[quote="Brucey]With Schrader valves ...It is not considered 100% safe to have just a spring holding the valve shut [/quote]
Bit of a surprise here!
I realise that the spring would be important when deflated, but I always thought that at working pressures it was the air that kept things airtight - splendid example of self compensation.

Re: Anyone done carbon fibre?
I was into kayaks in the 80's and remember looking at ads for bespoke boats, polyester resin with combinations of glass, kevlar, and some other exotic material (aramide?) that was even more expensive. Kevlar cloth, which I believe is made from the same polymer as Dyneema, was supposed to produce a stronger job than glass,but one reason given for not using it throughout was the difficulty of getting a satisfactory bond with the cloth. Very hard to wet out IIRC - something to look into?
TBH, I wouldn't have thought the choice of reinforcing would save much weight on something like a mudguard - usually most of the weight is resin.

Re: LBS v Online v Online-Physical
I'd like to drop in to a local shop for most of my requirements, but of the two that I regarded as "serious" bikeshops, one retreated to their other site nearly twenty years ago. It's about 8 miles away, its a horrible ride and there is nowhere to lock up to when you get there. I don't get there as often as I used to. The other one closed down this summer and has reinvented himself as a mobile service unit. The thing about bike shops is that I like to do my own maintenance, and these days I can usually manage most of it. People like me must be a nightmare for them!
FWIW I'm pretty close to Wiggle's physical presence I was excited when I heard they were coming here, but all for nought - no counter service, not even for click and collect. And, like Chain Reaction they are of limited relevance to someone chugging around on a lowly 8 speed!
I've used SJS quite a bit. Say what you like about them but they keep lots of spares and stuff you might not have known about and they have always been pretty good at replying to questions of the "will it fit my..." sort. Never had much contact with Spa, although I have three of their wheels, but always consider them because they do at least support the type of cycling I engage in - riding around and touring and they are cheaper if they have it.
I think that they both count as "quality" and as such deserve our support. Retail generally has moved further away from our homes and on to t'net, local bikeshops likewise. As long as there is somone willing to supply spares...

Re: An easy to use track pump head?
Bother! Fully intended to specify Schrader valves and road pressures, but it was getting late...
I've never understood how they became so popular for bikes - why have a bigger hole in that narrow rim, than you have to? I only have one bike now that uses Presta, I have an adaptor for it that sort of works, but usually I use its onboard Zefal HPX - which I can handle quite successfully. Hhmmm. Food for thought...
At the moment, I let down the Brompton tyres, by way of checking the pressure about twice a week. Definitely not a Team scale user!
I currently have a twenty odd year old Silca. Pump works fine, but apparently when it needs a new washer I will have to make one as they changed the bore. The original hose has been shortened over the years and is now too short for convenience. Currently has a Zefal lever action head which is the focus of my current dificulties.
If I bought the Lezyne flip head I would obviously need a coupling and hose as well, at a cost over half way to that of an entry level pump, and with no real idea about compatibility. Perhaps, after all, its just time to buy new - If only I could afford an accountant - I'd just get me an air line!

An easy to use track pump head?
Can anyone recommend a decent quality track pump head that is easy to use?
I'm struggling to use the one I have because of a problem with one thumb that makes it difficult to apply enough squeeze to get it properly seated while flicking the lever up with the other hand. Not much better the other way round. I end up letting all the air out before I've got it sealed on. I suppose I could go back to a screw on head , but there do seem to be some quite fancy looking heads available at SJS. At a price. Are any of them particularly user friendly?

Stumbled across this during my market research: https://wooshbikes.co.uk/?rambletta
£899 according to their shop page, but still 20kg
No direct knowledge, but the company appears to have a decent reputation in these parts.

Re: Card Payment only, No Cash
Not as yet, but I think you , well, we need to resign ourselves to the likely disappearance of cash in the foreseeable future. To the banks etc cash handling requires too much expenditure on premises, wages and physical security. To Boris and the boys people with cash are just loose cannons. Could do anything anytime - and thats obviously just Wrong. Except for those who have so much that Swiss banks will put out the red carpet...

Re: Porridge: love or hate?
Porridge was required eating during my childhood. My father would make it overnight in the small oven of the Rayburn. When he took it out he would add a vast quantity of sugar. I ended up being unable to face it.
These days I can manage it when served with salt and a bowl of cream
But I prefer my oat ration raw with chopped fruit, seeds and nuts and served with semi skimmed and natural yoghurt.
Talking about it has inclined me to pencil in microwave scrambled eggs and coffee for tomorrow

In practical terms, I doubt it. Yes, there is a requirement to report accidents involving an injury to the police, but as I understand it the purpose of that requirement is essentially about not wasting police time. As long as you make yourself readily identifiable and locatable and don't try to deny your involvement I doubt that anyone would be that bothered about enforcing it.
Especially if you spoke to someone in a blue uniform who could have been taken for the real thing.
