thanks! yours is awesome too. It weights 13kg without the bottle. I can remove ~300-500g of the weight by changing saddle, chain, stem and by removing some other utility stuff but it does not worth it.
It's covered with 3m paint protector (sprayed rubber film). It's glossy) I did not like matte finish and was too lazy to put helitape on. It's pretty durable, and can easily be removed.
