I finally got this after the shipping company lost it twice and then delivered to the wrong address in the middle of a lockdown. It turned up the day before we entered another lockdown, so provided some good workshop time building.
Short version, I'm blown away. It's more comfortable than my Moots was, it's a fair bit lighter, and with the massive tyre clearance and very slight geo tweaks it's super capable, even with pretty challenging singletrack. There are a couple of minor tweaks still to make, mostly cosmetic. Steel frame, carbon seat tube.
The Ultradynamico tyres in the first picture ride amazingly, but holy jeebus are they soft - really noticeable tread wear after two rides. I've swapped a pair of Rene Herse tyres on and they've definitely been more capable. Cushcore is a huge benefit.
