Re: Decibels

it's 25% of whatever was originally measured at 70. 70 dB is 10 to the power 7, Exactly. The Bel or Decibel is not a unit of measurent in itself, it is a logrithmic scale of comparison and so must always have a base unit to relate to. In this case the correct measurement unit is dBA (A for audio I ...

Re: Storing bike bags in box outdoors

They will grow mouldy if not used or aired regularly. Just on a saddlebag I would not mind because it will brush off, but over several items I would keep them indoors, on top of a wardrobe or under a bed for example, perhaps inside a suitcase which is being stored.

Re: Electric cars

Is that 300 miles at motorway speeds in the depths of winter with lights and heater switched on? Or is it 300 miles on a balmy summers day at a steady 50mph? I only use a car for distance travel, usually as it happens a 300 mile round trip, so the lack of charging opportunities and the time taken to...

Re: What chance of law on the roads when TV is pleading for motorists?

I get the impression here that what's being discussed is decriminalised traffic enforcement. You get a ticket for things like infringing a box junction and if you don't like it you have to argue the toss in front of an adjudicator. Guilty until found innocent. For a lot of people, it's not worth th...

Re: What chance of law on the roads when TV is pleading for motorists?

But where the signs are incorrect, fines are rejected/revoked when challenged. What Mr King seemed to be arguing for was a blanket first-one-free system - not just that motorists get one warning somewhere and then fined, but that each motorist is allowed to break each yellow-box or turn/entry restr...

Re: Hub dynamo comparison

Flange spacing on the SP is somewhat narrow at 50mm versus 62mm for Schmidt. Hence the wheel may not be as resistant to side loading, which may or may not bother you.

Re: Stay indoors?

Wind on its own would not keep me at home. Today it is raining steadily and has been for some hours, so I will not set out. If it rains while I am on the road that is fine, but I am unlikely to set out unnecessarily in anything other than light rain. I will go out in fresh snow, but it is only a few...

Yes. My point was that cyclists use bridleways as a specific exception to other types of carriage.

Re: Cycling on Footpaths

Normally, a bicycle is a vehicle and a carriage. However, it's not a motor vehicle or mechanically-propelled vehicle. I think the closest similar vehicle in law is a horse-drawn carriage. Not sure about that. I think it's closer to horse and rider. Both riders and cyclists have right of way on a br...

I have 8 machines, of which only 3 have rear brakes. When I get on one of those it is usual for me to temporarily lock the back wheel when braking for the first few occasions, until I recalibrate myself.

Sidi tend to be a narrow.personally I wouldn’t buy shoes I couldn’t try on, regardless of how cheap they are. Shoes that don’t fit correctly are expensive mistake.

Many years ago I had some Shimano shoes size 42 which fitted my size 8 feet. When I changed to Sidi I needed 43.
