The Genesis Zero 1 is reviewed here. Sums up well what I think. Frames available in store and stock builds too.

Genesis Equilibrium disc 20 reviewed here. The weight of the bike is not a problem I climb quite quickly on bikes of a similar weight. It not a racing bike after all. Otherwise the review seem fair. Frames available in store for custom builds that can be lighter if you want!
