If it is, it will probably be the lightest steel frame and forks in the world. I'm fairly certain 2350g will be the frame only and the forks will be another 800g to 1200g.
It can't be a ritchey
First the weight of the frame (really too heavy), and there's not the specific design of a ritchey frame for the seatpost collar area : On all the ritchey, the seatpost are not weld directly on the seat tube, but on the "seatpost clamp hole"
I don't have a picture of one similar, nor have I ever seen one in real life or on the net, but why would they write 'Ritchey' on it if it wasn't a Ritchey? Irrefutable I'm sure you will agree.
like a Scott I had, was built on columbus MAX tubing and had Ritchey dropouts... it was not a Ritchey frame... and the old Pinarello I have has Campagnolo dropouts - its not a campagnolo frame...
At 2350g, about 5.2lb, it's a bit heavier than the very lightest steel MTB frames, which can be as low as ~2000g/~4lb, but once built up I think you'd be hard pressed to notice that extra 500g/1lb. It's quite possible you might actually prefer the ride quality of a slightly heavier/stiffer frame if you were able to try them back to back.
The fact that it uses Ritchey dropouts and not plain, unbranded ones means it's probably a fairly decent frame and Like I said, well worth building up and trying out. The nickel/chrome finish, not sure what it is, is rather nice too.
