black friday 2 46 728x90

My brother, Alan, in the UK is looking at buying his first road bike and is looking at THIS one.

Can anyone tell me though, why some bikes are sized using imperial inches rather than cm ?

Alan is looking for an entry level bike and wanted to spend a max of 600 UK pounds, so if anyone knows of a good bargain ( near the London area) we would be interested to know. ( Preferably 9 or 10 speed Tiagra, with a compact crank in a size 56cm)

standard Euro measurement?

I don't think so. Most bikes I have looked at in Europe seems to be in cm. Just the odd one here or there uses imperial ...

UK and USA still use imperial measurements.

Condor Cycles. The only option!

Perhaps you should go on an American forum and ask "why some bikes are in cm"

Or one could reply for Australia: Why are any bikes sized in cm, since centimetres are not part of the Australian standard for the implementation of the metric system?  (No intermediate units between millimetres and metres.)

Conversion of units is not all that difficult, really.  What is important is exactly what measurement is being described by whatever number and unit is given.

I would have thought if you were doing it regularly some sort of spread sheet would sort it.

Non standard units are a pest and make the straightforward complicated.

It could be worse if you are converting currency's  the conversion factors are not constant.

API rules the world

At the time that the French revolutionaries invented the Metric System, the devisers were so unimpressed with the complaint that base 10 was far less factorable than base 12, that they threatened to use base 11 (a prime (non-factorable) number) for the new system.

While the metre was supposed to be exactly one ten-millionth of the earth's quadrant, they made a surveying error, so the end result is the distance between two arbitrary marks on a certain bar, just as is/was the imperial yard.

That wasn't Franks bar was it?

hmm... imperial.. gallons and feet and ego..

hmmm... I wonder which nation that could be...

Martin, and then US and UK (and therefore Aus) have different barrel sizes. Also US, UK and Canada have different liquid gallon sizes; dry gallon sizes are another matter.

In 1999 I was surprised that the measurements for the spacecraft mission were not tripled checked.
