Canardweb Posted August 21, 2011 Author Report Share Posted August 21, 2011 hey simon I understand to be honest we all have weird ideas sometimes weighting air actually isn't the weirdest thing I heard about our sport but please, don't take yourself or other people on here too seriously... it's a forum...it gets boring when things are too serious I am not serious. I just wondered you know if it was correct! I understand what you mean though. I dunno if i read this properly but if you are really that bored go out and ride your bike? I wish I could man.

ben_travis Posted August 21, 2011 Report Share Posted August 21, 2011 (edited) Isn't the volume of a tube (pi x r^2)/4 times length not pi x (d/2)^2 times length Edit: it's cool I'm a noob. I get a volume of 0.00495 m3 and density or air is 1.22kg/m3 so mass of air in the tire would work out to be 6grams?? Your calc was a little long winded. I agree with the majority though...really something you'd even consider? Don't you have other activities in your life other than trials??

Maxx Posted August 21, 2011 Report Share Posted August 21, 2011 I suppose the "1.6 bar" is the pressure in your tube ? In this case use 2.6 bars in the formule (atmospher pressure is about 1 bar) It results of a heavier weight. But I may be wrong also.

Luke Rainbird Posted August 21, 2011 Report Share Posted August 21, 2011 So do I... Haha Going on the way you seem to be posting in every thread you can at the mo I say you probably have more than enough time on your hands already... 8 Quote Link to comment Share on other sites More sharing options...
Filo Posted August 21, 2011 Report Share Posted August 21, 2011 Since you will be running no air in your tyres you should run no tires and tubes.probly save 2kg off your bike. Seeing this thread makes me glad I ride a bike that's +10kg. Riding with really tires is fantastic Quote Link to comment Share on other sites More sharing options...
Jake. Posted August 21, 2011 Report Share Posted August 21, 2011 Going on the way you seem to be posting in every thread you can at the mo I say you probably have more than enough time on your hands already... I guess but... When I'm on the TF, time flies, but if I spent my time measuring and calculating how much air weighs, I'd get bored much more quickly.

Gilbert Posted August 22, 2011 Report Share Posted August 22, 2011 wow, some people spend days on end playing cod and fifa.. so what if he wants to find out the weight of air.. its just something to have a bit of fun with 1 Quote Link to comment Share on other sites More sharing options...
Matt Vandart Posted August 22, 2011 Report Share Posted August 22, 2011 Well it's an interesting subject. But I don't think that drilling air is a good idea. Lolz. Simon You are a star bud!

number1spark Posted August 25, 2011 Report Share Posted August 25, 2011 hi, you could allways try nitrogen, its lighter than air and dosnt expand under heat. quick-fit inflate car tyres for £4. Quote Link to comment Share on other sites More sharing options...
MonsieurMonkey Posted August 25, 2011 Report Share Posted August 25, 2011 hi, you could allways try nitrogen, its lighter than air and dosnt expand under heat. quick-fit inflate car tyres for £4. 78% of air is Nitrogen.... Quote Link to comment Share on other sites More sharing options...
