Re: rear derailleur- XT or LS

Ah, yes, I see what you mean. I hadn't thought it through logically and objectively enough. I think I was still partly hung up on a mental image of ancient silly little mechs, with desperately weak springs tensioning relatively short arms, so incapable of coping with more than a limited range. But o...

Re: rear derailleur- XT or LS

There was an article on that in the latest CTC mag. You also have to consider the distance of the gear hanger hole from the axle (which is variable with horizontal dropouts.) The 20T to 34T is impressive but it is the overall capacity that you need the long arm for. If that 20T is part of 20, 30, 4...

Seeing and being seen

Well - primarily 'being seen'. Does anyone know of a reasonably-priced source of reflective tapes, stickers, etc? In view of how easily one cyclist can apparently 'disappear' from the view of inattentive drivers, especially (in my experience) against a confused background of other lighting of variou...

Re: BBC - "Cyclists are unaware of the risks from pollution"

I thought it had already reached that stage Jim. Seems a long time since I had a car I could do anything much on at all, let alone since the days when we used to do pretty much everything. Just another manifestation of the exploitative capitalist squeeze on individuals, between successive further en...

I can't remember the film well enough to recollect whether even Walter Mitty himself ever had a fantasy as wonderful as that! :P

Re: Basic chain and derailleur maintenance

snibgo, I'd expect it to act more like an easing oil, just stopping the links drying out. But any reasonably fluid 'proper' lube put on after should then find its way into the links by capillary action anyway. After all 'creep' properties are part of the essential function of a lube molecule - to fo...

Re: Basic chain and derailleur maintenance

Im sure i read it in a bicycle maintenance book that Diesel was an excellant degreaser and it also left a oily residue on the chain unlike petrol that would dry it out I have a plumber mate (my best man, as was, actually) who swears by diesel as a way of cleaning and freeing-up any old 'lump' that ...

Re: Basic chain and derailleur maintenance

As this thread has sprung back to life, I'll chip in with something that it occurred to me to wonder the other day (but hadn't when the thread was running initially). Much of discussion on this topic - (every time it rears its head again, I mean, not just this particular thread) - seems to revolve a...

God does not think he is a hospital consultant ?


Precisely so.
Tho I haven't asked Him - it seems a little frivolous somehow.

So - now let's look at Ozone'n'masks . Mark R, You say, "By the way I don't sell these masks! and I am not particularly promoting them, . . ", . . well . . if so all I can say is your faith in them is remarkable. I was in fact already aware of the abstract you linked. And have serious rese...

Mark R, I am not the one missing the point, and it does nothing to validate your arguments to distort my post by misquoting snippets of sentences out of context. a) The whole phrase was " . . gullible fashion victims and mudplugging MTBers without mudguards who . . " . I try to convey my v...

Re: BBC - "Cyclists are unaware of the risks from pollution"

Right folks, I too have done some digging. The official (Ref. 1 below) and unofficial (2) guidance explains that petrol engines are better in cities, mainly because they poison us less with PM10s. So far as I can make out, their reduced output of NOx is at least partly counterbalanced by their prope...
