    Small bits you could do on kitchen Scales. Whole bike on luggage type scales or fishing ones. If you were that sad anyway.

    Luggage type scale that the bike hangs from seems to be the one that many prople use.
    Either that or take it along to fat fighters every week in the village hall.

    1. Get on the bathroom scales and weigh yourself.
    2. Weigh yourself again, this time holding the bike in the air.
    3. Do some simple mathematics.

    My carbon fibre bike was build in a clean room on the space station. Their tests showed that both its weight and aerodynamic drag were negligible.

    Simple luggage scale does the job.

    You look at it with head inclined, step back, step forward, lift it in both hands (one on head tube, one on seatpost) then sort of raise and lower it in mid-air by about six inches.

    Then you put it down, look at it and do one of those Robert DeNiro quizzical faces and make a "Hmmmm..." noise.

    You don't need to know the actual weight; you just need to look as if you understand these things.

    Small parts - kitchen scales
    Whole bike - Park tools scale

    Means you can justify buying titanium bolts for everything because you can see the grams saved.

    Do you weigh the bike on the Park Tools scales once it's been cleaned in the ultrasonic tank?

    No, but air pressure has to be favorable.

    Weighing your new skewers on kitchen food scales then has to be confirmed with Park tool bike scales when fitted to bike. 8)

    I am getting Garmin Index™ Smart Scales next :D

    I looked on the manufacturer's web site to find out, said 'mmmm' then discarded the info as irrelevant as it was light enough.

    Debeli got it right. :idea:

    Its not Obsessive for me, just interesting.
    Bike tarting is far more of an obsession for me, and even thats just fun.

    Enve stem is the biggest weight saving I have spent per gram.
    Over £100 each at list price! Both of them!! :lol:

    Submerge bike into a large tank of water then collect the displaced water and measure the volume of the water. Since 1 litre of water = 1kg (on earth at least) then you can work out the weight of the bike. Far more accurate than a luggage scale....

    That would give you the volume of your bike, not it's weight, and besides your wife is going to be seriously cheesed off to find your pride and joy in the bath......

    Same thing, as long as you make sure all cavities are filled with water too.... frame tubes, handlebars etc etc.... Wouldn't be the first time a bike has found its way into the bath believe me....

    Damn you I was gonna say that :evil:

    Okay my tank would be full of beer and you must drink the displaced ale in pints natch!

    Hmmm bike weight in pints of beer I like it.

    No - what if your frame were made of lead? It would displace the same amount of water, but it would be much heavier.

    Personally, I proclaim mythical weight savings, directly proportional to the amount of money I have spent on something.

    For example, my carbon tubs on my CX bike save me almost 2kg.*


    *note, if you add this to all the other bits, most of my bikes are now under -16kg

    What if your bike is sensitive about it's weight and doesn't want to be weighed? :oops:

    Re the bath. Doesn't chopping the bike up to get it beneath the waterline kind of pose some performance issues?
