When it comes to wheel size our Biggs is like the princess and the pea. 700c is ok, but somehow not quite right 
700c have a diameter of 622 mm
27" have a diameter of 630 mm
There is an 8 mm difference in the rim
They tyre size will make more of a difference than the rim
What amuses me more is that as a youngster them new fangled "Mountain Bikes" started using them 26"(559) wheels as the smaller wheel allowed a stidffer and stronger construction. The old guard tourers etc stuck with their tried and tested 700 C wheels
Then along came a new and far better system.... the 29"wheel, and the 29er fashion.
Ironically the 700c size is a 622mm diameter as is the 29er!
A superb piece of marketing as "new" a wheel size that has been around for years and predated the mountain bike

MTBs as they started to evolve in the UK by Geoff Apps started out as 27" in his early experiments, and 650B with his first production machine, the Range Rider.
In the states there original genesis was from Cruisers, which were 26". As people started to develop purpose built bikes they stuck with that size as it was considered a children bike size, and therefore attracted much more favourable sales tax rates. The stiffness was just a Billy bonus.

I remember when MTBs first came out. I used to pass a guy on my way to work most mornings on one of them. He was spinning like billy-oh at about 10mph as I cruised past at 25+ on the Carlton.

The Carlton has a 7/8ths tyre on the front.
That is simply masochism.....

Fitted to the 'fast wheels' that go onto my 531 framed Raleigh 'Road Ace' they run at 160psi rear and 140 front.

Not sure, I'll have a look tomorrow, they came from Bob Warners when John used to get them for Cliff Smith who used them as training tyres but after Cliff died he'd a couple left and let me have one when I asked about 'lighter tyres' for mine. Cliff had 2 bikes almost identical but one had tubs and the other clinchers (both with 'ultraclose' SA hubs)

EDIT - he talks about it from 2 minutes on.
