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.

Unfortunately I'm not a Chinese speaker and I can't even register with taobao without going through an untranslatable registration process so it doesn't look good for me being able to access this build lol

I know I'm not technically capable of building an entire bike from the frame up, so I've been looking for the cheapest complete di2/etap bike that has the geometry for crit racing.  Does this Cycletrack Sky model fit my criteria? To my uneducated eye it looks like an SL7 replica? I've visit3d Cycletracks website but everything seems to be sold out so I'm wondering if Taobao is the only place that is selling them?
