| I once hear that Eddy Mercks ran with helium in bike tyres, has anybody tried this ?.
I know you can hire bottles of helium to blow up party balloons, it couldn't be that hard to rigg some thing up.
I just wonder how much it would alter the ride of the bike ?.

| i think in reality it isnt actually that practical. firstly as we all know from helium balloons helium can easily escape the rubber, and with the force that would be excerted on it, you may need to keep filling the tyres over and over.
secondly, im not sure it would lighten the bike much, as i cant imagine the weight of air in the tyres amounting to much.
that being said, if anyone has actually tried it, i would be really pleased to hear.

| If you get a helium filled balloon and attach a paper-clip or two to the holding string than you can usually make the balloon sink . So that's how much weight you will be displacing a paper-clip or two's worth , you'll gain more probably by having a hair-cut , hardly seems worth the effort .

| Not sure about helium, very small molecules, would probably leak through the inner tube. I work on race cars and we use Nitrogen, not for any weight benefit but because it is dry and contains no moisture. The reasoning behind this is that its easier and more repeatable when monitoring hot tyre pressures.
Never going fast enough on my bike to get any heat into my tyres I can't think of any benefit of doing this.
