Nice one Mr K., I was about to post that interview with Dave Wrath-Sharman from 63XC.COM.
He certainly has some very interesting views on putting together a bomb-proof off-road bike. Looking at the http://www.highpath.co.uk/
site, they do a couple of very well made products (like the Egg Rings that Chris Boardman used to break the hour record).
But, in typical British fashion, their market presence is almost zero. And some of the products they can (allegedly) make like fixie cogs for 6-bolt ISO disc hubs are not even mentioned on their site.
It's hardly surprising that nobody knows of their contribution to early UK MTB development.
Contrast the way that innovations within CK's peer group spawned a global industry...
[EDIT] ** I think I was a bit unfair in my criticism of them not having any interest in re-introducing the hub brake.
Reading the article again: What D W-S actually said was that, "off-the-shelf" hub brakes could not be adapted satisfactorily for MTB use. So specific parts needed to be manufactured by Highpath. And these might result in a non-standard hub spacing. So both the tooling costs and implications for framebuilding presented barriers.
I guess the difference is that the Marin County pioneers found customers prepared to support their ideas and buy into the new type of bikes. Innovation, risk and marketing - Areas where we Brits don't always get the combination right, sadly **[/EDIT]
