What type of....

[Gerry Attrick]

air is best to use in bike tyres?

I currently use air extracted from the Lincolnshire fields, but it does seem to leek out over a period, and that stuff from the fens goes flat. Would air from the Scottish glens be better for mountain bikes, or would that expensive French Riviera stuff that the pros use be good in the wet?

Someone suggested I use air approved by SimonCC, but I found it smelled of bull***t.

Also, is there a cheap way of importing it in bulk as the small amounts I have managed to import over the years has not gone far, and the VAT charged at import is subject to inflation?

I bottle all the hot air generated during meetings and I find that works well. Only downside is it then contracts as the temperature drops. Fortunately there is an abundant and renewable supply for topups.

I use Bel Air as supplied by the Fresh Prince.

Or there's the smaller version, which is OK unless you're lactose intolerant.
Baby Bel Air

You might think you're joking.......................but last time I was in Kwik Fit having a new tyre on the car I saw the advert for 'proper' air with all the water vapour and oxygen extracted that professionals use for their car tyres - supposed to stay at pressure longer 'cos the molecules are bigger and don't sneak out through the rubber so easily.

That was because it was possibly not 'air'. My local place uses another gas (cant remember which) which contains no moisture and other elements that affect pressure retention etc.

There's plenty of hot air in these forums sometimes

hot air, scented with marketing bullshit

The best air is of course the lightest air.

Light air can be gathered at heights over 60,000 feet as obviously being light it floats a considerable distance above heavier air.

Nitrogen !

Yes and if you use normal air it has very nearly 80% of it already mixed in!

If I get a p**cture I use the Sp'air.

I'm so sorry...
