And on e-bikes they would hardly be a disadvantage, any added weight and wind resistance overcome with the added assistance. .

I'm sorry you feel this way, but you are mistaken, the regular members are more often noted for the way they disagree! The reasons for the group of likes are expressed in the thread, unconventional methods of signalling are potentially dangerous through being either missed or misunderstood. I...

Agreed, it isn't. The alignment of belts is hyper critical, if it's not perfect they will either run off, or if side-guarded against that will chew themselves to ribbons. But if set up properly they do have the mentioned advantages that many value highly. Given my experience of them, I'd be...

Proving my point Tony! cl and kg are divisions and multiples of the basic measures, proving beyond any argument that the basic measures fail to match most human day to day needs. Imperial measures do match most daily needs, which is why they persist as I've shown above with the facts from...

I would say so too Rob, given my experience or working with toothed belt drives for years on static machinery and their use in cars. But life is not the only advantage, the much greater one for most is the freedom from the tyranny of lubrication and cleaning that bedevils chains. .

That perfectly describes the choice of the earth's circumference choice as a metric basis Mike, arbitrary! From there a logical system was developed which very much suits the specialised fields like science, but as I've again pointed out, I'm not arguing otherwise. I don't know how many times...

There are two differences, the belt is slightly less efficient, regardless of what their manufacturers claim, and it's tensions are normally higher to ensure no slippage. .

Mike, but you really need to start by accepting the metric system was based on an arbitrary measure as I've already said, that is a historical fact. Then you also once again try to change the terminology, after previously arguing it's consistency, now you bring in adjustment and complexity...

Actually I do and always have done, and it's precisely in cooking where the inconvenience of metric merasures is exposed, ingredients expressed in hundreds of grams rather than the far more convenient ounces and lbs. .

Not only body parts, but what we use. As I remarked earlier, using BAR for tyre pressures is daft, it's scale not relevant to the need. Likewise but opposite, the gram is far to small in daily use, too often having to be expressed in hundreds and rarely useful singly or in tens. And how many...

The power won't cause any problems, some of Harley Davidson's huge engined motorcycles use these toothed belt drives and car camshafts are commonly driven through them. So it's a very sensible maintenance free choice, only the possibility of not having a spare locally eventually being an...

I agree and would never have disagreed with that premise Mike. My contention only had regard to the human scale and needs. The USA have probably made the best choice, metric for science, engineering and finance, and a form of imperial for much of everyday life. .

Once again I have to disagree, the metric system was based, not on tens, but on an arbitrary factor, the circumference of the earth. Then the construction of a very logical system from that basis makes every measure arbitrary, regardless of it's undoubted consistency. At no time in the...

I think all sports types and youngsters are being ripped off by this industry with their silly claims for ordinary ingredients. They'd do a lot better with a healthy, widely varied diet of food based on fresh ingredients, leaving out these sports offerings and other junk food. .

Not so Mike, and you're confusing consistency with arbitrary, the latter having a quite different meaning. I've used metric in engineering from my mid teens onwards and freely use both all the time, depending on which is most suitable at a given moment. I also convert on the fly when necessary...

Yet I bet when he got home his mum greeted him with "Look at the state of you!" .

Never more true than with the Hillman Imp of yesteryear. After changing it from the intended twin-cylinder engine to a larger four, it was very back heavy and tended to lift the front over bumps. So the standard tyre pressures were 15 lbs front, 30 lbs rear, to keep the front wheels in contact...

Here's the link John. Perhaps the administrators will pick it up and accept your suggestion. .

Here you are with what looks like that link .

Here's the most effective lightweight kit, weighing only a few grams. Swallow these each day: Erythropoietin Bromantan Ephredrine An NSAID Creatine Then you'd go, look at how well Lance Armstrong went! .
