Hi, Iv been on the hunt for a new road bike build for a while now. What I want is an aero shape with disk brakes. I am a fairly big rider so superlight frames don't really work for me. What I have my eye on it this frame https://www.aliexpress.com/item/4000672137626.html?spm=a2g0s.8937460.0.0.4b202e0e0K6WCC which can't be beaten on price. Anyone got any experience on this? also, they have this note which I don't understand: "ATT: The headset of the frame does not need the bottom bearing" anyone shed some light on this would be helpful.
