>>1007003I dont think it matters really. There's a lot more to a bike than specs.
I mean you can put 105 on a pile of garbage, and you still have garbage
People just overlook frame quality because there's nothing quantifiable about it. You can say sure tiagra is better than sora, or that one bike has 8 speeds vs 11, but really frame quality doesnt have that. Sure there's weight but you can have a shitty light bike still.
And ultimately the frame is the most important part of the bike. you can upgrade components all you want, but you can never upgrade a frame. that's just called getting a new bike
