Radar: 70g, advantage Canyon (based on Varia 515 weight)
Headlight: 150g, advantage Canyon (based on typical headlight with battery)
Seatpost: negligible (220g for Canyon not that light, C’Dale specs 350mm post - fairly long)
Tires: 40g (Conti GP5k likely weigh just a bit lighter than Rubinos in the same size)

= ~610g

This leaves 500g unexplained, though I think the two likeliest are:
- C’Dale measures a 56cm, no idea what size Canyon measures
