Because they aren't just used as a shortcut for multiplying numbers.

True - you can divide with them as well!

They're also used for logarithmic units, and solving exponential equations.

What data does it provide?

See their FAQs page here.

I didn't find any mention of it measuring metabolic rate.

I recall an article in the CTC mag, they were reprinting, or quoting from, an article from the days of penny farthings: "Drink before you feel thirsty, eat before you feel hungry, and ride well within yourself for the first hour".

James Clerk Maxwell discovered electromagnetic waves using pen & paper, and maths.

I used to get that quite a lot back in my cycling days, but I haven't had it for years.

In the same vein may I suggest trying arthritis in your feet.

In which case it's the arthritis that's hard on your feet, not the cycling.

I've never ground to a complete standstill on the bike, even when I ran out of food, but there were a few occasions when I felt very nauseous an hour or two after finishing, and the feeling went after eating. Generally, if I'm riding more than 30 miles I try to stop every hour and eat about 250kcals. I don't get hung up on eating specific foodstuffs that aren't going to be available at any old village shop in the middle of nowhere, or anything that's expensive.

Whether they are or not, injuries aren't a reliable metric for measuring risk because the threshold for recording them is subjective, and varies according to the manpower available for collecting the data.

I cycle on traditional rat traps (MKS MT Lite) and have never owned a pair of cycling shoes, or felt the need to. For years until they stopped selling them my preferred shoes were Stead & Simpson's Hobos, but my last shoes were a pair of very thin soled Hush Puppies. By the time my shoes are worn out, the only part of the sole that doesn't still look almost new is the hole under the left big toe where I put my foot down. How anyone could think that cycling is hard on your feet is beyond me, you're only carrying a fraction of your bodyweight, and on a surface that continuously pivots to align with your sole. Try fellwalking.

Someone once posted a picture on here of the top off one of his bottles with the nozzle removed, and it was full of block slime like you see when cleaning out drains. That convinced me that I'd made the right decision to never put anything other than clean tap water in my bottles.

Not by a long chalk, it doesn't.

Heck, by now I've probably dropped my current main bike on myself while pushing it more than I've crashed it.

People don't see it that way though. In pedestrianised town centres I prefer to ride at~3mph with my hands on the brakes because it's safer, and I can stop quicker, but I've been told to get off and walk even by other cyclists.

Wheeling the bike is a PITA, there's no easy and comfortable way to do it.

mattheus wrote: ↑9 Apr 2024, 10:44amDo you or your mum know how many pedstrians are killed or seriously injured by drivers on pavements?

Of all the pedestrians killed whilst on the pavement, 98.9% are killed by cars, 1.1% by cycles.

There are two circumstances when the brakes generate no heat at all:

1) When they're not applied
2) When the bike's not moving

Sometimes you can get close enough to the former, but you can always get close enough to the latter.
