Maybe you already read it in the forum - York Uno is currently testing a new very light and short Ares frame calledAY Spear. The production model will have a top tube length of 470mm, RC 315mm, HA 75 degree and the weight is 1.5kg / 3.3lbs. That means it´s even a little bit lighter than the Paris III and 150g lighter than previous Ares AY model.
York has a personal prototype with slightly different specs: RC 280mm and weight 1.46kg / 3.2lbs. But it looks like this version is not going to be produced.
On the left side you can see York´s built up AY Spear.
