Fashion, the conical hub was used on the Manx Norton and was racy, that also make them expensive hubs as the Cafe racers use them as even at these prices they are cheaper than the genuine Manx hubs.

Style, lightness and cost of manufacture, but not necessarily in that order.

Why do you ask?

I'm sure someone on here compared weights with the QD hubs and found the QD hubs to be lighter.

That is what happens when you employ external stylist to design a bike.

Jist curious. Was wondering if there were real benefits to the design or just an ugly attempt by bsa/triumph to stay relative in the market at the time..

When the previous 2 designs (other being full width cast hubs) meant you could remove the back wheel with out touching the chain, then with the conical hub you had to remove it, pretty much a backwards step. They didn’t even open up the slot on back of the swing arm to aid removal like the B44’s and later on jap bikes had.

I may be wrong but there are 2 OIF bikes here and looking at the conical brake I see hints of Formula 1 early late 60s early70s era brake scoops and racebike scoops from same time period that and the 'ceriani' type forks and skinny fenders with wire 'stays' all scream 'make it look mod' PS I love the quick detach feature on the rear wheel of my 68 A65
