Re: slowing down on hills - some 'O' level physics

I would also add a little observation that my heavy wheeled bike with its heavy 1.75" Marathon tyres can store a bit more of my energy from descending the hill in the rotation of its wheels. that is true, but you get no examiner's credit as rotational energy doesn't come on to the syllabus unt...

Re: Nice Sturmey Archer trigger

I was really pleased when I found out those shifters were available. I have an irrational hatred of twist grips, and had been convinced at one point that was all that S/A offered. Still have the admittedly decent enough shifter my bike came with http://www.sjscycles.co.uk/images/products/medium/stur...

Re: Three Word Story Game (again)

Captain Beaky and his upright trike blocked a chicane in the sewage treatment pipe. Flushed from playing poohsticks, knock down ginger kittens roasted over a Kelly's kettle whilst the mice wondered glumly why the clock struck back while Darth piggy wiggy whistled Jethro Tull. The Top 40 will include...

Re: Book on bike maintenance

Richard's Bicycle Book / Richard's New Bicycle Book - I have seen these on Amazon/Ebay for as little as 1 penny + postage. I would definitely recommend this too. My brother got a copy from a secondhand book shop ages ago, and while it's pretty dated in places, there have been revised editions and a...

Re: Joggers with headphones

I love music, but I never feel comfortable listening to it on a bike or walking about, because so much awareness disappears. On top of that I can't stand the little earphone plugs that go in your ears for about 30 seconds at a time before falling out. I always feel uncomfortable passing anybody, be ...

Re: Sacrificial Anodes

On a different note ,if you look at old Land Rovers where ever the ally comes into contact with steel ,over the years this corrodes away.Dissimular metals +water. I kno that alot of Land rovers do spend alot of time under water :) but they do come out for air most of the time :lol: I always thought...

Re: Maximum heart rate

I think DP by DT is more or less mathematical speak for "change in pressure vs. elapsed time" or something like that (steepness of the curve?) DP by DT is lazy speak for that yes. Technically it isn't steepness of the curve, but can be used as an approximation. The more accurate steepness...

Re: Sacrificial Anodes

I too remember something about it when I did GCSE, or maybe it was key stage 3, Chemistry. I didn't pay much attention though. I was always too busy inventing silly short corner routines for hockey :)

Re: Sacrificial Anodes

You can buy "marine grade" SS nuts and bolt of course and they are rustproof ........... but cost more. I read an article in "Classic Bike" magazine that recommended against using marine grade steel for anything load bearing, as it is not as tough as standard grades of stainless...

Re: Sacrificial Anodes

I'll have to agree with mrjemm and simonineaston, sacrificial anodes only work in underwater, preferably saltwater environments. They are used there because other forms of protection wear away too quickly. They can't work in the air because air is too good an insulator, so there is very little poten...

Re: TYRE PRESSURES

Well if that is their wording you probably should pursue a refund or a replacement from whomever you bought it from. Sidewalls can also crack as rubber degrades with age, but as these are supposed to be heavy duty, low maintenance one might imagine this would take longer than usual. How old are the ...

Re: Road Rage Assault on Cyclist

It was a personal experience of mine which was very similar to the one portrayed and I could hardly say I expect a prosecution when In my case I did nothing about it. Why? I too have been in a similar situation and defended myself with the bike(I hit the assailant with it).If someone comes at me wi...

Re: Jury fails to reach verdict

Another other red light anecdote I was waiting at the lights at a junction close to my flat about six months ago, when a driver broke the lights in one direction, and a cyclist in another (it is a X junction with poor visibility) Oddly they both seemed very angry at the conflict, waving arms and sho...
