1160g for a 52 is much more than advertised. What's included? i see you weight the fork with the thru axle, for example, you should substract it. Ditto for the frame if you included it?
The plastic cable guides should weigh almost nothing, but maybe 15g? The derailleur hangers, front and back, are probably one? And the bottle cages bolts? Is the down tube sock included?
My 268 was 1160g in matt black, 1190g in gloss black, with cable guides, with both derailleur hangers, and bottle cages bolts. Medium.
According to LT, there should be a several hundred gram difference between the 268 and the 301.
Yes, white paint weighs more, but still...
