Yes, it seems taobao is the only place you can buy them, but that's alright since you can use visa card and deliver it with forwarder. Regarding frame geometry and look, it doesn't look like SL7, the closes I found is Canyon Aeroad, look at the thick fork and curves.
I think this bike is just top notch by looking to the price, I bought every component by myself and it was around 1800$ with 105 11 speed mechanical and aluminum Dtswiss e1800 used wheels, so it's a steal if you ask me.
