You mean a Wishbone seatstay. Not sure the benefits, but figured I’ll give you the right term

Do you mean a wishbone seat stay? it looks cool might be lighter, not sure other than that.

Its called a wishbone. There are a few reasons but i think in modern frames its mostly an aesthetic choice. It can offer wider tire clearance, better aerodynamics, more compliance in those stays to make a more comfortable ride, and in some/most instances a lighter frame.

I’m sure there is some theoretical diffence it makes w.r.t. to stiffness, but I would dare say that it’s mostly a design decision. Giant used to do this on all their bikes up until maybe 2000 (!?) and I would assume the idea was to simply add a unique and recognizable element, similar to the GT triangle.

Supposedly making the rear triangle smaller transfers power to the rear wheel efficiently( smaller triangle=stiffer).The single tube is supposed to flex a bit and be a more comfortable ride as well. But I’ve never ridden one.

I believe wishbone seatstays were significantly cheaper for some companies operating in the 90s so became popular on some models. I don’t know that they actually have any advantages over traditional seatstays.
