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 ?. |

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 . |

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. |

I have a friend that does use helium on his time trial bike, but that said he does hold british time trial records. The only benefits are (a) in your mind, helium is lighter therfore I will be faster. (b) on acceleration, a lighter wheel will accelrate faster than a heavier wheel. However you will not have physic on your side for top speed, a heavier item has a larger mass and therfore can retain its velocity for longer. I hope that i didn't bore you to much :D |
