Yes, let's not forget that the OStro I weighed was only HALF white, which suggest fully painted would be more in the 950g range.
As far as I know there was NEVER a 780g Ostro V1. My Flickr was one of the lightest at 826g, a friend's also bought early 21 was 824g. Later, the weight went up, even for Flickrs.
If I buy a Porsche with stated 400hp but it only has 350, I would complain.
If I bought a dishwasher rated at 42dB, but it was 55, I would complain.
How come the bike companies can get away with it? By sowing confusion with paint colours, sizes, etc.
Anyway, my mind is made up; having scoured the Internet I've found and ordered an SL8 frame in Ready to Paint in 52. Hoping this will be around 675g and the fork less than 350. This would be almost 400g lighter than an Ostro V2. As for durability, it's an American company so I would hope they have confidence in their product. I know we have seen recalls from Speech in the past, but they seem to be have been handled well.
