I don't build frames like this much these days. It has a traditional level top tube and will only take a single chainring. This is what you might call an old-school 'cross frame except that it will have a carbon fork.
This frame was exactly 4 lbs. in it's finished state-not bad for steel in a non-compact format.
I could only do gradual bends in the Reynolds 725 seatstays......they are mega-stiff. I was surprised at how stiff they were given that they are very thin wall , about as thin as I dare on a bike with cantilever mounts.
