I built one up recently and had my first proper ride on it today and was very impressed.
My first entry into Carbon and i went for the Dirty Harry instead of a Lurcher as i liked the normal Bottom bracket rather than pressfit.
My XL frame weighs 2.75lbs (4.25lbs lighter than my Honzo!) and has built up into a 25lb (including pedals) bike without any weight weenie additions. Reba Maxle forks, Hope Pro2 on Arch Ex, XT 2×10 with a SLX Clutch mech. Climbed really well today in the Wyre forest and didn’t feel at all fragile with my 15/16st on it.
Bought mine the day before they put them up £50 to £450 which was nice too. I’d definitely recommend one after my experience today but obviously i have no long term test of it yet so time will tell how it bears up to regular use.
