WORLD'S LIGHTEST DISC BRAKE ROADBIKE? 4.64kg S-WORKS AETHOS

Is this the lightest fully hydraulic disc brake 2x road bike in the world? InCycle down in the south of China built this very impressive 4.64kg S-WORKS Aethos. They were curious as to if this was the lightest disc brake road bike in the world, so figured the easiest way was to show this to the world. With no real presence on western social media, they asked me to help out and upload it here. I re-edited their build video and put it up for ya'll to see.

//Notes// 📝
This bike was original built up by InCycle and a video shot by them. They gave me written permission to re-edit and re-upload their content here. I'm also curious why the latest Specialized frames say "Handmade in Taiwan" - It's fairly well-known that the frames are made here in Xiamen. (I won't mention the factory name out of respect for both parties) I'm fairly sure Spesh assemble their full bikes in Taiwan, but... Xiamen is definitely not in Taiwan. 😂
