Hello from here!
I don't know,but somehow this is my favourite tyre brand. Every year I get a copy of their current product-catalogue: a kind of faculty book on contemporary bicycle tyres. K-Nobs are from the beginning of the last decade(luckily enough these were stored properly:no signs of aging),
as far as I know nowadays Vredestein does not make manufactured tyres.
The bike itself is a Velo Schauff (check out here: http://www.schauff.de/schauff/index.php ... language=e) Highvoltage from '97. I purchased it 2 months ago:this is my current winter-workbike http://www.retrobike.co.uk/forum/viewto ... &start=405
Non-marked cro-moly steel lugged frame,Shimano 100GS groupset(pedals NOS Shimano Exage Trail). A very solid bike,rides smooth,all parts work fine -as it is a brand new one. I've changed the originally fitted ugly steel mudguards to light plastic pieces an fitted the rubber flaps. http://www.retrobike.co.uk/forum/viewto ... &start=420
Still not a beauty,but absolutely functional.
