I remember biketech bottom of Park st, Bristol (rip

) selling black folding porcs for £5 each.
Porcs were terrible tyres and possibly also the quickest to deteriorate from not great to semi-slick.
I was astonished at how little grip they offered on almost surface.
I took them off pronto and sold them on.
We know now a crisp, sharp, straight edge gives grip.
Not a smooth round dimple
Light, good looking, a lovely sound on tarmac and a pretty print on the ground, but otherwise useless. No wonder they got sold off for a fiver - but they would've made a sound investment because at current prices they have outperformed the housing market.
Although you can't live in a boxed onza, unless you're a spider or a ladybird.
