Any question answered...

put my 725 genesis on a static trainer for a bike fit yesterday, being able to actually see the frame flexing like crazy was quite a surprise. Is this actually happening on the road or does the lateral movement of the bike negate this?

Yes. Unless you're doing a PA for a club or something like that then you're not going to need anything larger than standard lamp cord. If you try then you'll melt the cable and the sound will be shite as the conductivity will be poor.

With PCs you want to keep the data cable away from the power cable. It can cause fuzzy lines across your screen or blurriness.

Interesting comment about power interferance.

Is that a lie?

I've never seen power interference on a pc as much as I've never had to wear anti static wrist band...

Mind you I don't build them any more I have lackies now so the power is probably more, er, powerful than the hamster wattage I was used to.

VGA cables can be prone to fuzziness if run with mains leads.

When I was doing car audio it was a rule to run the rca cables down one side of the car and the power/earth down the other to minimise interference though

This is normal, especially when the bike is static.

Makes more sense for car installations, for reasons obvious to anybody with a passing knowledge of physics.

I'm looking for an exhibition on that I thought was called the body and contemporary art...

... But from searching that's clearly the name of an old exhibition.

Does anyone know which exhibition I'm thinking about?

^^ Doesn't everybody like hearing their alternator through the speakers?

Can anyone recommend a bike toolkit for around £30? I need to let Father Christmas know what to get me.

bargain just now

Perfect! Thanks :)

The threads in my Lezyne caught a lot of grit after repairing two punctures on a ride Saturday before last. This was after we had repaired two punctures with gas cyclinders; they were very impressive. I forgot the name. Which one's might those have been?

I use a GI Air Chuck and have a box of cheap threaded co2 canisters I got from the internet somewhere, 50p a throw or something.

These I assume are all the same in that they work like you had used a track pump?

(Sigh, this makes me miss benjam and his crappy tyres).

^ xmas for me sorted, hunting for co2 now. As long as threaded and 12g they will do right?

^yup

^^16g gets you up to about 120, 12g a little less. I carry 12g cartridges. They'll get you home but CO2 seems to escape the tyres fast, so you'll have to pump up properly next time you take the thing out. You get a little bit of flow moderation with that mini head, but it's pretty much a binary thing.

Spark plugs? Dizzy? Does it happen to vehicles with out spark combustion?

^yup

That fucking explains a lot!!!

First time I used CO2 the tyre went down to about 40psi within 24 hours. Since then I've always deflated the tyres completely when convenient and pumped them up from scratch.

Cheese, diodes, capacitors and ferrules.

CO2 is a smaller molecule than N2, so it leaks out quicker. Fancy car tyre places will fill your car tyres with "Nitrogen" instead of plain air for an extra quid, and the reduction in water content also makes the pressure more stable with temperature fluctuations.

I use a majority nitrogen in mine.
