium through your water before you go out for a while, it'll displace some of the heavier CO2, O2 etc dissolved in the water. Second, put near boiling water in your bottles. Some of it will vapourise and you'll be carrying vapour round with you rather than liquid water. If you can stand it, try locating the bottle cages so you can rub them with your calves. That'll keep the water warm, again, making more of it vapour.

    the helium might make your voice go a bit squeaky, but you can always say you're recovering from some intervals, or you're trying a new seatpost...

    ...ahem...

    :wink:

    By the way the extra mass of the gas molucules in the sparking water will make it heavier. You need to boil out all extra dissolved gas molucules as gas is soluble. :wink:

    You need a reverse osmosis water filter to get pure H20. I have one under the sink. I paid 200 snots for it. My bottle definitely feels lighter with the RO in it :wink:

    I reckon, had I known this, my 12 mile 'long ride' could be done around .0008 seconds quicker.

    They'd better be ready at my local TT!

    Cycling home from work with rucksak and average racing bike i average 20MPH on my good bike average 21-22Mph never have a problem with it. My neighbour is a mountainbiker and he also finds it strange that i dont need any water. Next week 13th i am doing the Delta ride 120Kms for cancer research i do not expect to drink more than 2 x 750ml of water. Last year, beautiful weather i only drunk the same 2x750ml.

    Don't be so patronisong! What the hell makes you think you can come waltzing along, indirectly acusing me of being stupid!?! Do you ride a road bike??

    Surely you appreciate that lower weight = better performance?!?

    :lol:

    ..actually I rarely drink anything on anything under 12 miles. Most I do is 20 and thats rare thesedays. If I take anything its 500ml to wet the throat on a hot day.

    Just weighed my shoes - reckon I can save 2 seconds over 10 miles by leaving them at home and supergluing the cleats to my feet

    According to one poster here I should be drinking 150ml per 15 metres of riding so my longest ride (12 miles) I should be drinking about 193 litres or so.

    If you want to save weight then do what my mate did when we were kids

    I caught him on his Raleigh Equipe (remeber those - i ahd the super equipe with alloy, yes alloy, wheels) skidding.

    WTF are you doing? i said

    QWearing the tyres down to make it lighter he said.... :roll: :roll: :roll:
