Back of bike looks like this: https://images2.giant-bicycles.com/b_white%2Cc_pad%2Ch_2000%2Cq_80/echrgwx2h6rhmtslciqh/MY21FastRoadAdvanced1_ColorACarbon-9.jpg
Are there any light back racks that are compatible with this bike? I can see a screw hole just above the wheel, in the middle of the back fork, but it doesn't have the standard two screw holes on the sides of the back fork.
Edit: This one and this one from Giant appears to work (they look nearly identical). Any lighter aftermarket ones?
In general, while I imagine back racks on carbon bikes isn't a thing, for those who have done it or have some experience, how much weight would be safe to put on a back rack on a carbon bike before one starts worrying about torsion/flex of the frame?
