This is for 2021 or 2022 bikes (and maybe 2020). Trek claims the XTR bike is 350g lighter than the X01 bike. I did some rough math on the components that are different and see the XTR bike at around 50g lighter at best. Anyone compare these two in a bike shop or otherwise hands on in regards to weight? The 350g claim seems to be a lie which I guess is the point of my post. Lying is bad.
