Giant vs Bianchi....
I've had 6 Giant bikes. Road and MTB at the upper end of their catalogue. All great bikes at a fair price point. Only one carbon framed road bike suffered at the hands of Parisian baggage handlers......
Bianchi; a much older and storied company. I've only had 2, both made in Italy and CrMo. Delightful bikes, full Campagnolo - you get the idea.... $$$$$$$!
For years, Bianchi have been threatening to move their full production to Italy. So far, the bulk of frames are still manufactured in China, or Taiwan, and assembled back 'home'.
At similar pricepoints, I'd argue that Giant is the superior product with better components. Of course, it doesn't have the iconic head badge, nor celeste paint option. These things may matter at the coffee stop or sharing on Insta. After all, Bianchi have won 64 Grand Tour stages!
But so have Giant....... so better get a Pinarello.
