6.6kg Bianchi Oltre XR4 Disc

Swapped out my wheelset and tyres and the weight went from 7.4kg to 6.6kg!
Was previously using a custom 60mm wheelset with Chris King R45D hubs.
Current pair of wheels is the 990g 45mm Avian CR5 DB, paired with Maxxis High Road SL (tubed) and Maxxis Ultralight inner tubes.

Possibly the lightest Oltre XR4 Disc out there? Been scouring through forums but it seems most Oltres are paired with deeper wheels and weigh in at low 7s. I would love to be proven wrong if anyone has an even lighter Oltre build!
