I would say a 'tourist' is some one, any one who 'tours' around just for the pleasure of it. whether in a car on a bike or on foot, the journey length is irrelevant.

If your trying to get round a circuit in a certain time your not touring
If your trying to see how far you can go your not touring
If your trying to beat some one your not touring
If it involves any sort of business your not touring

Re: infinite-speed hub gear?

A continuously variable manually selected hub gear, for release "spring 2007" on utility bikes, based on a variable planetary gear.
i.e. instead of having gears 1,2,3 etc, you have 1,1.5 2.71818, or whatever intermediate gear you fancy.

‘Allspeeds’ use to make these type of box in Accrington. All right for motor driven applications but I'd be interested to know how they've managed to get rid of all the inherent friction in them.

Many a true word said in jest.

You have to be a masochist or broke to like riding a bike in this county in winter.

Were off for a quick pummelling by the wind on tonight’s ride.

Im pretty sure the permits are for technical purposes only to stop tow paths becoming public rights of way. I don't think they give a dam whether you have one or not.

You need to use different spacers

If its for an existing setup use your old spacers from your old block (you may need to drill/file the rivits holding it together)

The small ring with the spacer built onto it may need shimming out or use the old one. anway its been done, Highpath engineering use to sell spacers.

I agree with TC

If once the chain is clean and on the bike (but not relubricated) hold a link between thumb and forfinger and roll it from side to side along the finger as if trying to turn it inside out. If you feel and hear it grating and crackling then there are still bits of grit betweem the plates. A new or properly clean chain feels totaly different.

Once lubricated this feeling disapears. but the grits still there.

This is not because they need cars - they managed quite well with their bikes before, but because they see having a car as buying into a progressive Western model: it shows that they are successful.

Therefore, our power use might be small when compared to what the "developing" east are doing but our influence is not. If we cut down on our excesses and make "Greenness" the new fashion then there is a potential to influence those beyond our borders and thus change the world. The act of me recycling my newspaper may have little physical effect in itself, but me being seen to recycle _could_ be the key to making the planet a better place for people to live.


I would agree entirely with that, thats why I take stuff for recycling but I don't do it under any elusion that its saving on anything, I wouldn't be surprised if most of its not buried in someone else’s back yard.

I would like to see all packaging made of the same material making it more effective to re-use and forcing others to adopt the same policy of genuine resource saving.

Buying something from a well established UK firm only to find its made in the sweat shops of the far east is annoying but hardly the fault of those of us who 'are' manufacturing at home.

Any way I'm not on a buy British campaign, I’m talking about buying from sources that have to manufacture to stringent emission & energy controls be it here or anywhere else, and that will reflect in the price that’s paid for consumer goods being higher.

The fact that UK manufacturing would benefit from a more level playing field would be a side effect. And lets not forget that ultimately third world folk forced to work in conditions long since banned in the EC will also benefit from a healthier environment in the long run.

Its all relative. we think this countries bad because we live here and don't see it in comparison with the world as a whole. Nobody gets a mention on the news for installing thousands of pounds of environmental filter plant in their factory but the minute some one like ICI lets a bit of waste escape its spread all over the media. Not complying with your allowed emission consents is enforced very hard in this country especially if its a big company which is why its so obvious when something goes wrong.

Mr cheap bicycle frame manufacturer pours his waste solvents down the river and nobody says a word, Unfortunately we all have to live on the same planet.

I would agree our public transport is badly organized but our vehicles are still subject to stringent emission limits, which are wholly ignored in a lot of the world.


You can tell when its genuinely economic to recycle materials when they start paying you for it, like they have done with scrap metal since before Steptoe was a lad.

Why not try paying a bit more for consumer goods produced in countries that have to abide by strict and fully enforced pollution regulations with efficient power producing plants that make full use of all energy producing technologies instead of burning off whats cheap to hand.


Yes OK - so put your hand on your heart and name them


The UK for one. I know, I am hounded by them from dawn to dusk. Most of the EEC is bound by the same laws even if not totally perfect.

Europe does more for Global conservation than possibly any where else on the planet. Probably because they are more genuinely aware of the problem.

The places we buy our cheap bicycle frames dishwashers and cameras etc from have precisely zilch regulations (or any that are taken any notice of) on carbon emissions, environment, or small furry creature protection

An angle grinder :?:

Hmm

It’s not a safety issue. Ride it until the headset bearings need to be replaced. The corrosion causing seizing up of the components is very small and does not usually affect the strength of the material unless stored in damp conditions for a considerable time.

If you need to remove the stem, you can drift it out with a steel rod & hammer, place the rod up the hole under the fork crown (after removing the fixing bolt & wedge). Don’t 'fanny about' give it a good hard whack to shock it loose and avoid damaging the frame.

I can't see what use an angle grinder would be.
